OK,
I've tried redefining the manipulator directly and I tried with the main
camera. Both methods fail to actually update the trackball's center & radius.
Ex:
m_rpMainCamera->setViewMatrixAsLookAt( vnew_eye, vnew_center, vnew_up );
or...
m_rpTerrainManipulator->setHomePosition( vnew_eye,v new_center, vnew_up );
What's the recommended way to do this?
Thanks,
