In example code, GLUT has been replaced with GLFW so that glViewer/ptexViewer can run on OSX (10.7 or later).
OSX note: still have some problem with clang, may need to explicitly specify gcc on cmake cmdline
-DCMAKE_CXX_COMPILE=/usr/bin/g++
fixes#98
- remove the GL error check in cudaGLVertexBuffer :
* unrelated GL errors left on the stack were triggering erroneous
vertexBuffer allocation errors
* we should not be checking for GL errors here anyway (as most other
buffer allocations aren't checked either)
- add some pointer checking in the GL / D3D drawContexts in case the
vertexBuffer pointers passed are NULL
- add some additional typedefs in OsdError to report some of the new
CUDA / GL related errors
- still need to change these changes with other compilers (MSVC / clang...)
- had to add a -Wno-invalid-offsetof for GCC (still need to test w/ other compilers) : apparently gcc 4.4 is somewhat incorrect in tagging our templated class as POD.
- had to change fvarData.h to initialize bitfields to 0 as gcc generates truncated int warnings when trying to initialize 31 bits to -1
- in mesh.h replaced original tbb::concurrent_vector with std::vector until a better solution can be found
Fixes#93
This avoids adaptive tessellation artifacts near silhouette edges
by using the projected diameter of an edge's bounding sphere
rather than the length of the projected edge itself.
There is a nice writeup of this by Bryan Dudash of NVIDIA at:
https://developer.nvidia.com/content/dynamic-hardware-tessellation-basics
- [Feature Adaptive GPU Rendering of Catmull-Clark Surfaces](http://research.microsoft.com/en-us/um/people/cloop/tog2012.pdf).
- New API architecture : we are planning to lock on to this new framework as the basis for backward compatibility, which we will enforce from Release 1.0 onward. Subsequent releases of OpenSubdiv should not break client code.
- DirectX 11 support
- and much more...
There seems to be a bug in clang: despite the fact that FarMeshFactory is
declared to be a friend class from FarSubdivisionTables, clang protests that
VertexKernelBatch is not accessable.
This hack adds an #ifdef __clang__ block to make that structure public and keep
Far compiling under OSX.
- All data representation classes are now single-templated for a vertex class 'U'
- All constructors / instancing code has been moved into "Factory" functions that are dual-templated
for two vertex classes <class T, class U=T>. This allows hbr specialization with a placeholder
vertex flass 'T' for faster analysis without paying interpolation costs, while far can still specialize
a fully implemented vertex class 'U' with full subdivision functionality.
- Some preliminary clean-up work on FarVertexEditTables with the addition of a FarVertexEdit class
as a replacement for the former HbrVertedEdit which was introducing back dependencies on hbr. The
implementation is very lightweight. Some slight renaming / cleanup of the code, with some more to
be done.
- there are no more dependencies on hbr (not even #include) from far's data structure !
Notes :
- the FarDispatcher mechanism has become somewhat awkward and should be re-evaluated when refactoring osd.
- the "Factory" pattern survives this round of refactoring until we can find something better.
Closes#34
output iterators instead of std::vector - eases prman integration
for cases where std::list makes more sense.
Block allocate face children array in common case (<= 4 children).
Other, minor consistency edits.
mutex class with Lock / Unlock public functions.
- remove Mutex implementation from Hbr (and revert to original PRman code)
- provide a Mutex class stub in osd
- add some forward declarations in OsdMesh to limit some of the mutex spills
- #include <osd/mutex.h> where needed (little hackish until we can refactor
some of far better)
- remove ILM_BASE from some CMakeLists
Closes#48
where it can cause havoc downstream, and move vertexBuffers into the cpp
file to avoid gl.h inclusion and to fix dynamic cast issues. These were
found during Presto integration.
