Hi,

have anyone an example how to do a trace from a vertex. It is possible to detect level geometry?

Hi,

nobody have information about this? I can´t find an example and afraid that is it not possible with vertex shader.

I have tried to make a wave surfing on the beach shader on levelgeo but i looks terrible. So a terrain could make it better and i have experimented with a snow-terrain that aligns on levelgeo (Script for Snow/Sand-Terrain formed on level geo).

But for simulating waves rolling on the beach is to cpu expensive i think, not tried it yet.

So can a trace done with VS?

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.
