Ah OK, the render to texture idea is maybe a good alternative. Do the RTT affect the performance?
My idea was a observer pattern. The camera settings are in a subject object and the osg::Camera is in the observer object. When the settings to be change the subject notify the observer (cameras with different viewports). But I think it is time consuming. Do you think, the RTT is the better way?
