COONS TRIANGULAR BÉZIER SURFACES

Abstract

In this paper we give some different surface generation methods starting out from prescribed boundary curves. If the boundary control points are known it is natural to think of Coons patches, a popular solution of the problem of finding a surface given its boundary curves. We have developed three methods to generate triangular patches given the boundary curves. First we give a discrete version of the triangular Coons patch. A second method lets us to find the extremals of a functional as a solution of a linear system of the control points. That functional is the one that minimizes the Coons patch. The third method makes it possible to build a Bézier triangle by means of a mask deduced from the characterization of cubical extremals of the functional.
