I have a set of meshes that I want to change as much as possible, while preserving their exact shape / silhouette. I want to know what tool to use. By change as much as possible, I mean ideally there would as few vertices as possible occupying the same place, and the polygon structure / graph structure would be different. I don't mind if it chanes the number of vertices or polygons, so long as their position and structure are different. Is there a tool I should be using to do this? The tools I've...

When I use it on my own meshes Meshlab crashes without any meaningful error message. My meshes are not more than 27K polygons (mostly quads in .obj format). I tried on a friend's installation and am having the same problem with these meshes. Because there's no error message I don't know what could be going wrong. Is there some kind of mesh pre-processing...
