The cmake config export paths are now more consistent
with other vfx platform projects.
The target names are now more consistent with existing
opensubdiv static and dynamic library names.
This simplifies build dependencies when cross-compiling
or when building multi-architecture binaries.
For backward compatibility with earlier releases, the compiled
C++ version of this tool is used when no Python interpreter is found.
This adds support for the standard global option
BUILD_SHARED_LIBS
to select whether to build shared libraries.
Note that building shared DLL libraries is still
not yet supported on Windows.
At build time, the preprocessor symbols: OSD_USES_GLEW or
OSD_USES_INTERNAL_GLAPILOADER determine the GL API loader
that will be used by the OSD library.
This introduces an internal glLoader library which allows
most of the implementation to be agnostic about the
implementation of the GL loading library. Specifically,
this removes references to the GLEW headers and libraries
from the rest of the source code and build system.
The example code that uses Metal forces C++11 features, therefore
we have to turn it on clang so that we can enable the building of
compatible code that can be used by Metal and GL at the same time.
As mentioned in issue #997, OpenSubdiv still uses CUDA functionality
that is being deprecated. When warnings are treated as errors, this
can make OpenSubdiv fail to compile. For now, we turn off these
deprecation warnings until we can address them.
- changed the main OPENSUBDIV_INCLUDE_DIR to exclude ./opensubdiv
- updated CMakeLists.txt files in non-examples to use only this path
- updated CMakeLists.txt files in examples to append ./opensubdiv to path
- updated source in regression/common to use #include <opensubdiv/...>
- updated source in examples/common to use #include <opensubdiv/...>
- deferred source in examples to be updated on a case-by-case basis
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
