get the result of a clip ? (road on terrain follow-up)

I am still on my road on dynamic terrain problem and the more I think about it, the more I think the perfect solution would be to get the result from a clipping operation.

for example, I have a terrain( i.e a triangle list), I clip it with 4 (vertical) plane and get another triangle list. The original is not modified and I can use the clipped copy as the geometry for my road.

I see more applications

But I don’t know if it is possible natively with Panda…

Any idea ?

Nope, sorry. At least not automatically. You can always write your own clipping algorithm.

The effect you see from Panda’s clipping planes is implemented by the graphics hardware, not by Panda itself, so it’s not possible to get the results in your application.
