Added support for gathering face-varying patch points to
the Far::EndCap*PatchFactory classes. Also, changed these classes
to compute varying stencils optionally, since separate varying
stencils are not needed for face-varying patches.
Also, removed a no longer used stateless factory method from
the EndCapGregoryBasisPatchFactory.
Re-organized the implementation of the patch table factory
in advance of adding support for bicubic face-varying patches.
- Renamed the AdaptiveContext internal class to BuilderContext
since this can be used (eventually) to build patch tables for
uniformly refined topology as well as adaptively refined
topology.
- Added utility methods to gather patch vertices from the
levels (and eventually fvarLevels) of a refiner.
- Replaced the FVarChannelCursor with a simpler array of integer
face-varying channel indices.
- Extracted the topology inspection needed to identify
patches into a computePatchTag() method.
- Simplified the two-pass traversal of the topology into a
single pass traversal of the refined topology followed by
an iteration over the patches that have been identified.
- Replaced internal templated PatchTypes class with simpler
and more direct accounting and patch array building facilities.
- Changed the API of the end cap patch factories to no longer
depend on the patch table factory's PatchFaceTag. This has
been superseded by the specification of appropriate
VSpans at the corners of the end patch.
- added definition and gathering method to Vtr::Level
- extended Far::EndCap...PatchFactories with VSpan[4] for patch corners
- extended Far::EndCapGregoryPatchFactory to avoid last level assumption
- adapted Far::PatchTableFactory to use above extensions
- extended Far::GregoryBasis to recognize VSpan corners
- simplified Far::GregoryBasis treatement of boundaries
- fixed bug in Far::GregoryBasis related to smooth corners
- instead of accumulating GregoryBasis::Point (fixed size stencils
backed by stackbuffer), pack the stencils into StencilTable as they
are evaluated
- use single integer for varying stencils of patch points, not
a GregoryBasis::Point
- cap the reserved stencil entry size.
- replace std::vector with vtr::StackBuffer in GregoryBasis::Point
- remote getQuadOffsets call from ProtoBasis
- rewrite some inefficient code in the endcap generation.
Note that this is a temporary remedy for the performance issue in 3.0.
We'll fix it again in the later release.
- eliminated need for disabling warning 177 in far/patchTableFactory.cpp
- encapsulated all floating point equality tests (1572) in local functions
- bracketed all ICC specific warning pragmas with #ifdef __INTEL_COMPILER
- avoided GCC's stricter shadowing warning in vtr/array.h
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.
- 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.
