Hello, I have a static scene that my program visualizes using a trackball manipulator. I would like to update the rendering only when the camera moves, that is the user moves it with the mouse or the camera is spinning around. I am using a Qt wrapper so I know how to stop the refresh by simply stopping the QTimer in there, and I also know how to update upon user interaction since Qt gives very nice messages, what I don't know is: how can I know if the trackball manipulator is making my camera spinning around or not? Maybe osgGA::TrackballManipulator::getRotation() encodes in some way the rotation velocity? or it's just the current rotation of the camera?
Thanks, Michele _______________________________________________ osg-users mailing list [email protected] http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
