Class EdgeDetection
This utility analyses a mesh, finding a hash that indicates what it can connect two.
There's two steps to the analysis.
- For each corner of the cell, determine if it is inside or outside the mesh. This handles non watertight meshes.
- For each face of the cell, find the mesh edges coincident to that face.
The hashes are unique to a specific face and specific rotation of the tile, and are structured in a way that
you can get the same has for a left pointing and right pointing face if they share the same mesh edges and corners.
