NURBS Tessellation with CUDA
Abstract:

NURBS, or Non Uniform Rational B Splines, are a curved surface representation commonly used in computer aided design and digital content creation. This recursive representation gives a great deal of flexibility, allowing arbitrary surface order and knot vectors, enabling a single NURBS surface to contain many contiguous patches. However, this recursive representation is also expensive to compute, so a NURBS surface is often converted into multiple Bezier patches before being tessellated. In this implementation, we present an efficient method for directly tessellating NURBS surfaces using the NVIDIA CUDA computing API.
