- updated usage of revised Vtr gather methods in Far
- fixed warnings redeclaring names of local variables already in use
- 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
- change topology refiner to check for edge sharpnesses when selecting faces for isolation
- add face-aggregator for edge tags to Vtr::Level
- fix logic in Far::PatchTablesFactory to correctly tag single-crease patches along infinitely sharp edges
note : this fix is a bit of a cludge - barfowl confirms that the vertex crease tags (VTags) are intended to
carry neighborhood information, which they currently do not. we will revisit this shortly and fix the tags,
which will allow us to simplify the traversal logic when isolating topology features.
fixes#369
Const' declared instances of Vtr::Array do not protect the pointer held
privately by the class properly. In order to force the compiler to
protect this pointer, we removed all non-const accessors from Vtr::Array
(now renamed Vtr::ConstArray) and moved them to a child class (Vtr::Array),
which requires const_cast<> operators internally to allow access.
The change & renaming is then propagated to all internal dependencies.
- VVarBoundaryInterpolation is now VtxBoundaryInterpolation
- enum prefix change from VVAR to VTX
- generel cleanup / doxyfication
- update of beta / release notes
- add error reporting callback to Vtr::Level::validateTopology
- switch printfs to callback
- add error code enums to Vtr::Level
- route Far::TopologyRefinerFactory::reportInvalidTopology through Vtr::Level callback
note:
- Vtr::Level::validateTopology needs to check creaase tag indices
- topology validation should be client-code driver in TopologyRefinerFactory (turned off in the code at the moment)
- added flag to Sdc MASK interface to interpret "face weights"
- updated Catmark and Bilinear schemes to be aware of new MASK flag
- added subdivision and limit masks for the Loop scheme
- subclassed Vtr::Refinement into QuadRefinement and TriRefinement
- updated tagging of components to be sensitive to applied scheme
- fixed some quad assumptions in FVar refinement to support N-sided
- internally generalized ::TopologyRefiner Interpolate() for <SCHEME>
- 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
- 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
- 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.

Sync'ing the 'dev' branch with the 'feature_3.0dev' branch at commit 68c6d11fc36761ae1a5e6cdc3457be16f2e9704a
The branch 'feature_3.0dev' is now locked and preserved for historical purposes.
