- 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...
- added an option to Far::StencilTablesFactory to generate stencils for
coarse control vertices
- refactored interpolation code out into Far::PatchTables
- corrected tangent interpolation
- code cleanup & comments
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.
The new table accomodates verts with valence up to 20.
Dr. DeRose provided me with a python script to generate the tables, but wants to
investigate a closed-form alternative to pre-computed tables.
Also: our logic is incorrect - it is missing adjacent face-points in the
interpolation (apparently this has been incorrect since day 1). Further fixes
coming next year...
fixes#246
The logic that invalidates the vertices in the control stencil and
the cached bspline patch weights was not triggering correctly.
Hopefully this new bit of logic should clear up some of the incorrect results.
fixes#246
Limit tangent stencil crease rule was accumulating the wrong vertices. This
change switches from using an Hbr operator to using a less efficient std::list,
but allows us to rotate around the vertex from an arbitrary starting incident
edge.
The values returned are "plausible", but more extensive testing would be required
to validate this new code.
fixes#246
The tangents were only scaled in the "bail-out" code branch that
pushes vertices to the limit and performs bi-linear interpolation.
Now we are also scaling the bi-cubic patch interpolation code branch.
There may be another code path left to fix (as well as some pointers
being currently unchecked)
fixes#243

- Adding FarStencilTables and FarStencilTablesFactory classes
- Adding Osd EvalStencil context & controllers for CPU, OMP and TBB backends
- Adding the code example glStencilViewer
- Adding reST documentation
- Changing version to 2.2.0_dev
- Fix HbrMesh::Unrefine function

Note 0: there is no stencil support for hierarchical edits
Note 1: there is no support for face-varying data stencils yet
Note 2: the current stencil factory is lazy but the caching system is not re-entrant
