Re: [osg-users] Help: how to rotate view camera 90 degrees in relationship to terrain

Hi Allen, the problem with setMatrix is that it cannot fully encapsulate the state of the manipulator. Internally the manipulator (trackball) uses a distance, rotation and center, but all these variables do not fit into a matrix. The manipulator can calc a matrix from the internal variables,
