Thanks for your quick response, Gordon slowness must be directly related to the number of vertices and not to the rendering. I gain more fps with "Release", SoftwareGL (VirtualBox) than with "Debug", GeForce Go 7400.
Despite of how many vertices are culled away (used a ClipNode for that) I got a 3-5 fps when rendering my model (4MB osg). In release mode fps is maxed out to 60 fps but would be 400 or so. My model is a building which contains lots of transparent polygons. I disable texturing and lighting and set the BlendFunc to (ONE,ZERO) via SetStateSet. After all I optimize the geode, don't know whether the osgViewer class does this already, but it seems the bottleneck is somewhere else :( Models with lower polygon count (e.g. cow.osg) achieve maximum fps. greetings, Stefan >8^) PS: I've build the release with debugging info already, but they aren't linkable to "Debug"-Qt neither. _______________________________________________ osg-users mailing list [email protected] http://openscenegraph.net/mailman/listinfo/osg-users http://www.openscenegraph.org/
