I have a dynamic surface in WebGL, that is animated in vertex shader. I want other objects to interact with this surface (for example, an object riding on dynamic terrain). What's the best way to do this? Should all these calculations be done on CPU? Is there a way to calculate this stuff on GPU?

Basically, what I want is vertex shader with access to other (already transformed) vertices -- that would be perfect.
