The kinetic chromeball animation project was my last project from my Procedural animation class.
First i did the structure. The back wheel is procedurally made, then the rails were made using lines and circles to create a 3D rail. The animation was done usign a rigid body simulation for just one ball to make it go down the path, then i copied that animation a few times to have more balls rolling (something professor Deborah Fowler suggested).

The shaders for the balls and the rails were made procedurally as well using a piece of OSL code that i did in other class.
