Hello, I use osg long time ago, but I think I don't understand the light concept. Can everyone explain me the correct use of Light, LightSource and ShadowMap? In previous implementations I put the Light into the LightSource and the LightSource into my scene graph. Now my root node is a

Hi Manish, I'm a bit confused a bit by your post, you seem to have included a lot of code for what is potentially just a very simple question, so it makes me wonder if you aren't asking something else... To use the smoothing visitor you simple do: osgUtil::SmoothingVisitor sv;

Re: [osg-users] Rendering performance gain on 2 different Systems

Hi Felix, The Intel embedded graphics chipset is going to be limited by different things than NVidia graphics card. The Intel chipset will be limited far more by transform and fill than the graphics card so optimizations in the way the data is stored and passed to OpenGL will have less impact.
