Hello! For some weeks I am working on a program with atmospheric scattering to render a nice sky and add scattering to my terrain. My code is based on the O'Neil CPU code ( http://www.gamedev.net/columns/hardcore/atmscattering/ ). My program is already working but I have 1 or 2 graphic bugs and now Im not sure if I did everything right. So I wondered if anyone here has implemented O'Neil Atmospheric Scattering and wants to talk about this topic with me? Thanks:)

I've not implemented myself, but you can find a complete implementation in http://filougk.blogspot.com/ maybe that can help you...

I already have talked to this guy but unfortunately he implemented the GPU Version of O'Neil Scattering, so it doesnt help me much.

O'neil himself has a complete implementation on his home web page for both the GPU and the CPU version.
