- reorganized Refinement methods and pruned excessive comments
- removed and added assertions related to Catmark scheme
- added code to support alternate refined vertex ordering
- updated FVarRefinement to be more independent of vertex ordering
- updated Far::TopologyRefiner to fix face-varying ordering dependencies
- fixed a few miscellanous compiler warnings
- adding support for StencilTables creation from a Gregory basis
- fix a bug in the prot-stencil allocator (slow memory pool was not being cleared properly)
- added array accessors to properties of vertex values in vtr::FVarLevel
- updated construction of base level face-varying topology
- simplified population of face-varying properties in vtr::FVarRefinement
- updated Far::TopologyRefiner::Interpolate/LimitFaceVarying() accordingly
Setting start/end values of UpdateValues() produced incorrect primvar interpolation
because the stencil sizes array was not shifted properly to the 'start' location of
the batch.
- added ValueTag indicating sharpness dependency on another value
- updated base level tagging to identify dependent semi-sharp values
- updated refinement to consider dependency when reassessing semi-sharpness
- updated interpolation to use dependent fractional weight when necessary
- adaptive mode: remove faces tagged as holes from the selection of faces to isolate
- uniform mode: faces tagged as holes are still included in the refinement process,
however they are removed from patch tables
- future improvements: add a 'selective refinement' code path separate from 'uniform refinement'
to handle this case without un-necessary subdivision work.
- re-implement the pool allocator
- use templates to remove code redundancy between regular & limit stencils
- leverage [] operator overloading to simplify stencil factorization
- add the ability to treat subdivision levels independently (see below)
- refactor Far::TopologyRefiner::Interpolate<>() methods to pass buffers by reference
(allows overloading of [] operator)
- rename some of the stencil factory options
- propagate changes to Osd / examples / tutorials...
- remove #version declaration from the kernel code
- move it in front of shader sources before compiling to prevent some drivers from throwing errors
fixes#360
Cause: std::vector.resize() function invalidates Vtr::Level pointers held by FVarLevel
Fix: switch std::vector<Vtr::Level> to std::vector<Vtr::Level *> and cycle through
the vector with appropriate new/delete.
