[osg-users] Creating a glowing sun in scene

[David Heitbrink]

I think looking at the osgblenddrawbuffers or osgmultiplerendertargets might be a good start. Neither of these are really doing what you are aiming for, but  shows you how to add the color buffers and shaders.

You might also look at the OSGPPU project. It I think it has some more relevant examples, although the OSG PPU project is not being actively maintained at this time.
