Discrete Coons patches
Computer Aided Geometric Design, 16(7):671-689, 1999

Abstract: We investigate surfaces which interpolate given boundary curves. We show that the discrete bilinearly blended Coons patch can be defined as the solution of a linear system. With the goal of producing better shape than the Coons patch, this idea is generalized, resulting in a new method based on a blend of variational principles.
