Symmetric recursive algorithms for surfaces: B-patches and the de Boor algorithm for polynomials over triangles
Using the polar form of the bivariate polynomials F the author constructs a new representation for F and calls it ``B-patch representation''. The B-patches are a generalization of the known Bézier patches and reduce to them for particular choice of the knots. A de Boor-like evaluation algorithm is discribed for the B-patches and their most important properties are discussed.
