Most of the previous multiresolution models use exclusively the triangle graphic primitive both in the data structure and in the rendering stage. Only a few models use another graphic primitive in this rendering process and just one uses the triangle fan as the basic primitive of the model. In this paper we present the first multiresolution model, Multiresolution Triangle Strips, that uses the triangle strip in the data structure and in the rendering stage. Each triangle strip is represented as a graph and all levels-of-detail of this strip are stored in it. The extraction algorithm traverses the graph to obtain the triangle strip at the demanded resolution. The use of this primitive speeds up the rendering process as the number of vertices sent to the graphic system is reduced. KEYWORDS.
