|
||||
============
|
||||
|
||||
Want to contribute? Great! First, read this page (including the small print at
|
||||
the end).
|
||||
|
||||
# Before you contribute
|
||||
Before we can use your code, you must sign the
|
||||
[Google Individual Contributor License Agreement](https://developers.google.com/open-source/cla/individual?csw=1)
|
||||
(CLA), which you can do online. The CLA is necessary mainly because you own the
|
||||
copyright to your changes, even after your contribution becomes part of our
|
||||
codebase, so we need your permission to use and distribute your code. We also
|
||||
need to be sure of various other things—for instance that you'll tell us if you
|
||||
know that your code infringes on other people's patents. You don't have to sign
|
||||
the CLA until after you've submitted your code for review and a member has
|
||||
approved it, but you must do it before we can put your code into our codebase.
|
||||
Before you start working on a larger contribution, you should get in touch with
|
||||
us first through the issue tracker with your idea so that we can help out and
|
||||
possibly guide you. Coordinating up front makes it much easier to avoid
|
||||
frustration later on.
|
||||
|
||||
# Code reviews
|
||||
All submissions, including submissions by project members, require review. We
|
||||
use Github pull requests for this purpose.
|
||||
|
||||
# The small print
|
||||
Contributions made by corporations are covered by a different agreement than
|
||||
the one above, the Software Grant and Corporate Contributor License Agreement.

TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION
|
||||
|
||||
1. Definitions.
|
||||
|
||||
"License" shall mean the terms and conditions for use, reproduction,
|
||||
and distribution as defined by Sections 1 through 9 of this document.
|
||||
|
||||
"Licensor" shall mean the copyright owner or entity authorized by
|
||||
the copyright owner that is granting the License.
|
||||
|
||||
"Legal Entity" shall mean the union of the acting entity and all
|
||||
other entities that control, are controlled by, or are under common
|
||||
control with that entity. For the purposes of this definition,
|
||||
"control" means (i) the power, direct or indirect, to cause the
|
||||
direction or management of such entity, whether by contract or
|
||||
otherwise, or (ii) ownership of fifty percent (50%) or more of the
|
||||
outstanding shares, or (iii) beneficial ownership of such entity.
|
||||
|
||||
"You" (or "Your") shall mean an individual or Legal Entity
|
||||
exercising permissions granted by this License.
|
||||
|
||||
"Source" form shall mean the preferred form for making modifications,
|
||||
including but not limited to software source code, documentation
|
||||
source, and configuration files.
|
||||
|
||||
"Object" form shall mean any form resulting from mechanical
|
||||
transformation or translation of a Source form, including but
|
||||
not limited to compiled object code, generated documentation,
|
||||
and conversions to other media types.
|
||||
|
||||
"Work" shall mean the work of authorship, whether in Source or
|
||||
Object form, made available under the License, as indicated by a
|
||||
copyright notice that is included in or attached to the work
|
||||
(an example is provided in the Appendix below).
|
||||
|
||||
"Derivative Works" shall mean any work, whether in Source or Object
|
||||
form, that is based on (or derived from) the Work and for which the
|
||||
editorial revisions, annotations, elaborations, or other modifications
|
||||
represent, as a whole, an original work of authorship. For the purposes
|
||||
of this License, Derivative Works shall not include works that remain
|
||||
separable from, or merely link (or bind by name) to the interfaces of,
|
||||
the Work and Derivative Works thereof.
|
||||
|
||||
"Contribution" shall mean any work of authorship, including
|
||||
the original version of the Work and any modifications or additions
|
||||
to that Work or Derivative Works thereof, that is intentionally
|
||||
submitted to Licensor for inclusion in the Work by the copyright owner
|
||||
or by an individual or Legal Entity authorized to submit on behalf of
|
||||
the copyright owner. For the purposes of this definition, "submitted"
|
||||
means any form of electronic, verbal, or written communication sent
|
||||
to the Licensor or its representatives, including but not limited to
|
||||
communication on electronic mailing lists, source code control systems,
|
||||
and issue tracking systems that are managed by, or on behalf of, the
|
||||
Licensor for the purpose of discussing and improving the Work, but
|
||||
excluding communication that is conspicuously marked or otherwise
|
||||
designated in writing by the copyright owner as "Not a Contribution."
|
||||
|
||||
"Contributor" shall mean Licensor and any individual or Legal Entity
|
||||
on behalf of whom a Contribution has been received by Licensor and
|
||||
subsequently incorporated within the Work.
|
||||
|
||||
2. Grant of Copyright License. Subject to the terms and conditions of
|
||||
this License, each Contributor hereby grants to You a perpetual,
|
||||
worldwide, non-exclusive, no-charge, royalty-free, irrevocable
|
||||
copyright license to reproduce, prepare Derivative Works of,
|
||||
publicly display, publicly perform, sublicense, and distribute the
|
||||
Work and such Derivative Works in Source or Object form.
|
||||
|
||||
3. Grant of Patent License. Subject to the terms and conditions of
|
||||
this License, each Contributor hereby grants to You a perpetual,
|
||||
worldwide, non-exclusive, no-charge, royalty-free, irrevocable
|
||||
(except as stated in this section) patent license to make, have made,
|
||||
use, offer to sell, sell, import, and otherwise transfer the Work,
|
||||
where such license applies only to those patent claims licensable
|
||||
by such Contributor that are necessarily infringed by their
|
||||
Contribution(s) alone or by combination of their Contribution(s)
|
||||
with the Work to which such Contribution(s) was submitted. If You
|
||||
institute patent litigation against any entity (including a
|
||||
cross-claim or counterclaim in a lawsuit) alleging that the Work
|
||||
or a Contribution incorporated within the Work constitutes direct
|
||||
or contributory patent infringement, then any patent licenses
|
||||
granted to You under this License for that Work shall terminate
|
||||
as of the date such litigation is filed.
|
||||
|
||||
4. Redistribution. You may reproduce and distribute copies of the
|
||||
Work or Derivative Works thereof in any medium, with or without
|
||||
modifications, and in Source or Object form, provided that You
|
||||
meet the following conditions:
|
||||
|
||||
(a) You must give any other recipients of the Work or
|
||||
Derivative Works a copy of this License; and
|
||||
|
||||
(b) You must cause any modified files to carry prominent notices
|
||||
stating that You changed the files; and
|
||||
|
||||
(c) You must retain, in the Source form of any Derivative Works
|
||||
that You distribute, all copyright, patent, trademark, and
|
||||
attribution notices from the Source form of the Work,
|
||||
excluding those notices that do not pertain to any part of
|
||||
the Derivative Works; and
|
||||
|
||||
(d) If the Work includes a "NOTICE" text file as part of its
|
||||
distribution, then any Derivative Works that You distribute must
|
||||
include a readable copy of the attribution notices contained
|
||||
within such NOTICE file, excluding those notices that do not
|
||||
pertain to any part of the Derivative Works, in at least one
|
||||
of the following places: within a NOTICE text file distributed
|
||||
as part of the Derivative Works; within the Source form or
|
||||
documentation, if provided along with the Derivative Works; or,
|
||||
within a display generated by the Derivative Works, if and
|
||||
wherever such third-party notices normally appear. The contents
|
||||
of the NOTICE file are for informational purposes only and
|
||||
do not modify the License. You may add Your own attribution
|
||||
notices within Derivative Works that You distribute, alongside
|
||||
or as an addendum to the NOTICE text from the Work, provided
|
||||
that such additional attribution notices cannot be construed
|
||||
as modifying the License.
|
||||
|
||||
You may add Your own copyright statement to Your modifications and
|
||||
may provide additional or different license terms and conditions
|
||||
for use, reproduction, or distribution of Your modifications, or
|
||||
for any such Derivative Works as a whole, provided Your use,
|
||||
reproduction, and distribution of the Work otherwise complies with
|
||||
the conditions stated in this License.
|
||||
|
||||
5. Submission of Contributions. Unless You explicitly state otherwise,
|
||||
any Contribution intentionally submitted for inclusion in the Work
|
||||
by You to the Licensor shall be under the terms and conditions of
|
||||
this License, without any additional terms or conditions.
|
||||
Notwithstanding the above, nothing herein shall supersede or modify
|
||||
the terms of any separate license agreement you may have executed
|
||||
with Licensor regarding such Contributions.
|
||||
|
||||
6. Trademarks. This License does not grant permission to use the trade
|
||||
names, trademarks, service marks, or product names of the Licensor,
|
||||
except as required for reasonable and customary use in describing the
|
||||
origin of the Work and reproducing the content of the NOTICE file.
|
||||
|
||||
7. Disclaimer of Warranty. Unless required by applicable law or
|
||||
agreed to in writing, Licensor provides the Work (and each
|
||||
Contributor provides its Contributions) on an "AS IS" BASIS,
|
||||
WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
|
||||
implied, including, without limitation, any warranties or conditions
|
||||
of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
|
||||
PARTICULAR PURPOSE. You are solely responsible for determining the
|
||||
appropriateness of using or redistributing the Work and assume any
|
||||
risks associated with Your exercise of permissions under this License.
|
||||
|
||||
8. Limitation of Liability. In no event and under no legal theory,
|
||||
whether in tort (including negligence), contract, or otherwise,
|
||||
unless required by applicable law (such as deliberate and grossly
|
||||
negligent acts) or agreed to in writing, shall any Contributor be
|
||||
liable to You for damages, including any direct, indirect, special,
|
||||
incidental, or consequential damages of any character arising as a
|
||||
result of this License or out of the use or inability to use the
|
||||
Work (including but not limited to damages for loss of goodwill,
|
||||
work stoppage, computer failure or malfunction, or any and all
|
||||
other commercial damages or losses), even if such Contributor
|
||||
has been advised of the possibility of such damages.
|
||||
|
||||
9. Accepting Warranty or Additional Liability. While redistributing
|
||||
the Work or Derivative Works thereof, You may choose to offer,
|
||||
and charge a fee for, acceptance of support, warranty, indemnity,
|
||||
or other liability obligations and/or rights consistent with this
|
||||
License. However, in accepting such obligations, You may act only
|
||||
on Your own behalf and on Your sole responsibility, not on behalf
|
||||
of any other Contributor, and only if You agree to indemnify,
|
||||
defend, and hold each Contributor harmless for any liability
|
||||
incurred by, or claims asserted against, such Contributor by reason
|
||||
of your accepting any such warranty or additional liability.
|
||||
|
||||
END OF TERMS AND CONDITIONS
|
||||
|
||||
APPENDIX: How to apply the Apache License to your work.
|
||||
|
||||
To apply the Apache License to your work, attach the following
|
||||
boilerplate notice, with the fields enclosed by brackets "[]"
|

|
||||
comment syntax for the file format. We also recommend that a
|
||||
file or class name and description of purpose be included on the
|
||||

API Reference {#mathfu_api_reference}
|
||||
=============
|
||||
|
||||
This document describes all classes, functions, macros and files that make
|
||||
up the [MathFu][] library. This is intended to be used as a reference for
|
||||
C++ programmers who are familiar with [geometry][], [vectors][], [matrices][],
|
||||
[quaternions][] and [linear algebra][].
|
||||
|
||||
The API reference is broken into the following sections:
|
||||
* [Build Configuration](@ref mathfu_build_config)
|
||||
- Describes configuration options for [MathFu][] code generation.
|
||||
* [Allocators](@ref mathfu_allocator)
|
||||
- Allocators to simplify the process of memory allocation for [MathFu][]
|
||||
data structures.
|
||||
* [Constants](@ref mathfu_constants)
|
||||
- Constants to use in conjunction with [MathFu][] classes.
|
||||
* [Vectors](@ref mathfu_vector)
|
||||
- Class and functions to manipulate [vectors][].
|
||||
* [Matrices](@ref mathfu_matrix)
|
||||
- Class and functions to manipulate [matrices][].
|
||||
* [Quaternions](@ref mathfu_quaternion)
|
||||
- Class and functions to manipulate [quaternions][].
|
||||
* [GLSL Mappings](@ref mathfu_glsl)
|
||||
- Mappings to GLSL data types and functions.
|
||||
* [Utility Functions](@ref mathfu_utilities)
|
||||
- Variety of useful functions that can be used with
|
||||
[Vector](@ref mathfu::Vector) and [Matrix](@ref mathfu::Matrix)
|
||||
classes.
|
||||
* [Version Constants](@ref mathfu_version)
|
||||
- Constants which identify the library version.

MathFu {#mathfu_index}
|
||||
======
|
||||
|
||||
# Overview {#mathfu_overview}
|
||||
|
||||
[MathFu][] is a C++ math library developed primarily for games focused on
|
||||
simplicity and efficiency.
|
||||
|
||||
It provides a suite of [vector][], [matrix][] and [quaternion][] classes
|
||||
to perform basic [geometry][] suitable for game developers. This functionality
|
||||
can be used to construct geometry for graphics libraries like [OpenGL][] or
|
||||
perform calculations for animation or physics systems.
|
||||
|
||||
[MathFu] can be downloaded from [GitHub](http://github.com/google/mathfu) or
|
||||
the [releases page](http://github.com/google/mathfu/releases).
|
||||
|
||||
**Important**: MathFu uses submodules to reference other components it depends
|
||||
upon so download the source using:
|
||||
|
||||
~~~{.sh}
|
||||
git clone --recursive https://github.com/google/mathfu.git
|
||||
~~~
|
||||
|
||||
# Functionality
|
||||
|
||||
Each [vector][], [matrix][] and [quaternion][] class implements basic
|
||||
arithmetic operators (addition, subtraction, multiplication, division) in
|
||||
addition to simple [linear algebra][] operators (e.g dot product,
|
||||
cross product, inverse, slerp).
|
||||
|
||||
# Optimization
|
||||
|
||||
[MathFu][] is optimized using [SIMD][] instructions (including [NEON][] for
|
||||
[ARM][] and [SSE][] for [x86][] architectures). [SIMD][] optimization is
|
||||
enabled by default based upon the target platform and compiler options used
|
||||
to build a project. In addition, [MathFu][] provides compile time options to
|
||||
modify code generation, see [Build Configurations][] for more details.
|
||||
|
||||
# Supported Platforms
|
||||
|
||||
[MathFu][] has been tested on the following platforms:
|
||||
|
||||
* [Android][]
|
||||
* [Linux][] (x86_64)
|
||||
* [OS X][]
|
||||
* [Windows][]
|
||||
|
||||
This library is entirely written in C++ with the exception of some
|
||||
conditionally enabled compiler intrinsics and some workarounds for different
|
||||
compiler quirks, which means that it *should* work with either no or little
|
||||
modification on any platform that has a C++ compiler.
|
||||
|
||||
# Feedback and Reporting Bugs
|
||||
|
||||
* Discuss MathFu with other developers and users on the
|
||||
[MathFu Google Group][].
|
||||
* File issues on the [MathFu Issues Tracker][].
|
||||

Building {#mathfu_guide_building}
|
||||
========
|
||||
|
||||
# Integration Options {#mathfu_guide_building_options}
|
||||
|
||||
[MathFu][] is designed as a C++ header only library to simplify the process
|
||||
of including the library in projects. [MathFu] provides the following options
|
||||
for using it in a project:
|
||||
|
||||
* [Manually configure the compiler][] by simply include the appropriate
|
||||
headers into a project's source code.
|
||||
* Use the [CMake project][].
|
||||
* Include the [Android NDK project][] when developing for [Android][]
|
||||
|
||||
Before diving into using [MathFu][] in your project, we recommend you spend
|
||||
some time building and running the unit tests for each platform you wish to
|
||||
target by working through the following sections:
|
||||
|
||||
* [Building for Android][]
|
||||
* [Building for Linux][]
|
||||
* [Building for OS X][]
|
||||
* [Building for Windows][]
|
||||
|
||||
# Manual Compiler Configuration {#mathfu_guide_building_compiler_config}
|
||||
|
||||
The following directories need to be added to the include paths of a project
|
||||
to build the default configuration:
|
||||
* `mathfu/include`
|
||||
* `vectorial/include`
|
||||
- If [vectorial][] was downloaded with the [MathFu][] project, this
|
||||
will be located under the `dependencies/` directory.
|
||||
|
||||
In addition, to compile with [SIMD][] enabled an architecture specific flag
|
||||
must be specified:
|
||||
|
||||
Architecture | Compiler | Flag
|
||||
----------------|---------------------|------------
|
||||
[x86][] | Android GCC / Clang | -msse
|
||||
[x86_64][] | Android GCC / Clang | -msse4.1
|
||||
[x86][] | GCC / Clang | -msse4.1
|
||||
[ARM][] | GCC / Clang | -mfpu=neon
|
||||
[x86][] | Visual Studio | /arch:SSE2
|
||||
|
||||
For example, to compile the following file `test.cpp` against [MathFu][] with
|
||||
gcc for x86:
|
||||
|
||||
~~~{.cpp}
|
||||
#include <stdio.h>
|
||||
#include "mathfu/vector.h"
|
||||
|
||||
int main(int argc, char *argv[]) {
|
||||
mathfu::Vector<float, 3> v1(1.0f, 2.0f, 3.0f), v2(3.0f, 2.5f, 0.5f), v3;
|
||||
v3 = v1 + v2;
|
||||
printf("%.1f %.1f %.1f\n", v3.x(), v3.y(), v3.z());
|
||||
return 0;
|
||||
}
|
||||
~~~
|
||||
|
||||
requires the following command line (assuming vectorial is in the
|
||||
`mathfu/dependencies` directory):
|
||||
|
||||
~~~{.sh}
|
||||
g++ -Imathfu/include -Imathfu/dependencies/vectorial/include test.cpp -msse4.1
|
||||
~~~
|
||||
|
||||
In addition, [MathFu][] provides a set of build configuration options that
|
||||
are controlled using preprocessor symbols described by [Build Configuration][].
|
||||
|
||||
# CMake {#mathfu_guide_building_cmake}
|
||||
|
||||
[MathFu][] uses a [CMake][] project to build unit tests and benchmarks
|
||||
for [Linux][], [OS X][] and [Windows][].
|
||||
|
||||
[CMake][] is used to generate a platform projects for each target platform:
|
||||
* [Makefiles][] ([Linux][] / [OS X][])
|
||||
* [Xcode][] projects ([OS X][])
|
||||
* [Visual Studio][] projects ([Windows][])
|
||||
|
||||
If you're not familiar with [CMake][], see the following sections to learn how
|
||||
to build on each platform:
|
||||
|
||||
* [Building for Linux][]
|
||||
* [Building for OS X][]
|
||||
* [Building for Windows][]
|
||||
|
||||
In addition to building the [MathFu][] unit tests and benchmarks,
|
||||
the [MathFu][] [CMake][] project can be used in developers own projects by:
|
||||
|
||||
* Disabling the build of unit tests and benchmarks using the options:
|
||||
- `mathfu_build_benchmarks`
|
||||
- `mathfu_build_tests`
|
||||
* Including the [CMake][] project.
|
||||
* Using the `mathfu_configure_flags` function to add the appropriate
|
||||
include directories and compiler flags for the project.
|
||||
|
||||
For example, in a CMakeLists.txt project file which contains the executable
|
||||
`mygame`:
|
||||
|
||||
~~~
|
||||
# Include MathFu in this project with test and benchmark builds disabled
|
||||
# then add MathFu compiler flags to the mygame build target.
|
||||
set(mathfu_build_benchmarks OFF CACHE BOOL "")
|
||||
set(mathfu_build_tests OFF CACHE BOOL "")
|
||||
add_subdirectory(path/to/mathfu mathfu)
|
||||
|
||||
mathfu_configure_flags(mygame)
|
||||
~~~
|
||||
|
||||
[MathFu][] build options (see [Build Configuration][]) can be configured
|
||||
with the `mathfu_configure_flags` function using the optional arguments
|
||||
`enable_simd` and `force_padding`. For example:
|
||||
|
||||
Function Call | Build Configuration
|
||||
--------------------------------------------|----------------------------------
|
||||
`mathfu_configure_flags(mygame)` | Default, SIMD & padding enabled.
|
||||
`mathfu_configure_flags(mygame TRUE FALSE)` | SIMD enabled & padding disabled.
|
||||
`mathfu_configure_flags(mygame FALSE)` | SIMD disabled.
|
||||
|
||||
See the function comment in the CMakeLists.txt file for more information.
|
||||
|
||||
# Android NDK Makefiles {#mathfu_guide_building_android_makefiles}
|
||||
|
||||
If you're not familiar developing applications with the [Android NDK][],
|
||||
see [Building for Android][] first.
|
||||
|
||||
To use [MathFu][] with an [Android NDK][] makefile project, add the following
|
||||
lines to your project's `Android.mk` file.
|
||||
|
||||
~~~{.mk}
|
||||
# Add the empty MathFu static library target to configure the project.
|
||||
LOCAL_STATIC_LIBRARIES += libmathfu
|
||||
|
||||
# This is used to build your project's shared library, this should already
|
||||
# be in your Android.mk makefile.
|
||||
include $(BUILD_SHARED_LIBRARY)
|
||||
|
||||
# Add the directory containing MathFu to the module search path.
|
||||
$(call import-add-path,$(abspath path/to/mathfu/..))
|
||||
# Import the MathFu project.
|
||||
$(call import-module,mathfu/jni)
|
||||
~~~
|
||||
|
||||
[MathFu][] build options (see [Build Configuration][]) can be configured
|
||||
by linking against the different static libraries the [MathFu][] project
|
||||
builds:
|
||||
|
||||
Library | Build Configuration
|
||||
-----------------------|--------------------------------------------------
|
||||
`libmathfu` | Default configuration, SIMD and padding enabled.
|
||||
`libmathfu_no_padding` | SIMD enabled (if supported), padding disabled.
|
||||
`libmathfu_no_simd` | SIMD disabled, padding disabled.

Building for Android {#mathfu_guide_building_android}
|
||||
====================
|
||||
|
||||
# Version Requirements {#mathfu_guide_building_android_version}
|
||||
|
||||
Following are the minimum tested versions of the tools and libraries you
|
||||
need to build [MathFu][] for Android:
|
||||
|
||||
* [Android SDK][]: Android 2.3.3 (API Level 10) or above.
|
||||
* [Android Developer Tools][] ([ADT][]): 20140702
|
||||
- NDK plugn for Eclipse (bundled with [ADT][]) if using Eclipse to build.
|
||||
* [Android NDK][]: android-ndk-r10e
|
||||
* [fplutil][]: 1.0 or above, if using [fplutil][] to build, install and run.
|
||||
|
||||
# Prerequisites {#mathfu_guide_building_android_prerequisites}
|
||||
|
||||
Prior to building:
|
||||
|
||||
* Install the [Android SDK][].
|
||||
* Install the [Android NDK][].
|
||||
* Install [fplutil prerequisites][] if using [fplutil][] to build, install
|
||||
and run.
|
||||
|
||||
# Building {#mathfu_guide_building_android_building}
|
||||
|
||||
Each [MathFu][] project for Android has an associated `AndroidManifest.xml`
|
||||
file and `jni` subdirectory. Unit tests and benchmarks directories contain
|
||||
projects that each build an Android package ([apk][]) which can be installed
|
||||
and executed on Android devices.
|
||||
|
||||
The following directories in the [MathFu] project contain [Android NDK][]
|
||||
projects:
|
||||
|
||||
* `mathfu/`
|
||||
- Rules used to build the [MathFu][] library.
|
||||
* `mathfu/benchmarks`
|
||||
- Each subdirectory under this directory contains a simple benchmark
|
||||
used to measure the performance of different build configurations.
|
||||
* `mathfu/unit_tests`
|
||||
- Each subdirectory under this directory contains a unit test application
|
||||
used to test different components of the library in different build
|
||||
configurations.
|
||||
|
||||
## Building with ndk-build {#mathfu_guide_building_android_building_ndk_build}
|
||||
|
||||
To build a single [Android NDK][] project (without packaging the native
|
||||
component in an [apk][]):
|
||||
|
||||
* Open a command line window.
|
||||
* Go to the directory containing the project to build.
|
||||
* `ndk-build`
|
||||
|
||||
For example, to build the matrix test for the default build configuration
|
||||
without generating an [apk][]:
|
||||
|
||||
~~~{.sh}
|
||||
cd mathfu/unit_tests/matrix_test/default
|
||||
ndk-build
|
||||
~~~
|
||||
|
||||
## Building with fplutil {#mathfu_guide_building_android_building_fplutil}
|
||||
|
||||
To build all [Android NDK][] projects, install and run them on a device:
|
||||
|
||||
* Open a command line window.
|
||||
* Go to the [MathFu][] project directory.
|
||||
* Execute `dependencies/fplutil/bin/build_all_android.py`
|
||||
|
||||
For example:
|
||||
|
||||
~~~{.sh}
|
||||
cd mathfu
|
||||
./dependencies/fplutil/bin/build_all_android.py
|
||||
~~~
|
||||
|
||||
# Installing and Running Applications {#mathfu_guide_building_android_running}
|
||||
|
||||
## Using Eclipse {#mathfu_guide_building_android_eclipse}
|
||||
|
||||
Running a sample requires the [Android Developer Tools][] ([ADT][]) plugin and
|
||||
the [NDK Eclipse plugin][].
|
||||
|
||||
* Build a project using `ndk-build`
|
||||
([see above](@ref mathfu_guide_building_android_building_ndk_build)).
|
||||
* Open [ADT][] Eclipse.
|
||||
* Select "File->Import..." from the menu.
|
||||
* Select "Android > Existing Android Code Into Workspace", and click "Next".
|
||||
* Click the "Browse..." button next to `Root Directory:` and select the
|
||||
project folder (e.g. `mathfu/unit_tests/matrix_test/default`).
|
||||
* Click "Finish". Eclipse imports the project, and displays it in the
|
||||
Package Explorer pane.
|
||||
* Right-click the project, and select "Run->Run As->Android Application"
|
||||
from the menu.
|
||||
* If you do not have a physical device, you must define a virtual one.
|
||||
For details about how to define a virtual device, see [managing avds][].
|
||||
We don’t recommend a virtual device for development.
|
||||
* None of the applications have a visual component so their output is
|
||||
visible via the log ([adb][] logcat).
|
||||
|
||||
## Using fplutil {#mathfu_guide_building_android_fplutil}
|
||||
|
||||
To install and run a single application:
|
||||
|
||||
* Open a command line window.
|
||||
* Go to the directory containing the project to install and run.
|
||||
* Execute `dependencies/fplutil/bin/build_all_android.py` with the `-i`
|
||||
and `-r` options.
|
||||
|
||||
For example:
|
||||
|
||||
~~~{.sh}
|
||||
cd mathfu/unit_tests/matrix_test/default
|
||||
./dependencies/fplutil/bin/build_all_android.py -i -r
|
||||
~~~
|
||||
|
||||
To install and run all applications:
|
||||
|
||||
* Open a command line window.
|
||||
* Go to the [MathFu][] project directory.
|
||||
* Execute `dependencies/fplutil/bin/build_all_android.py` with the `-i`
|
||||
and `-r` options.
|
||||
|
||||
For example:
|
||||
|
||||
~~~{.sh}
|
||||
cd mathfu
|
||||
./dependencies/fplutil/bin/build_all_android.py -i -r
|
||||
~~~
|
||||
|
||||
# Code Generation {#mathfu_guide_building_android_code_generation}
|
||||
|
||||
By default, code is generated for devices that support the `armeabi-v7a`
|
||||
ABI. Alternatively, you can generate a fat `.apk` that includes code for all
|
||||
ABIs. To do so, override APP\_ABI on ndk-build's command line.
|
||||
|
||||
Using `ndk-build`:
|
||||
|
||||
~~~{.sh}
|
||||
ndk-build APP_ABI=all
|
||||
~~~
|
||||
|
||||
Using `fplutil`:
|
||||
~~~{.sh}
|
||||
./dependencies/fplutil/bin/build_all_android.py -f APP_ABI=all
|
||||

Building for Linux {#mathfu_guide_building_linux}
|
||||
==================
|
||||
|
||||
# Version Requirements {#mathfu_guide_building_linux_version}
|
||||
|
||||
Following are the minimum required versions of tools and libraries you
|
||||
need to build [MathFu][] for Android:
|
||||
|
||||
* [CMake][]: 2.8.12.1
|
||||
|
||||
# Prerequisites {#mathfu_guide_building_linux_prerequisites}
|
||||
|
||||
Prior to building, install the following components using the [Linux][]
|
||||
distribution's package manager:
|
||||
|
||||
* [CMake][]. You can also manually install packages from
|
||||
[cmake.org](http://cmake.org).
|
||||
|
||||
For example, on [Ubuntu][]:
|
||||
|
||||
~~~{.sh}
|
||||
sudo apt-get install cmake
|
||||
~~~
|
||||
|
||||
# Building {#mathfu_guide_building_linux_building}
|
||||
|
||||
* Open a command line window.
|
||||
* Go to the [MathFu][] project directory.
|
||||
* Generate [Makefiles][] from the [CMake][] project.
|
||||
* Execute `make` to build the unit tests and benchmarks.
|
||||
|
||||
For example:
|
||||
|
||||
~~~{.sh}
|
||||
cd mathfu
|
||||
cmake -G'Unix Makefiles' .
|
||||
make
|
||||
~~~
|
||||
|
||||
To perform a debug build:
|
||||
|
||||
~~~{.sh}
|
||||
cd mathfu
|
||||
cmake -G'Unix Makefiles' -DCMAKE_BUILD_TYPE=Debug .
|
||||
make
|
||||
~~~
|
||||
|
||||
Build targets can be configured using options exposed in
|
||||
`mathfu/CMakeLists.txt` by using [CMake]'s `-D` option.
|
||||
Build configuration set using the `-D` option is sticky across subsequent
|
||||
builds.
|
||||
|
||||
For example, if a build is performed using:
|
||||
|
||||
~~~{.sh}
|
||||
cd mathfu
|
||||
cmake -G"Unix Makefiles" -DCMAKE_BUILD_TYPE=Debug .
|
||||
make
|
||||
~~~
|
||||
|
||||
to switch to a release build CMAKE_BUILD_TYPE must be explicitly specified:
|
||||
|
||||
~~~{.sh}
|
||||
cd mathfu
|
||||
cmake -G"Unix Makefiles" -DCMAKE_BUILD_TYPE=Release .
|
||||
make
|
||||
~~~
|
||||
|
||||
# Running Applications {#mathfu_guide_building_linux_running}
|
||||
|
||||
Each benchmark binaries are located in the `benchmarks/` directory and
|
||||
unit test binaries are located in the `unit_tests/` directory.
|
||||
|
||||
To run all benchmarks:
|
||||
|
||||
* Open a command line window.
|
||||
* Go to the [MathFu][] project directory.
|
||||
* Run each benchmark binary in the `benchmarks/` directory.
|
||||
|
||||
For example:
|
||||
|
||||
~~~{.sh}
|
||||
cd mathfu
|
||||
for binary in ./benchmarks/*_benchmarks; do ${binary}; done
|
||||
~~~
|
||||
|
||||
To run all unit tests:
|
||||
|
||||
* Open a command line window.
|
||||
* Go to the [MathFu][] project directory.
|
||||
* Run each unit test binary in the `unit_tests/` directory.

Introduction {#mathfu_guide_introduction}
|
||||
============
|
||||
|
||||
# About MathFu {#mathfu_guide_about_mathfu}
|
||||
|
||||
[MathFu][] is a C++ math library developed primarily for games focused on
|
||||
simplicity and efficiency.
|
||||
|
||||
It provides a suite of [vector][], [matrix][] and [quaternion][] classes
|
||||
to perform basic [geometry][] suitable for game developers. This functionality
|
||||
can be used to construct geometry for graphics libraries like [OpenGL][] or
|
||||
perform calculations for animation or physics systems.
|
||||
|
||||
# Prerequisites {#mathfu_guide_prerequisites}
|
||||
|
||||
[MathFu][] is written in C++, you are expected to be experienced in C++
|
||||
programming. [MathFu][] should not be your first C++ programming project! You
|
||||
should be comfortable with compiling, linking, and debugging.
|
||||
|
||||
# About This Guide {#mathfu_guide_about_guide}
|
||||
|
||||
This guide provides an overview of the [MathFu] API, it does *not* cover
|
||||
every aspect of functionality provided by the library. The entire API
|
||||
is documented by the [API reference][]. In addition, the unit tests
|
||||
(under `mathfu/unit_tests`) provide example usage of each class and function
|
||||
in the library.
|
||||
|
||||
# Concepts {#mathfu_guide_concepts}
|
||||
|
||||
The core functionality of [MathFu][] is provided by the following classes:
|
||||
* [Vector](@ref mathfu::Vector)
|
||||
* [Matrix](@ref mathfu::Matrix)
|
||||
* [Quaternion](@ref mathfu::Quaternion)
|
||||
|
||||
Each class is described in the following sections of the guide:
|
||||
* [Vector](@ref mathfu_guide_vectors)
|
||||
- A geometric concept with a magnitude and direction, defined in any
|
||||
dimensional space.
|
||||
* [Matrix](@ref mathfu_guide_matrices)
|
||||
- A set of data organized in rows and columns.
|
||||
[MathFu][] matricies may have any number of rows and columns.
|
||||
* [Quaternion](@ref mathfu_guide_quaternions)
|
||||
- A specific type of four dimensional vector and defines a rotation in
|
||||
three dimensional space.
|
||||
|
||||
In addition, [MathFu][] provides a suite of general math functions and method
|
||||
that make it easier to handle the special requirements of [SIMD][] data types
|
||||
described in the [Utilities](@ref mathfu_guide_utilities) section.
|
||||
|
||||
# Optimization {#mathfu_guide_optimization}
|
||||
|
||||
[MathFu][] is optimized using [SIMD][] instructions (including [NEON][] for
|
||||
[ARM][] and [SSE][] for [x86][] architectures). [SIMD][] optimization is
|
||||
enabled by default based upon the target platform and compiler options used
|
||||
to build a project. In addition, [MathFu][] provides compile time options to
|
||||
modify code generation, see [Build Configurations][] for more details.
|
||||
|
||||
## Supporting Additional Architectures
|
||||
|
||||
[MathFu][]'s [SIMD][] implementation uses [vectorial][] as an abstraction
|
||||
layer for common [SIMD][] instructions and data types. To support additional
|
||||
architectures, contributors can add support for new [SIMD][] instructions and
|
||||
data types to the [vectorial][] project and then modify the code in
|
||||
mathfu/utilities.h to define the macro <code>MATHFU_COMPILE_WITH_SIMD</code>
|
||||
for the new architecture.

Matrices {#mathfu_guide_matrices}
|
||||
========
|
||||
|
||||
Matrices consist of a set of elements (usually floating point or integer
|
||||
scalars) arranged in rows and columns. For more information see
|
||||
[this description](http://en.wikipedia.org/wiki/Matrix_(mathematics))
|
||||
of matrices.
|
||||
|
||||
The [MathFu][] [Matrix][] class is a template declared in
|
||||
[mathfu/matrix.h](@ref mathfu/matrix.h) which has been specialized and
|
||||
optimized for the most regularly used case (floating point elements with
|
||||
4 rows and 4 columns).
|
||||
Implementing [Matrix][] as a template reduces code duplication, provides
|
||||
compile time optimization opportunities through specialization and allows
|
||||
users to use the class with any scalar type.
|
||||
|
||||
# Declaration {#mathfu_guide_matrices_declaration}
|
||||
|
||||
The [Matrix][] class template takes either 2 or 3 arguments in the form:
|
||||
|
||||
* Matrix<type, number_of_rows_and_columns>
|
||||
* Matrix<type, number_of_rows, number_of_columns>
|
||||
|
||||
For example, a floating point 4 row, 4 column (4x4) matrix can be declared
|
||||
using either:
|
||||
|
||||
~~~{.cpp}
|
||||
mathfu::Matrix<float, 4, 4> matrix;
|
||||
~~~
|
||||
|
||||
or:
|
||||
|
||||
~~~{.cpp}
|
||||
mathfu::Matrix<float, 4> matrix;
|
||||
~~~
|
||||
|
||||
To eliminate the need for explicit template instantiation for common matrices,
|
||||
[GLSL][] style `typedef`s are provided in
|
||||
[mathfu/glsl_mappings.h](@ref mathfu/glsl_mappings.h). Using a [GLSL][]
|
||||
style `typedef` a 4x4 floating point matrix variable is declared
|
||||
using the following:
|
||||
|
||||
~~~{.cpp}
|
||||
mathfu::mat4 matrix;
|
||||
~~~
|
||||
|
||||
## Initialization {#mathfu_guide_matrices_initialization}
|
||||
|
||||
For efficiency, [Matrix][] is uninitialized when constructed. Constructors
|
||||
are provided for common matrix sizes that allow initialization on construction.
|
||||
For example, to initialize a 2x2 floating point matrix:
|
||||
|
||||
~~~{.cpp}
|
||||
mathfu::mat2 matrix(1.0f, 2.0f, // column 0
|
||||
3.0f, 4.0f); // column 1
|
||||
~~~
|
||||
|
||||
It's also possible to initialize a [Matrix][] with another instance:
|
||||
|
||||
~~~{.cpp}
|
||||
const mathfu::mat2 matrix1(1.0f, 2.0f, // column 0
|
||||
3.0f, 4.0f); // column 1
|
||||
mathfu::mat2 matrix2(matrix1);
|
||||
~~~
|
||||
|
||||
This can also be achieved with:
|
||||
|
||||
~~~{.cpp}
|
||||
const mathfu::mat2 matrix1(1.0f, 2.0f, // column 0
|
||||
3.0f, 4.0f); // column 1
|
||||
mathfu::mat2 matrix2 = matrix1;
|
||||
~~~
|
||||
|
||||
# Accessors {#mathfu_guide_matrices_accessors}
|
||||
|
||||
[Matrix][] provides an array operator to retrieve individual elements in a
|
||||
flattened array and a parenthesis operator to access an element by row and
|
||||
column index.
|
||||
|
||||
When using the array operator, the [Matrix][] is indexed by rows then columns.
|
||||
For example, a 3x3 matrix will access the following locations:
|
||||
|
||||
Array Index | Column | Row
|
||||
------------|--------|--------
|
||||
0 | 0 | 0
|
||||
1 | 0 | 1
|
||||
2 | 0 | 2
|
||||
3 | 1 | 0
|
||||
4 | 1 | 1
|
||||
5 | 1 | 2
|
||||
6 | 2 | 0
|
||||
7 | 2 | 1
|
||||
8 | 2 | 2
|
||||
|
||||
For example, to access column 1, row 2 of a 3x3 matrix using the array
|
||||
operator, use index "5":
|
||||
|
||||
~~~{.cpp}
|
||||
const mathfu::mat3 matrix(1.0f, 2.0f, 3.0f, // column 0
|
||||
4.0f, 5.0f, 6.0f, // column 1
|
||||
7.0f, 8.0f, 9.0f); // column 2
|
||||
float column1_row2 = matrix[5]; // 6.0f
|
||||
~~~
|
||||
|
||||
The parenthesis operator allows access to an element by specifying the row
|
||||
and column indices directly. For example, to access column 1, row 2 of a
|
||||
3x3 matrix:
|
||||
|
||||
~~~{.cpp}
|
||||
const mathfu::mat3 matrix(1.0f, 2.0f, 3.0f, // column 0
|
||||
4.0f, 5.0f, 6.0f, // column 1
|
||||
7.0f, 8.0f, 9.0f); // column 2
|
||||
float column1_row2 = matrix(2, 1);
|
||||
~~~
|
||||
|
||||
|
||||
## Assignment {#mathfu_guide_matrices_assignment}
|
||||
|
||||
[Matrix][] array and parenthesis operators return a reference to an element
|
||||
which can be modified by the caller.
|
||||
|
||||
For example, to update column 1, row 2 of a 3x3 matrix using the array
|
||||
operator:
|
||||
|
||||
~~~{.cpp}
|
||||
mathfu::mat3 matrix(1.0f, 2.0f, 3.0f, // column 0
|
||||
4.0f, 5.0f, 0.0f, // column 1
|
||||
7.0f, 8.0f, 9.0f); // column 2
|
||||
matrix[5] = 6.0f;
|
||||
~~~
|
||||
|
||||
To update column 1, row 2 of a 3x3 matrix using the parenthesis operator:
|
||||
|
||||
~~~{.cpp}
|
||||
mathfu::mat3 matrix(1.0f, 2.0f, 3.0f, // column 0
|
||||
4.0f, 5.0f, 6.0f, // column 1
|
||||
7.0f, 0.0f, 9.0f); // column 2
|
||||
matrix(2, 1) = 8.0f;
|
||||
~~~
|
||||
|
||||
# Arithmetic {#mathfu_guide_matrices_arithmetic}
|
||||
|
||||
[Matrix][] supports in-place and out-of-place addition and subtraction
|
||||
with other matrices and scalars. Multiplication and division of matrix
|
||||
elements is supported with scalars.
|
||||
|
||||
For example, two matrices can be added together using the following:
|
||||
|
||||
~~~{.cpp}
|
||||
const mathfu::mat2 matrix1(1.0f, 2.0f,
|
||||
3.0f, 4.0f);
|
||||
const mathfu::mat2 matrix2(5.0f, 6.0f,
|
||||
7.0f, 8.0f);
|
||||
mathfu::mat2 matrix3 = matrix1 + matrix2;
|
||||
~~~
|
||||
|
||||
The above preserves the contents of `matrix1` and `matrix2` with the following
|
||||
in `matrix3`:
|
||||
|
||||
6.0f, 8.0f
|
||||
10.0f, 12.0f
|
||||
|
||||
The same can be achieved with an in-place addition which mutates `matrix1`:
|
||||
|
||||
~~~{.cpp}
|
||||
mathfu::mat2 matrix1(1.0f, 2.0f,
|
||||
3.0f, 4.0f);
|
||||
const mathfu::mat2 matrix2(5.0f, 6.0f,
|
||||
7.0f, 8.0f);
|
||||
matrix1 += matrix2;
|
||||
~~~
|
||||
|
||||
Addition with a scalar results in the value being added to all elements.
|
||||
For example:
|
||||
|
||||
~~~{.cpp}
|
||||
mathfu::mat2 matrix1(1.0f, 2.0f,
|
||||
3.0f, 4.0f);
|
||||
matrix1 += 1.0f;
|
||||
~~~
|
||||
|
||||
where `matrix1` contains the following:
|
||||
|
||||
2.0f, 3.0f,
|
||||
4.0f, 5.0f
|
||||
|
||||
Subtraction is similar to addition:
|
||||
|
||||
~~~{.cpp}
|
||||
const mathfu::mat2 matrix1(1.0f, 2.0f,
|
||||
3.0f, 4.0f);
|
||||
const mathfu::mat2 matrix2(5.0f, 6.0f,
|
||||
7.0f, 8.0f);
|
||||
mathfu::mat2 matrix3 = matrix2 - matrix1;
|
||||
~~~
|
||||
|
||||
where `matrix3` contains the following:
|
||||
|
||||
4.0f, 4.0f,
|
||||
4.0f, 4.0f
|
||||
|
||||
Subtraction with a scalar:
|
||||
|
||||
~~~{.cpp}
|
||||
mathfu::mat2 matrix1(1.0f, 2.0f,
|
||||
3.0f, 4.0f);
|
||||
matrix1 -= 1.0f;
|
||||
~~~
|
||||
|
||||
where `matrix1` contains the following:
|
||||
|
||||
0.0f, 1.0f
|
||||
2.0f, 3.0f
|
||||
|
||||
Multiplication with a scalar:
|
||||
|
||||
~~~{.cpp}
|
||||
mathfu::mat2 matrix1(1.0f, 2.0f,
|
||||
3.0f, 4.0f);
|
||||
matrix1 *= 2.0f;
|
||||
~~~
|
||||
|
||||
where `matrix1` contains the following:
|
||||
|
||||
2.0f, 4.0f
|
||||
6.0f, 8.0f
|
||||
|
||||
Division with a scalar:
|
||||
|
||||
~~~{.cpp}
|
||||
mathfu::mat2 matrix1(1.0f, 2.0f,
|
||||
3.0f, 4.0f);
|
||||
matrix1 /= 2.0f;
|
||||
~~~
|
||||
|
||||
where `matrix1` contains the following:
|
||||
|
||||
0.5f, 1.0f
|
||||
1.5f, 2.0f
|
||||
|
||||
# Matrix Operations {#mathfu_guide_matrices_matrix_ops}
|
||||
|
||||
Identity matrices are constructed using
|
||||
[Matrix::Identity](@ref mathfu::Matrix::Identity):
|
||||
|
||||
~~~{.cpp}
|
||||
mathfu::mat2 identity = mathfu::mat2::Identity();
|
||||
~~~
|
||||
|
||||
[Matrix][] supports matrix multiplication using the `* operator`.
|
||||
|
||||
Matrix multiplication is performed using the `* operator`:
|
||||
|
||||
~~~{.cpp}
|
||||
const mathfu::mat2 matrix1(1.0f, 2.0f,
|
||||
3.0f, 4.0f);
|
||||
const mathfu::mat2 matrix2(5.0f, 6.0f,
|
||||
7.0f, 8.0f);
|
||||
mathfu::mat2 matrix3 = matrix1 * matrix2;
|
||||
~~~
|
||||
|
||||
which preserves `matrix1` and `matrix2` while storing the result in
|
||||
`matrix3`:
|
||||
|
||||
23.0f, 31.0f
|
||||
34.0f, 46.0f
|
||||
|
||||
The [inverse](http://en.wikipedia.org/wiki/Invertible_matrix) of a [Matrix][]
|
||||
can be calculated using [Matrix::Inverse](@ref mathfu::Matrix::Inverse):
|
||||
|
||||
~~~{.cpp}
|
||||
const mathfu::mat2 matrix(1.0f, 2.0f,
|
||||
3.0f, 4.0f);
|
||||
const mathfu::mat2 inverse = matrix.Inverse();
|
||||
~~~
|
||||
|
||||
A [Matrix][] multiplied with its' inverse yields the identity matrix:
|
||||
|
||||
~~~{.cpp}
|
||||
const mathfu::mat2 matrix(1.0f, 2.0f,
|
||||
3.0f, 4.0f);
|
||||
const mathfu::mat2 inverse = matrix.Inverse();
|
||||
const mathfu::mat2 identity = matrix * inverse;
|
||||
~~~
|
||||
|
||||
[Matrix][] provides a set of static methods that construct
|
||||
[transformation matrices][]:
|
||||
|
||||
* [Matrix::FromTranslationVector()](@ref mathfu::Matrix::FromTranslationVector)
|
||||
* [Matrix::FromScaleVector()](@ref mathfu::Matrix::FromScaleVector)
|
||||
* [Matrix::RotationX()](@ref mathfu::Matrix::RotationX)
|
||||
* [Matrix::RotationY()](@ref mathfu::Matrix::RotationY)
|
||||
* [Matrix::RotationZ()](@ref mathfu::Matrix::RotationZ)
|
||||
|
||||
Transformation matrices yielded by these operations can be multiplied with
|
||||
vector to translate, scale and rotate. For example, to rotate a 3-dimensional
|
||||
vector around the X axis by PI/2 radians (90 degrees):
|
||||
|
||||
~~~{.cpp}
|
||||
const mathfu::vec3 vector(1.0f, 2.0f, 3.0f);
|
||||
const mathfu::mat3 rotation_around_x(mathfu::mat3::RotationX(M_PI / 2.0f));
|
||||
const mathfu::vec3 rotated_vector = vector * rotation_around_x;
|
||||
~~~
|
||||
|
||||
To scale a vector:
|
||||
|
||||
~~~{.cpp}
|
||||
const mathfu::vec3 vector(1.0f, 2.0f, 3.0f);
|
||||
const mathfu::mat4 scale_by_2(
|
||||
mathfu::mat4::FromScaleVector(mathfu::vec3(2.0f)));
|
||||
const mathfu::vec3 scaled_vector = scale_by_2 * vector;
|
||||
~~~
|
||||
|
||||
In addition, a set of static methods are provided to construct
|
||||
[camera matrices][]:
|
||||
|
||||
* [Matrix::Perspective()](@ref mathfu::Matrix::Perspective)
|
||||
* [Matrix::Ortho()](@ref mathfu::Matrix::Ortho)
|
||||
* [Matrix::LookAt()](@ref mathfu::Matrix::LookAt)
|
||||
|
||||
For example, to construct a perspective matrix:
|
||||
|
||||
~~~{.cpp}
|
||||
const mathfu::mat4 perspective_matrix_ = mathfu::mat4::Perspective(
|
||||
1.0f, 16.0f / 9.0f, 1.0f, 100.0f, -1.0f);
|
||||
~~~
|
||||
|
||||
# Packing {#mathfu_guide_matrices_packing}
|
||||
|
||||
The size of the class can change based upon the [Build Configuration][] so it
|
||||
should *not* be treated like a C style array. To serialize the class to a
|
||||
flat array see [VectorPacked][].
|
||||
|
||||
For example, to pack (store) a [Matrix] to an array of packed vectors:
|
||||
|
||||
~~~{.cpp}
|
||||
mathfu::mat4 matrix(1.0f);
|
||||
mathfu::vec4_packed packed[4];
|
||||
matrix.Pack(packed);
|
||||
~~~
|
||||
|
||||
To unpack an array of packed vectors:
|
||||
|
||||
~~~{.cpp}
|
||||
mathfu::vec4_packed packed[4];
|
||||
mathfu::mat4 matrix(packed);

Quaternions {#mathfu_guide_quaternions}
|
||||
===========
|
||||
|
||||
[Quaternions] provide a representation of a 3-dimensional orientation or
|
||||
rotation. [Quaternions] are especially useful when interpolating between
|
||||
angles to avoid [Gimbal lock][]. For more information, see [this description].
|
||||
|
||||
[MathFu] implements a quaternion as the [Quaternion][] class template which is
|
||||
constructed from one 3-dimensional [Vector][] and scalar component. The
|
||||
[Quaternion][] template is intended to be instanced with `float` or `double`
|
||||
floating point scalar types.
|
||||
|
||||
# Declaration {#mathfu_guide_quaternions_declaration}
|
||||
|
||||
The [Quaternions][] template takes a single argument which specifies the
|
||||
floating point type of each element in the class:
|
||||
|
||||
~~~{.cpp}
|
||||
mathfu::Quaternion<float> quaternion;
|
||||
~~~
|
||||
|
||||
## Initialization {#mathfu_guide_quaternions_initialization}
|
||||
|
||||
For efficiency, [Quaternion][] is uninitialized when constructed. Constructors
|
||||
are provided to initialize the class from a set of scalars, a 3-dimensional
|
||||
[Vector][] and a scalar or another [Quaternion][].
|
||||
|
||||
For example, to initialize a [Quaternion][] using a set of scalars:
|
||||
|
||||
~~~{.cpp}
|
||||
mathfu::Quaternion<float> quaternion(0.71f, 0.0f, 0.71f, 0.0f);
|
||||
~~~
|
||||
|
||||
To initialize a [Quaternion][] from a scalar and 3-dimensional vector
|
||||
component:
|
||||
|
||||
~~~{.cpp}
|
||||
mathfu::Quaternion<float> quaternion(
|
||||
0.50f, mathfu::vec3(0.76f, 0.38f, 0.19f));
|
||||
~~~
|
||||
|
||||
# Accessors {#mathfu_guide_quaternions_accessors}
|
||||
|
||||
[Quaternion][] provides an array operator to retrieve elements of the object.
|
||||
The first index is the scalar component with the remaining 3 indices referring
|
||||
to elements in the vector component.
|
||||
|
||||
~~~{.cpp}
|
||||
const mathfu::Quaternion<float> quaternion(
|
||||
0.50f, mathfu::vec3(0.76f, 0.38f, 0.19f));
|
||||
float s = quaternion[0];
|
||||
float x = quaternion[1];
|
||||
float y = quaternion[2];
|
||||
float z = quaternion[3];
|
||||
~~~
|
||||
|
||||
## Assignment {#mathfu_guide_quaternions_assignment}
|
||||
|
||||
The array operator returns a reference to an element in the [Quaternion][]
|
||||
which can be updated:
|
||||
|
||||
~~~{.cpp}
|
||||
mathfu::Quaternion<float> quaternion;
|
||||
quaternion[0] = 0.5f;
|
||||
quaternion[1] = 0.76f;
|
||||
quaternion[2] = 0.38f;
|
||||
quaternion[3] = 0.19f;
|
||||
~~~
|
||||
|
||||
# Converting Between Representations {#mathfu_guide_quaternions_repr}
|
||||
|
||||
[Quaternion][] provides a number of ways to create a rotation or orientation:
|
||||
|
||||
* [Quaternion::FromAngleAxis()](@ref mathfu::Quaternion::FromAngleAxis)
|
||||
* [Quaternion::FromEulerAngles()](@ref mathfu::Quaternion::FromEulerAngles)
|
||||
* [Quaternion::FromMatrix()](@ref mathfu::Quaternion::FromMatrix)
|
||||
|
||||
For example, to create a [Quaternion][] which rotates PI / 2 radians around
|
||||
the X-axis:
|
||||
|
||||
~~~{.cpp}
|
||||
mathfu::Quaternion<float> quaternion =
|
||||
mathfu::Quaternion<float>::FromAngleAxis(
|
||||
M_PI / 2.0f, mathfu::vec3(1.0f, 0.0f, 0.0f));
|
||||
~~~
|
||||
|
||||
The rotation of PI / 2 radians around the X-axis can also be achieved with:
|
||||
|
||||
~~~{.cpp}
|
||||
mathfu::Quaternion<float> quaternion =
|
||||
mathfu::Quaternion<float>::FromEulerAngles(
|
||||
mathfu::vec3(M_PI / 2.0f, 0.0f, 0.0f));
|
||||
~~~
|
||||
|
||||
Similarly, a quaternion can be constructed from an existing rotation matrix
|
||||
using:
|
||||
|
||||
~~~{.cpp}
|
||||
// Assuming rotation_matrix is an existing matrix.
|
||||
mathfu::Quaternion<float> quaternion =
|
||||
mathfu::Quaternion<float>::FromMatrix(rotation_matrix);
|
||||
~~~
|
||||
|
||||
In addition, methods are provided to calculate an angle / axis pair,
|
||||
Euler angles, or rotation matrix from a [Quaternion][]:
|
||||
|
||||
* [Quaternion::ToAngleAxis()](@ref mathfu::Quaternion::ToAngleAxis)
|
||||
* [Quaternion::ToEulerAngles()](@ref mathfu::Quaternion::ToEulerAngles)
|
||||
* [Quaternion::ToMatrix()](@ref mathfu::Quaternion::ToMatrix)
|
||||
|
||||
For example, to calculate the angle and axis from a [Quaternion][]:
|
||||
|
||||
~~~{.cpp}
|
||||
// Assuming "quaternion" is an existing float quaternion.
|
||||
float angle;
|
||||
mathfu::vec3 axis;
|
||||
quaternion.ToAngleAxis(&angle, &axis);
|
||||
~~~
|
||||
|
||||
To calculate a vector of Euler angles from a [Quaternion][]
|
||||
|
||||
~~~{.cpp}
|
||||
// Assuming "quaternion" is an existing float quaternion.
|
||||
mathfu::vec3 euler_angles = quaternion.ToEulerAngles();
|
||||
~~~
|
||||
|
||||
Finally, to convert a [Quaternion][] to a rotation matrix:
|
||||
|
||||
~~~{.cpp}
|
||||
// Assuming "quaternion" is an existing float quaternion.
|
||||
mathfu::Matrix<float, 3> rotation_matrix = quaternion.ToMatrix();
|
||||
~~~
|
||||
|
||||
# Manipulation {#mathfu_guide_quaternions_manipulation}
|
||||
|
||||
[Quaternion][] objects can be multiplied with each other to combine their
|
||||
rotations.
|
||||
|
||||
For example, if a quaternion that rotates by PI / 2 radians around
|
||||
the X axis is multiplied by itself it will result in a quaternion that rotates
|
||||
by PI radians around the X axis:
|
||||
|
||||
~~~{.cpp}
|
||||
mathfu::Quaternion<float> quaternion_pi_by_2_around_x =
|
||||
mathfu::Quaternion<float>::FromAngleAxis(
|
||||
M_PI / 2.0f, mathfu::vec3(1.0f, 0.0f, 0.0f));
|
||||
mathfu::Quaternion<float> quaternion_pi_around_x =
|
||||
quaternion_pi_by_2_around_x * quaternion_pi_by_2_around_x;
|
||||
~~~
|
||||
|
||||
It's also possible to multiply a [Quaternion][] with a scalar to scale the
|
||||
existing rotation expressed by the object.
|
||||
|
||||
For example, if a quaternion that rotates by PI / 2 radians around
|
||||
the X axis is multiplied by 2 it will result in a quaternion that rotates
|
||||
by PI radians around the X axis:
|
||||
|
||||
~~~{.cpp}
|
||||
mathfu::Quaternion<float> quaternion_pi_by_2_around_x =
|
||||
mathfu::Quaternion<float>::FromAngleAxis(
|
||||
M_PI / 2.0f, mathfu::vec3(1.0f, 0.0f, 0.0f));
|
||||
mathfu::Quaternion<float> quaternion_pi_around_x =
|
||||
quaternion_pi_by_2_around_x * 2.0f;
|
||||
~~~
|
||||
|
||||
In addition, [Quaternion][] provides the ability to perform
|
||||
[spherical linear interpolation][] between two [Quaternion][] objects enabling
|
||||
smooth transitions between rotations while avoiding [Gimbal lock][].
|
||||
|
||||
For example, the rotation half way between two quaternions can be calculated
|
||||
by the following:
|
||||
|
||||
~~~{.cpp}
|
||||
// Assuming "quaternion1" and "quaternion2" represent arbitrary rotations.
|
||||
mathfu::Quaternion<float> quaternion3 =
|
||||
mathfu::Quaternion<float>(quaternion1, quaternion2, 0.5f);
|
||||
~~~
|
||||
|
||||
Finally, the inverse (opposite rotation) of a [Quaternion][] is calculated
|
||||
using [Quaternion::Inverse()](@ref mathfu::Quaternion::Inverse). For example,
|
||||
if a [Quaternion][] represents a rotation PI / 2 radians around the X axis
|
||||
the rotation -PI / 2 degrees around the X axis can be calculated by:
|
||||
|
||||
~~~{.cpp}
|
||||
const mathfu::Quaternion<float> quaternion =
|
||||
mathfu::Quaternion<float>::FromAngleAxis(
|
||||
M_PI / 2.0f, mathfu::vec3(1.0f, 0.0f, 0.0f));
|
||||
mathfu::Quaternion<float> inverse_rotation = quaternion.Inverse();
|
||||
~~~
|
||||
|
||||
# Application {#mathfu_guide_quaternions_application}
|
||||
|
||||
A rotation expressed by a [Quaternion][] is applied to a [Vector][] by
|
||||
multiplying the [Quaternion][] with the [Vector][].
|
||||
|
||||
For example, to rotate a [Vector][] by PI / 2 radians around the X axis:
|
||||
|
||||
~~~{.cpp}
|
||||
const mathfu::vec3 vector(0.0f, 1.0f, 0.0f);
|
||||
const mathfu::Quaternion<float> quaternion =
|
||||
mathfu::Quaternion<float>::FromAngleAxis(
|
||||
M_PI / 2.0f, mathfu::vec3(1.0f, 0.0f, 0.0f));
|
||||
mathfu::vec3 rotated_vector = quaternion * vector;
|
||||
~~~
|
||||
|
||||
When applying rotations to a large number of vectors or points
|
||||
(e.g transforming a set of vertices) it is easier to use
|
||||
[Quaternion::ToMatrix()](@ref mathfu::Quaternion::ToMatrix) to calculate
|
||||
the rotation matrix and apply the same transform to the set of vectors.

Utilities {#mathfu_guide_utilities}
|
||||
=========
|
||||
|
||||
# Memory Allocation {#mathfu_guide_utilities_allocation}
|
||||
|
||||
[MathFu][]'s use of [SIMD][] instructions provides significant performance
|
||||
gains in many use cases. However, some architectures have memory
|
||||
alignment requirements for data used by [SIMD][] operations (e.g [SIMD][]
|
||||
data structures must be 16-byte aligned on x86). Some STL implementations do
|
||||
not respect data type alignment which makes it more difficult to respect the
|
||||
[SIMD][] memory alignment requirements.
|
||||
|
||||
In order to adhere to [SIMD][] alignment requirements, [MathFu][] provides a
|
||||
dynamic memory allocator [AllocateAligned()][] which ensures data is correctly
|
||||
aligned. Memory allocated by [AllocateAligned()][] **must** be deallocated
|
||||
using [FreeAligned()][], for example:
|
||||
|
||||
~~~{.cpp}
|
||||
void *memory = mathfu::AllocateAligned(32);
|
||||
mathfu::FreeAligned(memory);
|
||||
~~~
|
||||
|
||||
The [simd_allocator](@ref mathfu::simd_allocator) class is provided to perform
|
||||
aligned memory allocation with STL classes like std::vector. For example, the
|
||||
following constructs a vector of `vec4` which uses the aligned memory
|
||||
allocator:
|
||||
|
||||
~~~{.cpp}
|
||||
std::vector<vec4, mathfu::simd_allocator<mathfu::vec4>> myvector;
|
||||
~~~
|
||||
|
||||
The aligned memory allocator uses [MATHFU_ALIGNMENT](@ref MATHFU_ALIGNMENT)
|
||||
bytes of additional memory per allocation. If the additional memory usage
|
||||
per allocation is acceptable for an application, the most simple solution
|
||||
is to override the global `new` and `delete` operators by adding
|
||||
[MATHFU_DEFINE_GLOBAL_SIMD_AWARE_NEW_DELETE](@ref MATHFU_DEFINE_GLOBAL_SIMD_AWARE_NEW_DELETE)
|
||||
to the source file containing an application's entry point (e.g `main.cpp`):
|
||||
|
||||
~~~{.cpp}
|
||||
#include "mathfu/utilities.h"
|
||||
|
||||
MATHFU_DEFINE_GLOBAL_SIMD_AWARE_NEW_DELETE
|
||||
|
||||
int main(int argc, char *argv[]) {
|
||||
// The application.
|
||||
return 0;
|
||||
}
|
||||
~~~
|
||||
|
||||
# Miscellaneous Functions {#mathfu_guide_utilities_misc}
|
||||
|
||||
[Clamp](@ref mathfu_Clamp) is used to clamp a value within a specified
|
||||
range. For example:
|
||||
|
||||
~~~{.cpp}
|
||||
float x = 1.0f;
|
||||
z = mathfu::Clamp(x, 1.0f, 2.0f); // z = 1.0
|
||||
z = mathfu::Clamp(x, 1.5f, 2.0f); // z = 1.5
|
||||
z = mathfu::Clamp(x, 0.0f, 0.5f); // z = 0.5
|
||||
~~~
|
||||
|
||||
[Lerp](@ref mathfu_Lerp) linearly interpolates between two values of an
|
||||
arbitrary type in a specified range. For example, an object whose position is
|
||||
specified by a [Vector][] could be moved over a range as time elapses:
|
||||
|
||||
~~~{.cpp}
|
||||
const mathfu::vec2 start(2.0f, 3.0f);
|
||||
const mathfu::vec2 end(10.0f, 0.0f);
|
||||
// Update the position of an object every 100ms.
|
||||
for (float time = 0.0f; time < 1.1f; time += 0.1f) {
|
||||
mathfu::vec2 position = mathfu::Lerp(start, end, time);
|
||||
// Draw object.
|
||||
// Wait 100ms.
|
||||
}
|
||||
~~~
|
||||
|
||||
## Random Number Generation {#mathfu_guide_utilities_random}
|
||||
|
||||
[Random()][] generates pseudo random floating point numbers using `rand()`
|
||||
from the C standard library. For example, the following generates 3 random
|
||||
numbers:
|
||||
|
||||
~~~{.cpp}
|
||||
float value1, value2, value2;
|
||||
value1 = mathfu::Random<float>();
|
||||
value2 = mathfu::Random<float>();
|
||||
value3 = mathfu::Random<float>();
|
||||
~~~
|
||||
|
||||
[Random()][] is used by [RandomRange()](@ref mathfu_RandomRange) to generate
|
||||
a random number within a symmetric range. For example, to generate a random
|
||||
value between -10.0f..10.0f:
|
||||
|
||||
~~~{.cpp}
|
||||
float random_value = mathfu::RandomRange(10.0f);
|
||||
~~~
|
||||
|
||||
Finally, [RandomInRange](@ref mathfu_RandomInRange) can be used to generate
|
||||
a random number within an arbitrary range. For example, to generate a random
|
||||
value between 5.0f..7.0f:
|
||||
|
||||
~~~{.cpp}
|
||||
float random_value = mathfu::RandomInRange(5.0f, 7.0f);
|
||||

Vectors {#mathfu_guide_vectors}
|
||||
=======
|
||||
|
||||
Vectors consist of a set of elements (usually floating point or integer
|
||||
scalars) that are regularly used to describe a point in space or a direction.
|
||||
For more information see this description of
|
||||
[Euclidiean Vectors](http://en.wikipedia.org/wiki/Euclidean_vector).
|
||||
|
||||
The [MathFu][] [Vector][] class is a template declared in
|
||||
[mathfu/vector.h](@ref mathfu/vector.h) which has been specialized and
|
||||
optimized for regularly used cases. Implementing [Vector][] as a template
|
||||
reduces code duplication, provides compile time optimization opportunities
|
||||
through specialization and allows users to use the class with any scalar
|
||||
type.
|
||||
|
||||
# Declaration {#mathfu_guide_vectors_declaration}
|
||||
|
||||
[Vector][] template takes two arguments: the type and number of elements in
|
||||
the [Vector][].
|
||||
|
||||
For example, a 2-dimensional floating point vector variable is declared using
|
||||
the following:
|
||||
|
||||
~~~{.cpp}
|
||||
mathfu::Vector<float, 2> vector;
|
||||
~~~
|
||||
|
||||
To eliminate the need for explicit template instantiation, [GLSL][] style
|
||||
`typedef`s are provided in
|
||||
[mathfu/glsl_mappings.h](@ref mathfu/glsl_mappings.h). Using a [GLSL][]
|
||||
style `typedef` a 2-dimensional floating point vector variable is declared
|
||||
using the following:
|
||||
|
||||
~~~{.cpp}
|
||||
math::vec2 vector;
|
||||
~~~
|
||||
|
||||
## Initialization {#mathfu_guide_vectors_initialization}
|
||||
|
||||
For efficiency, [Vector][] is uninitialized when constructed. Constructors
|
||||
are provided for common vector sizes that allow initialization on construction:
|
||||
|
||||
~~~{.cpp}
|
||||
mathfu::vec2 vector(1.0f, 2.0f);
|
||||
~~~
|
||||
|
||||
It's also possible to initialize a [Vector][] with another instance:
|
||||
|
||||
~~~{.cpp}
|
||||
mathfu::vec2 vector1(1.0f, 2.0f);
|
||||
mathfu::vec2 vector2(vector1);
|
||||
~~~
|
||||
|
||||
This can also be achieved with:
|
||||
|
||||
~~~{.cpp}
|
||||
mathfu::vec2 vector1(1.0f, 2.0f);
|
||||
mathfu::vec2 vector2 = vector1;
|
||||
~~~
|
||||
|
||||
# Accessors {#mathfu_guide_vectors_accessors}
|
||||
|
||||
[Vector][] provides array and [GLSL][] style accessors. For example, to
|
||||
read two elements from a 2-dimensional vector using array accessors:
|
||||
|
||||
~~~{.cpp}
|
||||
const mathfu::vec2 vector(1.0f, 2.0f);
|
||||
float x = vector[0];
|
||||
float y = vector[1];
|
||||
~~~
|
||||
|
||||
It's also possible to read elements from 2, 3 and 4-dimensional vectors using
|
||||
[GLSL][] style accessors:
|
||||
|
||||
~~~{.cpp}
|
||||
const mathfu::vec4 vector(1.0f, 2.0f, 3.0f, 4.0f);
|
||||
float x = vector.x();
|
||||
float y = vector.y();
|
||||
float z = vector.z();
|
||||
float w = vector.w();
|
||||
~~~
|
||||
|
||||
Similar to [GLSL][], [Vector][] provides accessors which allow a subset of
|
||||
elements to be accessed:
|
||||
|
||||
~~~{.cpp}
|
||||
const mathfu::vec3 vector1(1.0f, 2.0f, 3.0f);
|
||||
mathfu::vec3 xy = vector1.xy();
|
||||

|
||||
|
||||
## Assignment {#mathfu_guide_vectors_assignment}
|
||||
|
||||
Individual elements returned by [Vector][]'s array accessors are references
|
||||
that can be assigned values to update the contents of the class:
|
||||
|
||||
~~~{.cpp}
|
||||
mathfu::vec2 vector(1.0f, 2.0f);
|
||||
vector[0] = 3.0f;
|
||||
vector[1] = 4.0f;
|
||||
~~~
|
||||
|
||||
# Arithmetic {#mathfu_guide_vectors_arithmetic}
|
||||
|
||||
[Vector][] supports in-place and out-of-place arithmetic operators
|
||||
(addition, subtraction, multiplication, division) that perform
|
||||
component-wise operations.
|
||||
|
||||
For example, two vectors can be added together using the following:
|
||||
|
||||
~~~{.cpp}
|
||||
const mathfu::vec2 vector1(1.0f, 2.0f), vector2(3.0f, 4.0f);
|
||||
mathfu::vec2 vector3 = vector1 + vector2;
|
||||
~~~
|
||||
|
||||
The above results in the values `(4.0f, 6.0f)` stored in `vector3` while
|
||||
preserving the values of `vector1` and `vector2`.
|
||||
|
||||
The same can be achieved with an in-place addition which mutates `vector1`:
|
||||
|
||||
~~~{.cpp}
|
||||
mathfu::vec2 vector1(1.0f, 2.0f);
|
||||
const mathfu::vec2 vector2(3.0f, 4.0f);
|
||||
vector1 += vector2;
|
||||
~~~
|
||||
|
||||
Subtraction is similar to addition:
|
||||
|
||||
~~~{.cpp}
|
||||
const mathfu::vec2 vector1(4.0f, 6.0f), vector2(3.0f, 4.0f);
|
||||
mathfu::vec2 vector3 = vector2 - vector1;
|
||||
~~~
|
||||
|
||||
Multiplication is performed component-wise, which means that each component
|
||||
is multiplied with the same index component in the other [Vector][] involved
|
||||
in the operation:
|
||||
|
||||
~~~{.cpp}
|
||||
const mathfu::vec2 vector1(2.0f, 0.5f), vector2(3.0f, 10.0f);
|
||||
vector3 = vector1 * vector2;
|
||||
~~~
|
||||
|
||||
The above results in the values `(6.0f, 5.0f)` stored in `vector3` while
|
||||
preserving the values of `vector1` and `vector2`.
|
||||
|
||||
Similar to the other operators, multiplication can be performed in place:
|
||||
|
||||
~~~{.cpp}
|
||||
mathfu::vec2 vector1(2.0f, 0.5f);
|
||||
const mathfu::vec2 vector2(3.0f, 10.0f);
|
||||
vector1 *= vector2;
|
||||
~~~
|
||||
|
||||
Division is also a component-wise operation:
|
||||
|
||||
~~~{.cpp}
|
||||
const mathfu::vec2 vector1(4.0f, 4.0f), vector2(2.0f, 4.0f);
|
||||
vector3 = vector1 / vector2;
|
||||
~~~
|
||||
|
||||
The above results in the values `(2.0f, 1.0f)` stored in `vector3` while
|
||||
preserving the values of `vector1` and `vector2`.
|
||||
|
||||
# Constants {#mathfu_guide_vectors_constants}
|
||||
|
||||
Commonly used constants are provided by
|
||||
[mathfu/constants.h](@ref mathfu/constants.h). These values eliminate the need
|
||||
to construct [Vector][] objects for common values like cardinal axes.
|
||||
|
||||
For example, the following initializes a 2-dimensional vector with the X-axis:
|
||||
|
||||
~~~{.cpp}
|
||||
const mathfu::vec2 vector = mathfu::kAxisX2f;
|
||||
~~~
|
||||
|
||||
# Geometric Operations {#mathfu_guide_vectors_geometric}
|
||||
|
||||
[Vector][] also provides functions for commonly used geometric operations
|
||||
that are utilized by graphics and games developers.
|
||||
|
||||
For example, the length of a [Vector][] is calculated using
|
||||
[Length()](@ref mathfu::Vector::Length):
|
||||
|
||||
~~~{.cpp}
|
||||
const mathfu::vec2 vector(3.0f, 4.0f);
|
||||
float length = vector.Length();
|
||||
~~~
|
||||
|
||||
The projection of one [Vector][] onto another (dot product) can be calculated
|
||||
using [DotProduct()](@ref mathfu::Vector::DotProduct). For example, the
|
||||
following calculates the projection of a vector onto the X-axis:
|
||||
|
||||
~~~{.cpp}
|
||||
float projection = mathfu::vec2::DotProduct(mathfu::vec2(5.0f, 2.0f),
|
||||
mathfu::kAxisX2f);
|
||||
~~~
|
||||
|
||||
It's possible to normalize (scale to a length of 1) a vector in-place using
|
||||
[Normalize()](@ref mathfu::Vector::Normalize) or out-of-place using
|
||||
[Normalized()](@ref mathfu::Vector::Normalized). For example, the following
|
||||
normalizes the vector in-place:
|
||||
|
||||
~~~{.cpp}
|
||||
mathfu::vec2 vector(3.0f, 4.0f);
|
||||
vector.Normalize();
|
||||
~~~
|
||||
|
||||
The cross product of two 3-dimensional [Vectors][] (the vector perpendicular
|
||||
to two vectors) can be calculated using
|
||||
[CrossProduct()](@ref mathfu::Vector::CrossProduct), for example:
|
||||
|
||||
~~~{.cpp}
|
||||
mathfu::vec3 zaxis = mathfu::vec3::CrossProduct(mathfu::kAxisX3f,
|
||||
mathfu::kAxisY3f);
|
||||
~~~
|
||||
|
||||
Alternatively, to create three points and compute the normal of the plane
|
||||
defined by the points use:
|
||||
|
||||
~~~{.cpp}
|
||||
mathfu::vec3 point1(0.5f, 0.4f, 0.1f);
|
||||
mathfu::vec3 point2(0.4f, 0.9f, 0.1f);
|
||||
mathfu::vec3 point3(0.1f, 0.8f, 0.6f);
|
||||
|
||||
mathfu::vec3 vector1 = point2 - point1;
|
||||
mathfu::vec3 vector2 = point3 - point1;
|
||||
|
||||
mathfu::vec3 normal = Vector<float, 3>::CrossProduct(vector2, vector1);
|
||||
~~~
|
||||
|
||||
# Other Operations {#mathfu_guide_vectors_other}
|
||||
|
||||
In addition, to basic arithmetic and geometric operations, [Vector][] also
|
||||
implements functions to perform the following:
|
||||
|
||||
* [Lerp](@ref mathfu::Vector::Lerp) to linearly interpolate between two
|
||||
vectors.
|
||||
* [RandomInRange](@ref mathfu::Vector::RandomInRange) to generate a vector
|
||||
with random value for elements.
|
||||
|
||||
# Packing {#mathfu_guide_vectors_packing}
|
||||
|
||||
The size of the class can change based upon the [Build Configuration][] so it
|
||||
should *not* be treated like a C style array. To serialize the class to a
|
||||
flat array see [VectorPacked](@ref mathfu::VectorPacked).
|
||||
|
||||
For example, to pack (store) an unpacked to packed vector:
|
||||
|
||||
~~~{.cpp}
|
||||
mathfu::vec3 vector(3.0f, 2.0f, 1.0f);
|
||||
mathfu::vec3_packed packed = vector;
|
||||
~~~
|
||||
|
||||
Since [VectorPacked][] is plain-old-data (POD) it can be cast to an array
|
||||
of elements of the same type used by the [Vector][] so it's possible to use
|
||||
an array of [VectorPacked][] data structures to contiguous arrays of data like
|
||||
vertex buffers.
|
||||
|
||||
Similarly, [VectorPacked][] can be used to deserialize (load) data into
|
||||
[Vector][]:
|
||||
|
||||
~~~{.cpp}
|
||||
VectorPacked<float, 3> packed = { 3, 2, 1 };
|
||||
Vector<float, 3> vector(packed);
|
||||

MathFu Version 1.1.0 {#mathfu_readme}
|
||||
====================
|
||||
|
||||
MathFu is a C++ math library developed primarily for games focused on
|
||||
simplicity and efficiency.
|
||||
|
||||
It provides a suite of [vector][], [matrix][] and [quaternion][] classes
|
||||
to perform basic [geometry][] suitable for game developers. This functionality
|
||||
can be used to construct geometry for graphics libraries like [OpenGL][] or
|
||||
perform calculations for animation or physics systems.
|
||||
|
||||
The library is written in portable C++ with [SIMD][] compiler intrinsics and
|
||||
has been tested on the following platforms:
|
||||
|
||||
* [Android][]
|
||||
* [Linux][] (x86_64)
|
||||
* [OS X][]
|
||||
* [Windows][]
|
||||
|
||||
Go to our [landing page][] to browse our documentation and see some examples.
|
||||
|
||||
* Discuss MathFu with other developers and users on the
|
||||
[MathFu Google Group][].
|
||||
* File issues on the [MathFu Issues Tracker][]
|
||||
* Post your questions to [stackoverflow.com][] with a mention of
|
||||
**mathfu**.
|
||||
|
||||
**Important**: MathFu uses submodules to reference other components it depends
|
||||
upon so download the source using:
|
||||
|
||||
git clone --recursive https://github.com/google/mathfu.git
|
||||
|
||||
To contribute to this project see [CONTRIBUTING][].
|
||||
|
||||
For applications on Google Play that integrate this tool, usage is tracked.
|
||||
This tracking is done automatically using the embedded version string
|
||||
(kMathFuVersionString), and helps us continue to optimize it. Aside from
|
||||
consuming a few extra bytes in your application binary, it shouldn't affect
|
||||
your application at all. We use this information to let us know if MathFu
|
||||
is useful and if we should continue to invest in it. Since this is open
|
||||
source, you are free to remove the version string but we would appreciate if
|
||||
you would leave it in.
