HI all, I am currently trying to manually attach a camera behind a node containing a transformed object mesh. I would like the camera to translate and rotate identically to my object.
I am setting the transform matrix of the node by calling obj_transform_matrix.makeLookAt(OBJECT ROLL VECTOR, OBJECT POSITION COORDS, OBJECT YAW VECTOR). I know that the camera should be a given number of units (let's say 40 units) behind the object on the eye vector, so I then set my camera matrix to camera_marix.makeLookAt(OBJECT ROLL VECTOR, OBJECT POSITION COORDS - OBJECT ROLL VECTOR * 40, OBJECT YAW VECTOR). I then finalize the camera matrix to camera_matrix.inverse(camera_matrix) * osg::Matrixd::rotate(-M_PI/2.0, 1, 0, 0). Is this logic sound for what I am trying to do?
