ok Rob. But what I'm workin on is a class to make object3D moves as particle. In my demo, those are plane, but it could be any other objects.
I'm currently gettin to my first goal (wrap gravity, boidin, flockin behaviour, etc...). but still need time to make it easy to use and "normalize" some parameters. My last problem deal with gettin a screenvertex from my object 3D, we've already talked about it, did you thought about it ???
