Formula for point_to_mesh_distance metric

[lioutasb]

I'm new to the 3D representations literature and I was wondering if there is a paper or a specific formula that the point_to_mesh_distance function is based on. The documentation is lacking details as to what distance is used or how a specific "type" of distance that calculates is selected.

Same. The distance value is quite wired in the example.

It seems the result of point_to_mesh_distance is actually the squared unsigned distance.
So you have to use the square root of the output as the real unsigned distance.
