Hi Paul, I'm confused between static and dynamic objects. Does dynamic object mean the rigid body dynamic object and the dynamic world? I thought dynamic objects were only needed if I had to get inertia and motion states properties to the objects. In my case I only need to test if the 3D models collide among themselves so their movement(translations etc) could be restricted.
Therefore I was under the impression only the collision library (osgbCollision) would suffice my purpose. However I'm still missing on something and unable to get it work.
