(Processing) Primitives 3D

This is a simple example made with processings 3D api, in which some gray shperes rotate in the 3D space. To test the performance, I made it able to increase the number of shperes by clicking the movie. In my environment (2.4GHz core duo + 2GB memory), the movie starts to slow down after around ten shperes added to the stage. That is a bit slower than expected.
