of this quad to be tagged as boundary. These vertices will cause the
feature adaptive pass to generate sub-faces where appropriate, however
the face itself will not be identified as "non-patch", which causes the
FarPatchTables factory to mis-identify it and fall-back on an assert.
This fix flags these particular quad faces in the first adaptive pass.
The particular shape that caused the crash has also been addded to our
regression suite.
fixes#159
- [Feature Adaptive GPU Rendering of Catmull-Clark Surfaces](http://research.microsoft.com/en-us/um/people/cloop/tog2012.pdf).
- New API architecture : we are planning to lock on to this new framework as the basis for backward compatibility, which we will enforce from Release 1.0 onward. Subsequent releases of OpenSubdiv should not break client code.
- DirectX 11 support
- and much more...
- generate baseline data with the new hbr_baseline tool
- run the a regression of the current hbr code over the baseline data-set with hbr_regression
There is still some cleanup to do to generalize some of the "shape" code as our intermediate
obj-like file format is unfortunately entrenching itself (we should really be using RIB...)
There is also a fair amounto f copy/pasted stuff in the regression code that needs to be refactored
Closes#32
