OpenGL SLが出れば，Cgは終わり
The OpenGL Shader Language is a C-like language intended to make programming today's and tomorrow's graphics cores easier as they become ever more complex. Shader code can be written in OpenGL SL and then compiled into any given graphics chip's native machine code. Nvidia's entry into the field is Cg. Nvidia's arch-rival, ATI, favours OpenGL SL and is working to integrate it into its RenderMonkey graphics development suite.
