I recently read this GPU GEMS 3 article Volumetric Light Scattering as a Post-Process. I like the idea to add volumetric light property to realtime render i'm working on. Question is will it work for multiple lights? Our renderer uses one render pass per light and uses additive blending to sum incoming light.

I'm mostly convinced that it have to work nice. Do you agree? Maybe there can be problem where light rays crosses each other.
