This is what i (try) to do with terrain - box collision. I "project" the AABB 
of the colliding box onto the terrain, extract all the triangles from the 
"projected" area. Since my vertexspacing isn't that small i always get 1-8 
triangles and i think that's acceptable (well, actually it doesn't work 
yet...)
