0232ff5543 Fixes limit stencil evaluation on gregory basis patch. 2015-04-10 17:45:00 -07:00

8da827336d Removes FarKernelBatch.
This is the first step to tease off Osd compute controller/contexts
from Far API.
Currently FarStencilTable only creates a kernelbatch for the entire range,
so we can use [0, numStencils) for all cases instead of KernelBatch.
This might not be true if we apply non-factorized level-wise stencils,
then we'll add another modular utility to serve those cases.

24f9dc154b Enable GregoryBasis patch.
PatchTablesFactory fills 20 indices topology into patchtable, and use it for eval and draw.

note: currently screen-space adaptive tessellation of gregory basis patches is
broken and cracks appear around them.

d0a624f373 Add "smooth UVs" to Far
- 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

- renamed Sdc::Type to SchemeType and TypeTraits to SchemeTypeTraits
    - renamed TYPE_ prefix to SCHEME_
    - updated all usage within core library
    - updated all usage in examples, tutorials, etc.

c2e8148efc Fix a Far::StencilTablesFactory crash bug on 'perfect' topology
Torii (and other planar topologies) are made entirely of regular b-spline patches and do not
generate sub-patches through adaptive isolation: we need to make sure that we construct
stencil tables with singular stencils for the coarse vertices instead of returning empty
tables (and crash in the limit stencils factory)

abae4459e6 Adding support for gregory patches limit interpolation to Far::PatchTables
note: limit interpolation requires stencil-driven Gregory basis CVs

cc2e338ef6 Refactor Far::StencilTables and factories
- minor code cleanup (style consistency)
- move proto-stencil code out of the stencil factory
  in anticipation of Gregory stencils implementation

f145f70fd2 Refactor Far::StencilTablesFactory
- 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...

d02bfc48d2 WIP on LimitStencilTablesFactory
- 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

4dd366593d WIP FarLimitStencilsFactory
- bi-cubic patches should be mostly covered, although portions of the interpolation code
  need to be refactored out into Far::PatchTables as vertex templated functions (following
  patterns established in the Far::TopologyRefiner)

- end-cap patches still have to be done (prob. going to drop Gregory in favor of bilinear)

- Presto needs a fully bilinear code path (no patches) - really ???

c399655dcc Landing 3.0.0.alpha
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.
