### Reduce a model to the exact number of vertices

For a research project we have to compare several meshes, unfortunately our method works best if the meshes have exactly the same number of vertices (faces are not important). Is there any way in Blender to reduce a model to an exact number of vertices? All I have seen so far is based on ratios, are inexact and usually involve faces not vertices.

I don't think that's possible. If it works, then it will only be by coincidence.

Meshes are usually reduced by collapsing edges, so one or more vertices might be removed

when a single edge is collapsed.

for a single object:

Code: Select all

`len(Ob.data.vertices)`

I'm sitting, waiting, wishing, building Blender in superstition...
