This is a new implementation of the stencil table construction algorithm found
in protoStencil.h. In local tests with production assets, the new algorithm is
~25% faster and significantly more stable, in terms of average performance
In one asset test, generating stencils for level 10 adaptive refinement of
BuzzLightyear was reduced from 18s to 13s.
- it takes number and pointer for the input PatchCoords.
- add derivative evaluations.
- enhance glEvalLimit example to see the derivative evaluation works.
Cleaned up the Legacy Gregory shader source by accessing buffer
data through helper functions.
Switched to performing tessellation in untransformed (object) space.
this change fixes a crash when selecting catmark_hole_test1
in glStencilViewer. If there's a hole limit stencils may not
be found for given limit location, resulting invalid stencil
entries.
- changed Vtr::LocalIndex to 16-bit integer from 8-bit
- added test shapes including valence 360 vertices
- disabled new shapes in far/regression until improved accuracy accepted
PatchTables no longer needs to friend EndCapLegacyGregoryPatchFactory.
Instead we now make the patch table factory pass in the data that needs
to be updated directly to EndCapLegacyGregoryPatchFactory.
- replaced Evaluate() with EvaluateBasis() in far/tutorial_6
- commented out use of EvaluateFaceVarying() in examples/farViewer
- face-varying patches are work in progress
In osd layer, we use GLPatchTable (D3D11PatchTable) as a
device-specific representation of FarPatchTables instead of
DrawContext. GLPatchTable may be used not only for drawing
but also for GPU eval APIs (not yet supported though.
We may add CudaPatchTable etc as needed).
The legacy gregory patch drawing buffers are carved out to
the separate class, named GLLegacyGregoryPatchTable.
Also face-varying data are split into client side for now, until
we add new and more robust face-varying drawing structure
(scheduled at 3.1 release)
Tentatively replicate PatchArray structure in GLPatchTables. It will
be revised in the upcoming change.
Shifting hard-coded SRV locations of legacy gregory buffers in HLSL shaders.
- changes completely deprecate AddWithWeight(T, float, float, float)
- added new EvaluateBasis() method to PatchTables
- replaced usage of old Evaluate...<T,U>() methods with EvaluateBasis()
- removed old Evaluate...<T,U>() methods
- removed now unused Interpolate...<T,U>() functions in far/interpolate.h
- moved low-level basis code from far/interpolate.* to patchBasis.*
