Abstract
Parametric curves and surfaces have been defined for a long time in mathematics, and used extensively in engineering and more recently in computer aided design. In computer graphics outside of CAD, they have been used from simple object models with a few patches to 3-D animation models with several hundred patches.
In spite of all this activity, they still look a little forbidding to most people in computer graphics. This paper attempts to address this problem by describing the motivations, properties and references for the most common types of parametric curves and surfaces.
