Cell Growth 3D

Following previous experiment in Cell Growth 2D using processing, I try to extend it to 3D using Python in Maya.

In this case that I want to program the agents to first construct the internal structure . Then at a point when the equilibrium breaks, It will start to fill the outer skin. So far, it looks good with simple geometries

Following are a few renderings in the process that looks nice. Not necessarily have anything to do with the logic itself.
