Well it sounds expensive but perhaps you could use something like I did. My dynamic Object "scans" it´s near environment. It does this with the help of a function like "DeliverAllPolygonsNearMyPosition". Then I create a little trimesh out of this Triangles and do the ode collision detection only with this trimesh. At the moment I am doing this for every frame and the performance is ok. I´m doing this due to the lack of memory (the whole geometrie is also stored in another tree and I don´t want to hold it twice). Any other suggestions would be appreciated.
