From a triangulation of a sphere to a 4-regular planar graph in the minimum number of topological changes?

Given a triangulation of a sphere (coming from the convex hull of some points on that sphere), I need to get to a graph with these points as the vertices, where each vertex is connected by edges to ...

Computing accurate mesh normals

Suppose we have a mesh $M$ with a vertex set $V$, a facet set $F$, and an edge set $E$. For simplicity we may assume all facets are triangular. $M$ is viewed as an approximation of a parametric ...
