- updated the edge-only and edge-corner shapes consistent with Catmark
- moved the existing triangulated cube to loop_cube_asymmetric
- added new loop_cube with symmetric triangulation and limit surface
- added semi-sharp and inf-sharp variations of cube and icosahedron
- added shapes with extra-ordinary interior and boundary vertices
- added shapes with face-varying features similar to Catmark
Previously, the glEvalLimitViewer was hard coded to
use only adaptive refinement, but this change demostrates
how to evaluate patch locations on the linear patches
resulting from a uniform refinement.
By default, in a patch table created from a uniform refinement,
the patch indices for vertex patches account for base level indices,
while the patch indices for face-varying patches do not account for base
level indices.
This change also updates the example to set the patch table factory options
so that both kinds of patch indices account for base level indices.
- stripped StencilTableHandler down to simpler StencilTablePtr wrapper
- replaced old convenience methods with direct conditions in PatchTable
- created new private template methods to simplify PatchTableBuilder
- corrected stencil estimates according to the interpolation mode
- removed the added error checking for the tables provided
- use uniform vertex patches when varying interpolation specified
- added internal option to generate polygons vs patches when uniform
- updated PatchTableFactory to identify patches at a specified level
- renamed internal symbols to remove obsolete references to Adaptive
- updated Catmark builder to use edge-point boundary tags like Loop
- fixed Gregory face point reliance on boundary isolation assumptions
- added comments to PatchBuilder base class to clarify intention and usage
This updates the patch basis evaluation functions in Osd
to match recent changes to far/patchBasis.
This also exposes a common facility for dealing with PatchCoord,
PatchArray, and PatchParam. These are exposed as global functions
operating on struct data, since C++ style class methods are not
supported by all of the Osd shader and kernel execution envirionments.
Changes:
- Merged far/patchBasis.cpp to osd/patchBasisCommon{,Types,Eval}.h
- Exposed PatchCoord, PatchArray, and PatchParam to Osd kernels
- exposed OsdEvaluatePatchBasis and OsdEvaluatePatchBasisNormalized
- Updated CPU, TBB, Omp, CUDA, OpenCL, GLSL, HLSL, and Metal evaluators
- Updated glFVarViewer
- identify the subrange of originating patch faces while assigning handles
- limit queries and memory allocation to the identified subrange of faces
- separate quadtree construction for quad and triangular patches
- added new PatchTable member to indicate uniform (linear) construction
- initialize new member in PatchTableFactory
- use new member to determine result of IsFeatureAdaptive() query
- added new TopologyRefiner member to detect presence of irregular faces
- added new Vtr::Level::VTag to indicate vertex incident an irregular face
- populated new VTag bit when irregular faces present
- updated refinement to clear new bit for refined faces
- branch adaptive refinement in linear cases to avoid testing features
- updated feature detection for irregular faces -- now a simple bit test
- updated PatchBuilder with now-trivial test for incident irregular faces
- individual basis functions now purely normalized with no PatchParam
- two new higher level functions deal with patch type and PatchParam
- updated Far::PatchTable and Osd evaluators that used old methods
- clarified handling of isolated/unisolated features in IsPatchRegular()
- simplified GetPatchBoundaryMask() to make use of bit masks
- removed private method supporting approx-smooth-corner-as-sharp option
- removed debugging tests verifying irregular patch points
- Far::PatchBuilder additions to identify spans around non-manifold corners
- re-organized patch regularity test to inspect individual corner features
- updated partial span gathering function to handle non-manifold cases
- ensure vertex tag xordinary bit remains unset when non-manifold
- added necessary options to struct LimitStencilTableFactory...::Options
- updated Create() to support creation of varying and face-varying stencils
- updated Create() to provide clarity and stricter compatibility checks for
the optional StencilTable and PatchTable arguments
- modified Doxygen comments for Create() to clarify requirements of the
optional table arguments
- added missing StencilTableFactory::AppendLocalPointStencilTableVarying()
- changed UpdateValues() use of *T to &T for consistency with PrimvarRefiner
- assigned unique types <T> and <U> to src and dst arguments for consistency
- kept the *T interfaces for backward compatibility
