Hi, I would like to use an osgViewer::Viewer which should render to a constant aspect ratio and fill the rest of any rendering window with black in any case; also on resizing.
For that matter, I have implemented an updateViewport() method that resizes my Viewport centered in the correct aspect ratio and according to my current window size. This works in general, but two questions remain: - I have called this method both as an event handler on window resize events, and as a ResizeCallback in my GraphicsContext. Where is the correct place to put this? If I replace the ResizeCallback of the Context, do I have to take care of more things than just setting the viewport correctly? - On resize in either case, ghost images of the rendering to the former window size remain. What do I have to do to flush anything that happened before, and just render black in the surrounding area of my viewport? Also interesting: if I render to texture in my application, and use the frame buffer as target, those areas that are not overwritten by the actual rendering viewport still show the texture that is rendered to in RTT. In all cases, what I want is just plain black. ;) Thanks a lot, Alex. _______________________________________________ osg-users mailing list [email protected] http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
