Yeah, it's not ladder. It's cable tray in the power plant. . In fact, I used not more than 1000 cylinders, osg runs very slow. I ignore the cylinders, it gets much faster.
then I have to disable shadow, osg::ref_ptr<osgShadow::SoftShadowMap > ssm = new osgShadow::SoftShadowMap; // float bias = ssm->getBias(); // ssm->setBias(bias*2.0); // mShadowedSceneRoot->setShadowTechnique(ssm.get()); // mShadowedSceneRoot->setReceivesShadowTraversalMask(ReceivesShadowTraversalMask); // mShadowedSceneRoot->setCastsShadowTraversalMask(CastsShadowTraversalMask); the program runs fast again. So I enable shadow again, and disable the cylinders // setNodeMask(CastsShadowTraversalMask); the program still slow. Maybe I can't draw my power plant prefectly, without shadow. And would you please answer my another question in the other article, it's still about the power plant. thanks. ------------------ Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=64464#64464 Attachments: http://forum.openscenegraph.org//files/cabletray_292.jpg _______________________________________________ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
