I’ve finally done it.  I’ve created dynamic boundaries on a grid system for a 3D Collada model in Papervision.  Yes.

Click the planes to make them active (walkable).  There is a tiny glitch that occurs when the character crosses onto a different grid piece along a corner, he jumps a bit.  I’m working on it.

*UPDATE* I just made a version with even more functionality. Now, you can only click planes that are adjacent to your character. When you walk onto a new plane, the surrounding “activatable” planes rise up, and down again when you leave the plane.
