Abstract: Bézier surfaces are widely used in computer graphics applications. Rendering of such surfaces is commonly performed by tessellation. In order to generate less triangles for high quality surfaces, adaptive tessellation algorithms are better. The geometric tests used by these algorithms per- form vector computations of high latency that decreases the performance of the algorithm. We propose an adaptive tessellation algorithm that avoids vector computations for tests, replacing them with scalar computations. This way, latency of tests is reduced and therefore, performance improved.
