[osg-users] bounding box collisions (without osgbullet)

[Trajce Nikolov NICK]

Hi Sebastian,

it is for simulation, i have a moving entity and a terrain (with buildings
etc). Now I am not after triangle level intersection, but after Entity BBox
collision with the terrain (enough is true false). I was thinking to do it
really very simple by having LOS rays from the entity center to the corners
of the BBox. The entity can move in any direction
