- FarKernelBatch becomes a class w/ accessors
- split the FarKernelBatchFactory to its own header file
- add doxy doc
- propagate fallout to the rest of the code base
a new function is added to avoid confusion.
-GetNumVertices() returns number of vertices
-GetNumVerticesTotal() returns total number of vertices includins number of lower levels.
#closes 156
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)
- [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.
