- Added support for OSX CI builds and tests
- Cleaned up build scripts and moved to $ROOT/build_scripts
- On Linux: moved to trusty distro
- On Linux: enabled OpenMP, TBB and PTex build options
- On Linux: install and setup xvfb with newer mesa drivers to run our GL tests
- On Linux: enable GL tests
Read all comments and made corrections to files that aren't part of
OpenSubdiv itself but are packaged with it.
Commandline output of glPtexViewer is affected. Otherwise no functional
changes.
Also removed the remaining Maya dependencies. These
were most useful during the early days of OpenSubdiv.
Now OpenSubdiv has been integrated directly into Maya
and these examples serve little purpose.
- update GUI to match more closely glPtexViewer
- added pipeline stats query for number of triangles tesselated
- matched CPU / GPU compute timers
- added obj animation
- fixed near / far clip planes
- fix build compiling & linking to accomodate recent code churn in Ptex
- fix FindPTex.cmake module to correctly extract version number
- fix dxPtexViewer & glPtexViewer source to compile with new Ptex namespace changes
- add alpha channel padding function to ptexMipmapLoader as a workaround to the absence of 3-channel DXGI formats
- mirror ptex memory limit function from glPtexViewer to dxPtexViewer
stb - potential use of uninitialized variable (this may have been safe)
farViewer - unused variable
patchTableFactory - _channelIndices potentially used uninitialized
FVarLevel - valueIndexInFace0 potentially used used uninitialized (was safe)
- the framebuffer class in examples/common is unstable in certain drivers.
removing offscreen rendering for now.
- move screenshot function to GLUtils.
- fix vertex attrib binding bug (not showing control mesh on osx)
- add GLControlMeshDisplay and D3D11ControlMeshDisplay into
examples/common
- delete all drawCageEdges/drawCageVertices from viewers and
use ControlMeshDisplay class
Adding command line options to glViewer to make it easy
to control the requested GL version and profile. While
it is only enabled for glViewer in this change, it will
be easy to extend to all our example viewers. The new
command line options are:
-glCoreProfile on|off
-glForwardCompat on|off
-glVersion M.n
It appears the behavior of the version hint is operating system
(and perhaps driver) specific. On OSX the version hint is a
minimum version, but on Linux you get exactly the version
requested.
The GLFW FAQ seems to suggest that any driver not supporting
ARB_compatibility may need the hint.
s
- Make sure to declare usage of the include files if GLFW is found
- When GLFW is found and is compiled into examples/common, we need to
unfortunately link it into dxViewer. Hopefully we can refactor common
so that this won't be necessary in the future.
The GLFW context version hint is a minimum version, not maximum version so
requesting 4.4 and then falling back to lower versions doesn't make sense.
This change sets the minimum version to 3.2 and attempts to standardize this
across all example apps.
Also print the maximum supported GL version along with the context version
at startup.
We will need to find a solution for Ignacio's older setup, but this at least
fixes the other fallout.
* Use glewIsSupported instead of glewGetExtension
* Convert tabs to spaces
* Remove GLEW static caching (they only get called once)
All examples, regression tests and tutorials directly looked into
opensubdiv source directory to grab the header files. This is somewhat
convenient during development but they can mistakenly access private
header files.
With this change, when OPENSUBDIV_INCLUDE_DIR is given to cmake,
it will be used as an include search path to build examples etc.
Otherwise it follows the same behavior as before.
Also replaces include references to the files in regression dir
to be relative, and cleanups some copy-paste patterns.
In osd layer, we use GLPatchTable (D3D11PatchTable) as a
device-specific representation of FarPatchTables instead of
DrawContext. GLPatchTable may be used not only for drawing
but also for GPU eval APIs (not yet supported though.
We may add CudaPatchTable etc as needed).
The legacy gregory patch drawing buffers are carved out to
the separate class, named GLLegacyGregoryPatchTable.
Also face-varying data are split into client side for now, until
we add new and more robust face-varying drawing structure
(scheduled at 3.1 release)
Tentatively replicate PatchArray structure in GLPatchTables. It will
be revised in the upcoming change.
Shifting hard-coded SRV locations of legacy gregory buffers in HLSL shaders.
As a preparation for retiring DrawContext, move SupportsAdaptiveTessellation
method to examples/common/glUtils, which is renamed and namespaced
from gl_common.{cpp,h} to be consistent to other files.
Same renamings applied to other example files.
Remove DrawRegistry from osd layer and put a simple shader caching
utility into examples/common. osd layer only provides patch shader
snippet and let client configure and compile the code. Clients also
maintain the lifetime of shader object, which is preferable for the
actual application integration.
update all examples to use the new scheme.
