Identify plane of symmetry in 3D mesh Is there an efficient way to identify the plane of symmetry in a 3D mesh? Preferably with existing code / software but if anyone knows how to implement it that would also be helpful.

Example of the problem: you have a 3D mesh of a duck that is centered at the origin. The correct answer in this case would be the plane where x = 0.

There are definitely other papers on the subject though
