Parametric surface is a surface defined by a tensor-product of parametric curves, which are represented by parametric equations. As such a surface comes with a well-defined mathematical definition, it becomes one of the most common geometric tools for computer-aided geometric design and for the object modeling aids of many computer graphics applications. Typical examples of such a surface include Bézier surfaces and non-uniform rational B-Spline (NURBS) surfaces. Unfortunately, because most existing graphics hardware only handle polygons, extra procedures must be carried out to convert a parametric surface into a polygon representation for rendering. This process introduces a significant bottleneck to graphics applications, which involve parametric surfaces, to assure interactiveness in terms of rendering performance.
