> If true, wouldn't be possible to join the two methods? For example I
might want to truncate all faces of dimension 1 in the cube with the same
coefficient. This would be a sort of intermediate between the two
currently available methods.
So I would say that the answer is No. The truncation method does things
simultaneously while face_truncation really needs the current whole
polytope in order to truncate a face with the appropriate proportion. This
operation does not commute with itself as even the second face may not be
a face of the result anymore. So I would leave the function as it
currently is...
I'm currently working on the conflict...
