osgHello how do the following options affect the render performance? especially the culling threshold is of interest, as i'm making heavy use of occlusion culling.
_renderAction->setSortTrans(0); _renderAction->setZWriteTrans(0); _renderAction->setLocalLights(0); _renderAction->setCorrectTwoSidedLighting(1); _renderAction->setOcclusionCullingThreshold(0); // hierarchical multi frame are there any other options i should consider for the optimization of rendering performance? my scene (citymodel) contains about 100k nodes, 16mio (transformed) vertices and makes heavy use of instancing (reuse of geocores) and material groups. with the camera on eyelevel and activated hierarchical multiframe occlusion culling the framerate is about 24fps on a nvidia 8800 ultra. render resolution is 800x600. do you have general optimisation ideas or is this the maximal framerate i can expect? when does the use of VBOs make sense? displaylist caching? thanks & cheers, simon ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
