John Carmack, of DOOM, Wolfenstein, and Quake fame, has spoken out on the issue of Direct3D vs OpenGL in an interview with the folks at bit-tech. Check out the article here. Note that Carmack is still using OpenGL in his game engines because of cross-platform compatibility reasons, but prefers Direct3D’s more modern API.
It’s sad to see OpenGL in such a state of disrepair that even a contributor (id Software) to the specification denounces the standard.
P.S. Happy π day.
