Hi all, I've given a trick subject. I don't have any suggestions, but I am looking for some. I have a HUGE terrain which uses paged LOD. I've been trying to implement shadows on my scene using this terrain, but the performance is terrible. Using ShadowTexture technique drops my frame-rate from 60+ to low 30's to high teens. Moreover, ShadowTexture doesn't work very well on my models, because depending on my camera's position, certain geometries of my models get blackened (Any ideas why this ugly artifact occurs with ShadowTexture?). Finally, using ShadowMap puts OSG on its knees at ~6 fps. Is there a way to implement shadows efficiently in a situation like this one? Thanks,
-Jose P.S Perhaps worth mentioning: If I use the 'cessna.osg' on my scene, OSG goes crazy and flashes chunks of the cessna geometry all over the screen. It is hard to capture for a screen-shot, but I wonder if anyone has ever gotten this. To replicate, put cessna (particularly with ShadowMap), on a scene together with a big paged LOD terrain (it doesn't happen with other models - only with cessna.osg so far). This is not for just my application, it happens in OSG viewer. If someone is interested in seeing this, I could make a bigger effort to take a screen-shot. _______________________________________________ osg-users mailing list [email protected] http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
