using muMatch to find correspondence points in different type of mesh models #2

Open ttsesm opened 2 years ago

Hi,

I would like to ask whether the muMatch approach could be used to find correspondence points between two meshes that snap together and not overlapping. For example I have the following two meshes: image Now I would like to find the correspondent matched points on the sides that the two meshes snap together. Would that be possible?

I've tried to adjust the code to run it on my sample meshes and see what the output is but then I've encountered the following issue:

Thanks.

@jjk01 any hints for the issue above?

Hello, sorry for the very late reply to this. I'm afraid that this algorithm is not able to solve your problem (it is for finding a match between two similar meshes rather than being able to align two halves of the same mesh).
