This paper describes an algorithm for dividing a (u, v)-parametric surface into the least possible number of plane triangular elements that closely follow the surface they approximate. The concept, of closeness defined here is based on a set of three subdivision criteria: unit-normal criterion, chord-distance criterion, and edge-refinement criterion. The triangles generated by the subdivision, together with the unit normals at their vertices, serve as input to the ray-tracing program, which generates a shaded image of the surface with photographic realism. © 1990 Springer-Verlag.
