This might be a simple question (something quite basic for a graphics engine)...
How do I get the normalised rotation vector for a given mesh? Currently I'm using a dummy ObjectContainer3D placed as a child 1 unit in front of my mesh. When I rotate the mesh, I just need to get mesh.dummy.scenePosition - mesh.scenePosition .. which gives me the normalised rotation vector. I thought there might be a better/faster way. Cheers for any help.
