Algebraic Geometry Foundations numbers such that . everywhere on R? How may we generalize to polypols? Can we find basis functions for higher-degree approximation by similar techniques? Is there some unifying theory that will facilitate extension to higher-dimensional elements?

Rational Wedge Construction for Polycons and Polypolsthe properties enumerated in Sect. 1.5 are achieved. We first elaborate on the construction mentioned in Sect.3.1 and then prove that this construction yields the required properties. Polynomial P. in the numerator is called the .. It is the product of the linear and quadratic forms which vanish on

Two-Level Computationlgebraic geometry concepts were invaluable in the analysis. It was demonstrated that by appropriate choice of nodes any prescribed degree basis can be constructed for any well-set algebraic element. Practical guidelines were presented for numerical quadrature over elements. The analysis is of intere

Higher DimensionsChap. 7 of Part I. The GADJ algorithm generalizes to polyhedra. If a polyhedron is bounded by n planes, a unique surface of maximal order n − 4 on which the denominator vanishes may be computed from the divisor group (excluding the vertices) of the boundary planes. The denominator is found easily by

Forty Years Afterarren. These nonrational alternatives include kernels based on contour integrals for elements with curved sides. Much effort has been directed toward areal coordinates which are degree-one interpolation functions adequate for graphics application. Higher degree interpolants apply to patchwork polyno
