Just a note.

I saw that trick for the first time on one of Humus demos: http://www.humus.ca/ That was long time ago, and I cannot tell exactly which one anymore... I think he was storing distances on cubemaps. Anyway, since he works at ATI I imagine he got it right. Hmm… I saw that trick for the first time on one of Humus demos:
