I've been doing a lot with point clouds over the past 1.5 years, mainly to create microbot assets for the Intopolis game. 3D scanning, fractal generation, timeforms, and other procedural techniques are all being employed to generate assets. I have commissioned custom Python code and Rhino scripts to generate volumetric ones because there was no current way to do it with the existing tools (barring maybe Houdini).
I have been a bit obsessed...
