I'm interested in reading up on hemispherical lighting, the kind of thing which gets called a Sunlight in some 3d packages. I'm particularly interested in reading related to using it for lightmapping. I have a decent algorithm to UV map an abritary mesh and create a reasonably tightly packed lightmap, but raycasting isn't particularly the effect I want, and I doubt hemispherical lighting is fundamentally much more difficult once you understand but I can't find anything about it. Perhaps it has another name I don't know about.
I guess it's not a million miles away from ambient occlusion mapping, but I don't think it's quite the same thing. Anyway, any articles or tutorials would be very helpful. If there's code or a library about then so much the better, as I don't really have the time to learn how to write my own lightmapper but I will if I have to.
