Schnyder Tree 100k

sketchfab

This is a triangulation taken uniformly at random among simple triangulations with 100 000 faces whose edges are oriented in such a way that each vertex has outdegree equal to 3 (except the three vertices incident to a distinguished face, which have outdegree 1). The edges are colored in such a way that, at each vertex, all incoming edges of a given color are inbetween the two outgoing edges of the other 2 colors. Only the edges of one color are visible on this model.
