CG Modeling 2: NURBS

NURBS geometry is used to create mathematically accurate curved surfaces, such as those in automobiles and airplanes. In film, the advantage of NURBS surfaces is that they render well and are more easily controlled for animation than dense polygonal meshes. In video games, NURBS are rarely used, but when they are, it is as intermediate objects made during the polygonal modeling process or as high resolution geometry rendered for cinematic sequences.
