Sorry for confusing, I thought the job of exchanging a color target in a static rendering context is common enough. My bad. I have a GIS environment with mixed flat (2d) and 3d geometry. I want to pre-render the flat geometry together with the ground images into the final surface gl-textures, which I then use in the 3d scene-graph. The 2d geometry is managed by a separate scene-graph, which I use to generate the ground tiles by using a RTT camera. The ground-tile rendering happens by repositioning the RTT camera over the dirty area and passing the related texture object reference to the CullCallback, which tries to replace the color buffer binding with the passed texture before the camera does the rendering. Then I call frame() on the groundViewer instance to trigger the rendering. It all works, but the cheap color buffer changing. Regarding the documentation, it would help a lot, if the member-functions and their parameters would be documented (as usual for a public API). I know, everybody has always less time for that, but it would be a great help for all the OSG users, especially for the newbies. ------------------ Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=47710#47710 _______________________________________________ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
