The paper we intend to present deals with the problem of drawing parametric surfaces in real-time. A new fast sequential and parallel algorithm for approximate parametric surfaces with polygons is described. Its application on a single and multi-processor system is presented by emphasizing the constraints imposed by real-time applications for Virtual Reality. In particular a practical utilization of parametric surfaces for the modeling of a virtual hand-arm complex is described.
