Key words: Constrained surfaces
Springer Online Journal Archives 1860-2000
n -dimensional space, where n〉3. This definition can be used for given surfaces that are implicit or parametric. This paper presents a robust, adaptive polygonization algorithm for evaluating and visualizing geometrically constrained surfaces. Let be the constrained surface, a 2-surface in n-space, and let π( ) be its projection into the subspace spanned by the first three coordinates. Our polygonization algorithm computes π( ). The method works directly with the n-space representation, but performs all major computations in 3-space. Techniques for triangulation, polygon decimation, and local refinement are also presented.
