WebJul 11, 2007 · In this paper, I describe a simple 3D Voronoi diagram (and Delaunay tetrahedralization) algorithm, and I explain, by giving as many details and insights as possible, how to ensure that it outputs a correct structure, regardless of the spatial distribution of the points in the input. WebThe biggest problem I faced was finding a proper library for triangulating the points. I initially looked at libraries like Triangle[] and an open source C++ wrapper of Triangle[], but I had trouble getting both to compile.Eventually I ended up using another Delaunay Triangulation library from GitHub[].This library uses the Bowyer-Watson algorithm[], which is not a …
