- Adding FarStencilTables and FarStencilTablesFactory classes
- Adding Osd EvalStencil context & controllers for CPU, OMP and TBB backends
- Adding the code example glStencilViewer
- Adding reST documentation
- Changing version to 2.2.0_dev
- Fix HbrMesh::Unrefine function
- Fix "CanEval" function in OsdVertexBufferDescriptor
Note 0: there is no stencil support for hierarchical edits
Note 1: there is no support for face-varying data stencils yet
Note 2: the current stencil factory is lazy but the caching system is not re-entrant
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...
