Abstract: Bézier surfaces offer powerful mechanisms to describe high quality models in computer graphics. In this paper we present a methodology for the implementation of the adaptive tessellation of Bézier models on the GPU. Tessellation is performed with variable resolution inside the patch to permit the use of meshes with a lower number of triangles but preserving a high visualization quality. Primitives are dynamically generated according to the results of local subdivision tests. The locality of the decisions assures that contiguous triangles are coherently subdivided.The resulting procedure is efficient, simple and generates the tessellation pattern of each Bézier surface dynamically. This enables tessellation of complex models to be performed in real time.
