Noticed a few typos when browsing comments. Proceeded with a "manual
spell check", reading all comments and tweaking spelling, grammar,
punctuation.
Didn't bother with Hbr library.
Comments only, no functional changes.
Previously, glew was forced to static linkage on windows, even when
dynamic Glew libraries were linked which would result in linker errors.
In this change, static glew libraries are detected by looking for the "s"
suffix convention on the library (though, maybe this should be handled in
the FindGlew module).
The symbol OPENSUBDIV_GREGORY_EVAL_TRUE_DERIVATIVES
determines the method used to compute derivative weights
for Gregory basis patches.
Setting this symbol during CMake configuration (and
hence during C++ and shader compilation) will enable
the use of true derivative weights.
The default behavior is to use a simpler approximation
for consistency with earlier releases.
Recent CUDA SDKs no longer support the "compute_11"
gpu architecture. We now fallback to "compute_20"
instead for newer SDK versions. Additionally, this
behavior can be overriden using the new CMake list
variable OSD_CUDA_NVCC_FLAGS so that it is easier
for clients to target newer architectures and specify
additional arguments.
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.
- 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
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.
- resolves DX-CL interop functions in Osd::ClD3D11VertexBuffer.
- enable CL kernels in DX build.
- more cleanup in test harnesses, adding D3D11 initializations into DeviceContext.
- add new defines OPENSUBDIV_HAS_OPENGL and OPENSUBDIV_HAS_DX for convenience.
- Upped minimum required version of docutils from 0.6 to 0.9.
- Fixed link to pygments in build documentation
- Fixed link to doxygen in build documentation
Sync'ing the 'dev' branch with the 'feature_3.0dev' branch at commit 68c6d11fc36761ae1a5e6cdc3457be16f2e9704a
The branch 'feature_3.0dev' is now locked and preserved for historical purposes.
* assembler kernels are based on the C implementation in neonKernel.cpp
* enable assembler kernel functions in neonComputeController.cpp with #define USE_ASM_KERNELS 1
If the system has CLEW installed (which is detected by recently
added FindCLEW routines) then OpenSubduv would be compiled against
this library.
It makes binaries and libraries more portable across the systems,
so it's possible to run the same binary on systems with and without
OpenCL SDK installed.
The most annoying part of the change is updating examples to load
OpenCL libraries, but ideally code around controllers and interface
creation is to be de-duplicated anyway.
Based on the pull request #303 from Martijn Berger
It solves the issues when one generated makefiles with
some of the custom command line options passed to CMake
and then modified the CMake file. This used to forget
about settings passed via command line.
Now it's no longer required to re-run CMake with all
custom options every time CMakeLists.txt files are
modified.
- icc asserts out because of the length of rpath, so we are temporarily removing the elements
that aren't defined until chrpath is invoked by cmake (this means installed executables are
missing paths to the built OSD dsos)
- comment out some of the warnings for missing packages if they were deliberately turned off
* added the numVertexElements argument to Osd*DrawContext::Create, which is used to initialize the patch arrays when calling OsdDrawContext::ConvertPatchArrays
* removed the unused level argument from Osd*DrawContext::_initialize
* maintenance work on CL/D3D11 bindings to get them to compile
