Abstract:
OpenSubdiv [Pixar 2012] is the de-facto industry standard for the representation of subdivision surfaces. Its feature-adaptive subdivision [Nießner 2013] allows for efficient display using rasterization hardware. Based on this feature-adaptive refinement of creases, semi-sharp edges, and irregular patches, we introduce an efficient algorithm for ray tracing the resulting patches up to almost floating point precision.
