    $\begingroup$ Out of curiosity, how did you manually distribute the points? $\endgroup$ Commented Mar 22, 2022 at 15:44

    $\begingroup$ (1) Once you have a mesh, you can stretch the mesh coordinates. (2) Is the stretching to preserve the volume/area of the cells? (Is there a physical model, or are you after a geometric effect that need not be physically accurate?) $\endgroup$ Commented Mar 22, 2022 at 17:13
  • $\begingroup$ @user21 initially, Lloyd's relaxation. the stretch was done by a parametrized rescaling $\endgroup$ Commented Mar 22, 2022 at 23:37
  • $\begingroup$ @MichaelE2 there are plenty, mostly energy-based. Look at Farhadifar's vertex model, for example. But I'm looking for something simpler to avoid any kind of cell intercalations (or T1 transitions). So simply readjusting the vertex positions with some force transmission that preserves cell shape to some degree. $\endgroup$ Commented Mar 22, 2022 at 23:39
  • $\begingroup$ One alternative to vertex models could be to consider a spring-based model, where each pair of vertices is connected by a spring with an associated stiffness, but I'm not too sure how to implement that, and whether stretch forces are easily transmissible on that system. Any suggestions are appreciated $\endgroup$ Commented Mar 22, 2022 at 23:47
