Also improved the doxygen target and made the doxy build "quiet".
fixes#154
- replace ptex indexing with the FarPtexCoord structure as a way to pass per-patch
ptex data to the shaders.
We are replacing a vector<int> arranged as :
int[0] : ptex face index
int[1] : (u,v) as 16 bits encoding the log2 coordinate of the top left corner
Instead we are now using a struct arranged as :
int[0] : ptex face index
int[1] : is a bit-field containing u,v, rotation, depth and non-quad
The u,v coordinates have been reduced to 10 bits instead of 16, which still
gives us a lot of margin.
- Replace OsdVertexBufferDescriptor with something more adequate for general
primvar representation (this name will probably eventually change...)
- Improve OsdPatchDescriptor
- add a "loop" boolean (true if the patch is of loop type)
- add a GetPatchSize() accessor
- OsdPatchArray :
- remove some redundant elements (still more to do there)
- Fix all shader / examples / regressions & stuff to make this all work.
fixes#143
2 client APIs are changed.
- VertexBuffer::UpdateData() takes start vertex offset
- ComputeController::Refine() takes FarKernelBatchVector
Also, ComputeContext no longer holds farmesh.
Client can free farmesh after OsdComputeContext is created.
(but still need FarKernelBatchVector to apply subdivision kernels)
Now a ComputeController is passed as an
argument to OsdMesh::Create(). This is
a better match to the underlying object
model and can be much more efficient for
compute controllers that have expensive
resources, e.g. compiled shader kernels.
Fixes#103
- consolidate cmake compile flags
- turn on -Wall
- suppress hidden overloaded function warning when using Clang
(part of it is bug, part of it will require code refactoring
on our end)
- add support for Maya 2013.5 for windows in cmake module
- clean up some glew includes which break builds with MSVC Express
& Windows SDK
- move the bitmap for font_image into a compiled object
- remove some unused variables and other minor warnings
Note : this is a checkpoint, there are still a few more warnings to clean up...
fixes#96
- cmake should now be better at finding Maya installations on OSX automatically
- various dependency fixes for Maya plugins
- first pass at some code fixes to build Maya plugins on OSX
this not the final word on this : just like glutViewer, we will need a "_compat" version of these plugins
fixes#95
- [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...
- 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
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.
kernel, call OsdKernelDispatcher::Factory::Register() and keep the integer
result value as kernel handle.
Attempted to elimiate registering function from client code, but currently
disabled (in kernelDispatcher.cpp) because of Maya plugin doesn't work with cuda
kernel.
glutViewer creates kernel menu dynamically according to linked kernels.
Fix a bug of maya plugin crashes.
Closes#14
- use find_package(OpenMP) to test that the compiler supports OMP
(looks like the "express" versions of MSVC do not)
- if not available, make sure that osd does not register those
compute kernels (but does register the CPU standalone ones)
- similar refinements on other dependencies (Maya, CUDA) where
the build "opts in" depending on which libs are found.
some CMakeLists still need more cleanup...
Closes#9
