How do you chop up a tetrahedron into nicely-shaped little cubes? Here's one way, obtained a la symmetric moving frames (cs.cmu.edu/~kmcrane/Proje…). How else can you do it? pic.twitter.com/Cx3WyjYTJm

This is effectively a Catmull-Clark subdivision (with some 3D version) to get the parametric domain followed by smaller-cube refinement, btw.

Right. Here's a picture of the subdivision @amirvaxman_dgp is talking about, which can be used to trivially convert any tetrahedral mesh into a hexahedral mesh—but with poor angles near tet vertices. Any other way to split up a tet into cubes? :-) pic.twitter.com/W2aGRA691t

Nice ! But it is really a pity not to have access to some code to be able to reproduce yours results from Symmetric Moving Frames. Even Matlab code would be great. We are unable to benchmark with other methods.

Hi @angelo93728560, we’d love to get some example code out. In the meantime you can compare against our results (and many more) at hexalab.net @ALoopingIcon

I have to say that I love this discussion with 3D, drawings and topology 👌

It only works on things which are symmetric though?
