Quote: But for simulating waves rolling on the beach is to cpu expensive i think, not tried it yet.
I could imagine that this were possible with vec_for_vertex/vec_to_vertex when you take a quite small terrain which moves around with the camera, while its skin moves relating the ground. I saw a wave riding game on Nintendo 64 that seemed to work this way. In that game the properties of the waves changed related the place that you were passing.
Hope, this gives an idea how to achieve the effect that you need.
