Ya I was thinking that. It just made me think there is no way that is how it works. That would be basically race tracing if a quad covered the screen. And gonna have to disagree with it being expensive on the gpu at least for what I showed which was more of mini rendering engine than shader. And as for using it in the fragment shader guess I'd just experiment a lot with max steps and what not and actually profile it. Thanks for the info anon
