2551c32448 Fixed glsl shader portability 
- defined a fallback value for ROTATE
- made GetPatchLevel() a macro to avoid
  referencing gl_PrimitiveID from vertex shaders
- fixed float array initializers

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)

fixes #173

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.

c18cf5bff2 first pass at face-varying interpolation for CpuEvalLimit - still 
a couple of kinks to be worked out...

043369485c - adding varying data interpolation to the EvalLimit module 
- minor refactoring of the LimitEvalContext to accomodate all the data buffers

- pushing some minor sub-patch functionality back to FarPatchParams

- extend example code with randomly generated varying vertex colors

b270f99ea0 - prevent corner gutter texels from going into an infinite loop by 
adding an arbitrary break if vertex valence is > 256

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.

f2b3419a4d bug fix in limitEval example : calculation for the required number of samples was incorrect

f617cdd6ed Work in Progress : checkin in function kernels for boundary and corner patches. 
Casual testing doesn't reveal any bug within our sample shapes.

Remaining : gregory & gregory boundary patches.

393362b589 Cleaning up the feature adaptive patch colors : all example code now shares the same function to provide the patch colors 
Note : this function will probably eventually move down to osdutil or some similar canonical place

f25e89b745 Work-in-progress check-in for EvalLimit : 
- added boundary / corner kernel code

- bug fixes for Gregory patch kernel

- wired the new kernels in the controller class

Note 1 : corner / gregory kernels are not working yet

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

492238edd6 extending the "firstLevel" parameter to farMesh constructor.

87114f7428 Rename osd_util to osdutil. 
Cleanup the batching classes so that DrawCollection() no longer caches
current batch and effect. Any kind of binding optimization will be
handled in client's delegate class.
Also remove InitializeVertexBuffer method and add some arguments to
constructor instead.
