Reference Manual

Dmitry Anisimov, David Bommes, Kai Hormann, and Pierre Alliez

This package offers an efficient and robust implementation of 2D generalized barycentric coordinates defined for simple polygons in the plane. If coordinates with respect to multivariate scattered points instead of a polygon are required, please refer to natural neighbor coordinates from the Package 2D and Surface Function Interpolation.
