- removed overloads in favor of direct stencil table access and update
- updated precision related assertions with clearer condition
- updated far/tutorial_6 to use template stencil table access
- updated far/tutorial_9 to use conventional stencil table access
- added tutorial/far/tutorial_9 with source for new tutorial
- updated tutorial/CMakeLists.txt to deal with header path issue:
- inclusion of code from regression/common required extension

- suppress generation of Varying patches and/or their local point stencils
- added suppression of Varying patches to far/tutorial_6
Read all comments and made corrections to files that aren't part of
OpenSubdiv itself but are packaged with it.
Commandline output of glPtexViewer is affected. Otherwise no functional
changes.
Adaptive refinement will only produce levels of refinement which are
actually needed even if the client specifies a greater max isolation level.
This change fixes the loop control used for primvar interpolation to
interpolate only levels which exist in the refinement.
Far no longer supports this method, so the existing functions were pure noise.
Hbr, however still requires it, so there are still a couple instances of it in
the hbr tutorial files.
- moved TopologyRefiner out of the RefinerFactoryBase into Far
- moved implementation of its Factory<MESH> to far/topologyDescriptor.*
- updated examples and tutorials (no more references to FactoryBase)
- removed all of the multi-level Interpolate...() methods taking T*, U*
- made all single-level methods consistent wrt usage of T&, U&
- replaced usage in regressions, tutorials and examples
- additional minor improvements to far/tutorials
To encapsulate endcap functions from public API, add methods to
tell the number of patch points needed (GetNumLocalPoints()) and
to compute those patch points as a result of change of basis from
the refined vertices (ComputeLocalPointValues()).
ComputeLocalPointValues takes contiguous source data of all levels
including level0 control vertices.
- removed AddVaryingWithWeight from Far::PrimvarRefiner interpolation
- removed Far::StencilBuilder dependencies on varying
- updated Far::StencilTableFactory use of StencilBuilder constructor
- updated far/tutorial_2 to use vertex colors vs varying (for now)
- added TopologyRefiner base level modifiers to TopologyRefinerFactoryBase
- removed old modifiers from TopologyRefiner (unused by anything else)
- updated existing Factory<MESH> definitions to use new methods
- created new class Far::PrimvarRefiner with interpolation methods
- removed interpolation and limit methods from Far::TopologyRefiner
- replaced internal usage in Far::StencilTableFactory
- replaced usage in regressions, tutorials and examples
- replaced Evaluate() with EvaluateBasis() in far/tutorial_6
- commented out use of EvaluateFaceVarying() in examples/farViewer
- face-varying patches are work in progress
- rename "Regular end cap" to "BSplineBasis end cap"
- revert templating and add EndCapType into PatchTablesFactory::Options.
- make EndCapFactories internal in PatchTablesFactory.
- move end cap stencils into PatchTables, keep them relative to the max level.
- add a utility StencilTablesFactory::AppendEndCapStencilTables to splice and factorize endcap stencil tables.
Remove the ptex-specific code from the Far::TopologyRefiner and instead provide it in a separate class Far::PtexIndices. Clients who need to use the Ptex API need to first build a Far::PtexIndices object by providing it with a refiner.
This has the advantage of keeping the API on the TopologyRefiner a little cleaner. The ptex methods were const but were mutating state with const_casts. The new mechanism still achieves the same lazy initialization behavior by forcing clients to instantiate them exactly when needed.
A disadvantage of this approach is that the PatchTablesFactory creates its own PtexIndices and throws it out after the patch tables are created. This is great if you're never going to need the ptex indices again, but not so great if you will need them again.
- extend Far::PatchTables data structures & interfaces to store requisite
information for channels of face-varying bi-cubic patches
- implement gather function in Far::PatchTablesFactory to populate face-varying
channels with adaptive patches
- extend accessor interface in Vtr::Level
- propagate code fall-out throughout OpenSubdiv code base, examples & tutorials
- extend vtrViewer code to visualize tessellated bi-cubic face-varying patches
