International Conference on Curves and Surfaces, May 2000., Saint-Malo, France
This paper describes techniques for the piecewise linear approximation of trimmed NURBS surfaces. The problem, called surface triangulation, arises from any application in CAD and graphics. The new method generates triangular meshes that are adaptive to the local surface curvature. We use efficient data structures for the handling of trimming curves. We also generate Delaunay triangulation on the surface to improve the quality of the meshes.
