Weight Interface Reference

Dmitry Anisimov

Many geometric algorithms rely on weighted constructions. This package provides a simple and unified interface to different types of weights. In particular, it includes numerous weights with a simple analytic expression, generalized barycentric weights, and weighting regions. All weights are available both in 2D and 3D.
