Pixar will release the second version of OpenSubDiv at SIGGRAPH next week.
In the continuation of the OpenSubDiv initiative, version 2.0 of the open-source libraries for creating high-performance subdivision surface modeling tools will be released at SIGGRAPH 2013 in Anaheim.
The first version was released at last year's show in Los Angeles, and brought into action in January, just after SIGGRAPH Asia 2012.
The major feature will be the Evaluation API. This adds functionality to evaluate the SubDiv surface at an arbitrary parametric coordinate and return limit point/derivative/shading data. Project points onto the SubDiv limit and return parametric coordinates. Intersect rays with SubDiv limits. Pixar says they also expect further performance optimization in the GPU drawing code as the adaptive pathway matures.
