NURBS(Non Uniform Rational B-Splines) are nearly ubiquitous for computer-aided design (CAD), manufacturing (CAM), and 3D modelers and part of numerous industry wide 3D data exchange standards such as IGES and STEP. With a rapidly growing hardware system, NURBS is getting more attentions in real-time systems or 3D games. In this new trend, the biggest obstacle is that tessellating NURBS into triangles is still slower than loading pre-triangulated data.
