Carmack and Megatexture

Next game from Id Software will be released this year: Enemy Territory: Quake Wars. I’m writing about this because John Carmack seems to have implemented an interesting technology for terrain rendering. What I can deduce reading this interview and lot of forums in internet is that it is a similar algorithm as the one described by Arul Prakash and Hugues Hoppe in the last GDC: Geometry Clipmaps, an unique and huge texture that is smoothly interpolated (and may be proceduraly generated) in the GPU. The name given by ID Software is Megatexture (contributing to the MegaHype surrounding John Carmack, of course, a deserved one)
