- added new public member to PatchTableFactory::Options
- replaced internal option with new public option
- updated tagging and Gregory conversion for sharp patches
- changes mainly involve Far::PatchTableFactory
- treatment of patches more clearly separated into regular and irregular
- patch identification now determines regularity and defers classification
- topology inspection specialized for regular vs irregular patches
- face-verying patches re-use patch information when topology matches
- added Vtr::Level methods to improve access to tags for face-varying values
- improved initial tagging of face-varying values in Vtr::FVarLevel
Updated Far::PatchTableFactory to be able to populate patches
for smooth evaluation of face-varying data channels.
- Moved computePatchTag() method to BuilderContext
- Added computeFVarPatchTag() method to BuilderContext
- Use Vtr::Level::VSpan to represent the partial ring
around vertices for face-varying patches.
- Added the option generateFVarLinearPatches (defaults
to true) to support the legacy behavior of generating
linear patches for face-varying data channels regardless
of the underlying face-varying linear interpolation modes.
In order to support a consistent API for refinement and
evaluation of varying primvar data, Far::PatchTable needs
to provide indices for varying data. This adds support to
Far::PatchTableFactory for generating these indices.
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been superseded by the specification of appropriate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.
There's a lot of good foundational work here to eventually support
smooth interpolation of face-varying patches. Unfortunately, this
is not quite ready to release. Therefore, we've decided to defer this
feature until a later release.
This change hides this code behind the FAR_FVAR_SMOOTH_PATCH macro.
