Hi, to do a post-processing effect without using Render To texture, I know two choices. First, you can implemented your own effect with osgFX (see osgFX::Cartoon). Or, in your scene graph, you add a quad (with an orthogonal projection before) at the end, and create your drawable::callback. In the drawImplementation method, you can do an osg::Image->readPixels(), to fill your texture, before calling the drawable->drawImplementation(). I hope this can help you good luck

I need to implement post process effect. I have to change the color of rendered picture depending on the depth buffer. So I wrote shader for my post process, but as input it needs the rendered image and depth buffer. Is there some another technique to render post process as differing shading? I looked at osg prereder and reflection examples, but I do not have real strategy. :-( Help!!! _____________________________________________________________________ Der WEB.DE SmartSurfer hilft bis zu 70% Ihrer Onlinekosten zu sparen! http://smartsurfer.web.de/?mc=100071&distributionid=000000000066 _______________________________________________ osg-users mailing list osg-users@openscenegraph.net http://openscenegraph.net/mailman/listinfo/osg-users http://www.openscenegraph.org/
