Hello!
I know how to collide objects against a terrain heightfield, or a uniform triangle grid.
But how would I go about implementing collision detection with a terrain as an arbitrary triangle mesh?
For example with a height field you can't have tunnels or any kind of 'depth' to your scene.
One way I can think of is to use some sort of octree and split all the triangles. This should be fast, but for detailed terrain the size would get very big quickly.
Thanks!
