A short note on a Bernstein-Bezier basis for the pyramid

Published 23 Aug 2015 in math.NA | (1508.05609v1)

Abstract: We introduce a Bernstein-Bezier basis for the pyramid, whose restriction to the face reduces to the Bernstein-Bezier basis on the triangle or quadrilateral. The basis satisfies the standard positivity and partition of unity properties common to Bernstein polynomials, and spans the same space as non-polynomial pyramid bases in the literature.
