Geometric constructions for generalized barycentric coordinates
Spherical barycentric coordinates are introduced. Analogous to classical barycentric coordinates that describe the positions of points in a plane with respect to the vertices of a given planar polygon, spherical barycentric coordinates describe the positions of points on a sphere with respect to a given spherical polygon. They can be used to define 3D barycentric coordinates for arbitrary polyhedra.
