We propose a novel approach to the problem of polynomial approximation of\nrational B 'ezier triangular patches with prescribed boundary control points.\nThe method is very efficient thanks to using recursive properties of the\nbivariate dual Bernstein polynomials and applying a smart algorithm for\nevaluating a collection of two-dimensional integrals. Some illustrative\nexamples are given.\n
