Tessellation in OpenGL has some limitations that can be overcome by writing your own tessellation in CUDA--allowing for higher-order surfaces, custom UV coordinate determination, and advanced features such as trimming curves. This part of the session will cover how to set up tessellation of simple cubic Bezier patches in CUDA, including how to generate UV coordinates and compute tessellated vertices and triangles in parallel. It will also explore advanced tessellation using other basis functions, higher-order curves, and trimming curves.
