Optimizing tetrahedralization smoothness #39

Open ttsesm opened 2 years ago

ttsesm commented 2 years ago

Hi guys,

I am trying to achieve a 3d mesh cell fracturing to smaller pieces something similar to this blender addon https://www.youtube.com/watch?v=ZG_ZMnKzVTQ

I've managed to have something running already as you can see from the images below: image image

However, as you can see the fragmented parts look too rough due to the internal tetrahedralization. Thus, my question is whether it is possible to obtain smoother cuts like the ones exemplified in the video. I've tried to play a bit with some parameters as 'mindihedral, 'minratio,maxvolum`, etc... but I still the result is not what I would like.

Any idea how I could improve the tetrahedralization smoothness?

Thanks.
