@ -76,6 +76,16 @@ per-frame cost for adaptive drawing.
Similar to compute kernel simplification, this shader simplification has resulted
in additional simplifications in the Osd layer.
**Single Crease Patch**
OpenSubdiv 3.0 newly implements efficient evaluation of semi-smooth
creases(*) using single crease patches. With this optimization,
high-order edge sharpness tags can be handled very efficiently for both
computation time and memory consumption.

Catmull-Clark Subdivision Surfaces. Eurographics (Short Papers). 2012.
**New End-Cap Approximations**
While "legacy" Gregory patch support is still available, we have introduced

configuration (Gregory Basis end caps require one additional global shader
configuration).
The new implementations of GregoryBasis and BSpline endcaps relax the previous
max valence limit. Users are still encouraged to use models with vertices of
low valence for improved performance.
