- changed template parameter to runtime method parameter
- added traits as static methods of all schemes
- constructed internal table of traits from all schemes
- move level of refinement / isolation into the Options structs
- fix splash damage in rest of the code
note 1: this is less than ideal, because most compilers accept the previous
call to these functions with an incorrect parameter list (ie. passing
the level instead of the struct issues no warnings and compiles...)
caveat emptor...
note 2: the level parameter names may not be final for adaptive modes
as we will likely want independent controls over crease vs.
extraordinary vertex isolation.
- 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.
- 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>
- 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.
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.

This change includes;
-topology identification for single-crease patch during adaptive refinement.
-patch array population (similar to boundary)
-sharpness buffer generation
-glsl shader
Eval stuffs will be coming.
- removed old alternative to Catmark feature adaptive selection
- removed unused methods from Vtr::SparseSelector
- made use of Level::VTag's new "incomplete" member in both
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.
