How is it possible to do that?

(I'm not denying that games do it - they obviously do - I'm curios as to 
how it's possible to do this given that the GPU only knows about 
polygons and texture mapping.)

...which is more or less what I'm trying to use RK4 for! :-}

(I imagine a game physics engine uses something a tad more sophisticated 
than just moddling a few points and allowing arbitrary interactions though.)
