cf13a8d755 Add check in shape_utils that detects dicsonnected vertices in a shape mesh and exits with an error message. 
A more permanent fix will be to handle fully non-manifold topology at the Hbr level, but that is beyond the
scope of fixing this problem.

fixes #175

54bef92aab switch cpuEvalLimitController to use a quad-tree based patch access map : 
- remove PatchMap from FarPatchTables

- add a new FarPatchMap quad-tree class (constructed from FarPatchTables)

- refactor the EvalLimitController to use the quad-tree search instead of a
  serial loop access

7cb2463dc7 fix FarPatchTables::IsFeatureAdaptive() : 
- trivial return if Gregory specific patch data is set
- or iterate through the patch-arrays until an adaptive patch is found (REGULAR,...,GREGORY_BOUNDARY)

419b6b9716 - add a message to limitEval when trying to display face-varying UVs on shapes 
that do not have that type of data

- fix some regression shapes that had "empty" uv values
  (including some minor topo surgery that luckily appears to not break
  regression baselines)

cf1b2f1334 - fix a face-varying bug in shape_utils : now face-varying UVs are indexed correctly 
coming out of our shape format

- set blue component of point-cloud to 0 in face-varying mode (save a few micro-secs)

307b353b13 shape_utils : make sure we don't create a mesh with face-varying data declared 
if the shape does not actually contain usable face-varying data.
 2013-06-07 10:40:11 -07:00

f5a7ad4cdb evalLimit example : make sure to reset the output buffer on creation - some of the prims may not 
set all the point colors (if face-varying data is missing on the test shape for instance)
and we don't want random values creeping from unset memory allocations.

043369485c - adding varying data interpolation to the EvalLimit module

21b9fbbb95 Moving some member variables of OsdGlDrawContext from public to protected 
and adding the requisite accessors

Note : all our example code goes through the same boiler-plate texture
binding code - we might want to move it as a member function of the DrawContext.

- added boundary / corner kernel code

Note 2 : the vertex mirroring solution used for boundary / corner kernels could be incorrect...
