Is there a way in Blender to compare two pieces of mesh or two meshes to its similarity? Maybe with some script or an addon.
What I mean: there is a stone or brick broken into half for example:
This is a kind of forensic or architectural task. The goal is to prove that those 2 pieces have similar surfaces and may be connected to each other with some threshold or they were a one piece before. I know of "select similar" in Blender, similar face area in this case, but it doesn't work quite well for such a task.
I am not a coder so I can't figure out a possibility of solving this.
So what is the way to do it?
