Carmack backs OpenGL in shader wars

Game god John Carmack has given OpenGL his blessing in the ever-thickening shader wars. Carmack says that given the 3Dlabs P10 card, he opted to use the OpenGL 2.0 extensions for the shader path, even though the Nvidia Cg extensions offered “the most expedient choice”. And the port went so well, he writes in the latest addition to his .plan file, he’s committed to using OpenGL as the back end for all implementations of Doom 3.0. It isn’t so much a shader war (not our term) as a language war, and Carmack sees such higher level languages as Nvidia’s Cg as inevitable for graphics developers.
