Schnyder Tree 100k

sketchfab

This is a uniform random sample of simple triangulations with 100,000 faces whose edges are oriented to ensure each vertex has an outdegree of exactly three, except for the three vertices connected to a distinguished face, which have an outdegree of just one. The edges are colored so that at every vertex, all incoming edges of a specific color fall between the two outgoing edges of the other two colors. Only the edges of a single color can be seen on this model.
