Mesh expansion and comparison

[mouawadma]

Hello, I know this project is not being maintained but was hoping to get some help.

I am very new to meshes and working with them so this question may be naive. Essentially I have 2 meshes, a base mesh and a resultant mesh. The resultant mesh is made through operations on the base mesh. To keep it simple, let's say that the resultant mesh is the base mesh + an expansion,(not just scaling but a dilation) of some distance. I essentially want to take the base mesh, recreate the resultant mesh (do the known operation) and then compare the two meshes to see if they are relatively "the same" (which I know could mean lots of different things but maybe some sort of overall distance metric between the two?).

Any advice would be appreciated and any book resources would be helpful

Thanks
