There is this particular “Voronoi” effect I have been wanting to do for years. I have tried to achieve this particular effect using other 3D packages like Maya and Houdini.
Houdini is definitely the perfect contender for this. It is all procedural, so you can pipe in all kind of mesh and it will spit out different result each time.
And surely one can do the same thing using Maya and SOuP plugins, but it is a little bit more tricky.
We can now do it inside Blender with such ease and really fast. For a quick job.
I don’t know what to call it, but basically I want to have a “Cage” that is more or less based on Voronoi pattern. It is really simple actually. Just wireframe in 3D and with additional trickery to make it look interesting.
