- 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)
- 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...
Catmull-Clark Subdivision Surfaces", Niessner et al, Eurographics 2012.
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.
Make the sample locations dynamic by adding a velocity vector. Face boundary
crossing is handled using the new ptex adjacency functionality recently
added to the Far::TopologyRefiner.
- 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.
- remove obsolete glPushClient functions
note: this code is still duplicated in the ptexViewer (which still needs to be upgraded to the new framebuffer)
fixes#307
If the system has CLEW installed (which is detected by recently
added FindCLEW routines) then OpenSubduv would be compiled against
this library.
It makes binaries and libraries more portable across the systems,
so it's possible to run the same binary on systems with and without
OpenCL SDK installed.
The most annoying part of the change is updating examples to load
OpenCL libraries, but ideally code around controllers and interface
creation is to be de-duplicated anyway.
Based on the pull request #303 from Martijn Berger
