- extend Far::PatchTables data structures & interfaces to store requisite
information for channels of face-varying bi-cubic patches
- implement gather function in Far::PatchTablesFactory to populate face-varying
channels with adaptive patches
- extend accessor interface in Vtr::Level
- propagate code fall-out throughout OpenSubdiv code base, examples & tutorials
- extend vtrViewer code to visualize tessellated bi-cubic face-varying patches
- added new tag for sharp corner, now used in isolation
- split single semi-sharp tag in two for vertex and edge sharpness
- updated tag propagation and all tests of previous semi-sharp tag
- added clear() methods for all tags and simplified initialization
- added Vtr::FVarLevel method to resolve correct index in level 0 case
- updated tag retrieval methods that used face-value array as input
- changed signatures to accept face-verts when needed and updated usage
- added methods to FVarLevel to combine FVar tags with vertex tags
- use composite of combined tag to find FVar features needing isolation
- added more tagging related to the "linear borders" interpolation case
- added FVar channel consideration to TopologyRefiner's feature selection
- added more simple access methods to FVarLevel
- added _xordinary tag to FVarLevel::ValueTag; initialize and refine
- added composite tag method for FVarLevel::ValueTag similar to Level::VTag
- parameterize FVar topology initialization with regular valence
- recent MSVC versions attempt to compile files with hlsl
extensions when passed on the command-line. This breaks
the build because these files are not meant to be compiled
directly by MSVC. I removed the dependency from the
CMakeList to prevent this from happening.
- move patch interpolation code out of Far::PatchTables into far/interpolate
- add bilinear quad interpolation function with derivatives
- switch OsdCpuEvalLimitController to far/interpolate
- add support for bilinear quad interpolation & clean varying interpolation
- add simple parsing function to the Shape class
- only a small portion of the MTL format is supported (no textures)
- the feature is disabled by default
- this work is incomplete : we still need to add piping to the GPU
