Thank you so much for your help, it was very helpful.

you'll only get org data, before any modifier is applied… Since cloth's
pointcache data do not seem to be available from Python, the only thing
you can do to get cloth cos of vertices is to applies all modifiers,
like this e.g.:

applied.
> tmp_me = obj.to_mesh(_scene_, True, '_RENDER___')
> 
> # Use
data from tmp_me...

>
bpy.data.meshes.remove(tmp_me)
