Below there are two identical meshes, however the first one has edges moving in random directions, the second one has edges moving in a orderly, uniform fashion (edge flow).

enter image description here

i want to be able to make a mesh with uniform edges (good edge flow) from a mesh with bad edge flow.

    $\begingroup$ I think you need to provide some more background to your question. $\endgroup$ – Simon F Jun 20 '17 at 9:20
  • $\begingroup$ Please narrow down the question with more detail on what you are looking to achieve. It might also help to describe what information you already have about the mesh, perhaps with an example. $\endgroup$ – trichoplax Jun 20 '17 at 11:42

    $\begingroup$ Sorry to be a pain, but what defines "good topology" vs "bad topology"? Are you after the effectiveness of each polygon, or how regular the mesh is? $\endgroup$ – Simon F Jun 21 '17 at 9:09
  • $\begingroup$ good topology is a low polygon mesh with faces in the right location such that when animated the mesh deforms properly. i want to generate a low poly mesh FROM the high poly mesh with good topology $\endgroup$ – Mark Markrowave Charlton Jun 21 '17 at 20:12

    $\begingroup$ Sounds like you want to perform curvature-aligned remeshing, see e.g. hal.inria.fr/inria-00099624, users.cs.cf.ac.uk/Yukun.Lai/papers/remesh_cad.pdf $\endgroup$ – Rahul Jun 24 '17 at 6:20
