2D Generalized Barycentric Coordinates Reference

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

The package 2D Generalized Barycentric Coordinates offers an efficient and robust implementation of two-dimensional closed-form generalized barycentric coordinates defined for simple two-dimensional polygons. 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.
