Quote - This is great stuff. I'm sure I will be using some of those scripts. Certainly there is a whole array of methods and processes being tried out, and that in itself is fascinating to watch, even though some of the maths in beyond me.
I was very interested in reading about your experiments with using UV's to compare meshes. It looks like that method doesn't help to solve the overall problem of comparing two meshes, but I am very grateful to you for spending your time trying it out and displaying the result.
Hi, Ian! Thank you for the comments. :D The math really isn't that difficult most of the time, because I don't understand the really difficult math well enough to use it effectively. :lol: Vector math is actually fairly simple, once you grasp the difference between a directional vector and a coordinate vector. It particularly helps to be able to visualize what the math is doing, as you go along. Which is where PoserPython is useful. You can write a script and, assuming it doesn't crash on you (:lol:), you can see what it does right away.
Now, matrix algebra and quaternion math and anything which delves intensively into angles, there I get lost very quickly. :lol: And I can still only read summation notation every now and then. (Why don't they explain what all the variables represent? There must be a universal standard set of symbols in use, and I don't have the key to read the code....)
Sadly, something about the process of indexing back and forth between vertices and texvertices also seems to confuse me quickly. I've reached the point where I'm (hopefully) fairly adept at it when handling one mesh, but when trying to do this indexing while working with two meshes simultaneously, I still get lost.
:lol:
But both of the UV processes tested above show some promise and I'm sure I'll come back to them. I think Spanki's correct and comparing two geometries through their matched UV's presents more complications than I initially grasped, and possibly more than I currently grasp. One of my problems is that I only have one example on which to test the idea, which is the Antonia-Lo to V3 set, and the Antonia-V3 remap isn't available to the general public yet. (I was sure dphoadley had many free remaps out there, but I can't find them....)
So I may come back to the idea later. It's an interesting experiment. :laugh: Again, my apologies for having misunderstood what you were suggesting, initially. I jump to conclusions, you see.... :blushing:

Cage can be an opinionated jerk who posts without thinking. He apologizes for this. He's honestly not trying to be a turkeyhead.
Cage had some freebies, compatible with Poser 11 and below. His Python scripts were saved at archive.org, along with the rest of the Morphography site, where they were hosted.
