3Dlabs ships OpenGL Shading Language compiler

3Dlabs has released the front-end OpenGL Shading Language compiler as an open source project (here). This is for 3Dlabs’ Wildcat VP line of cards (which will also require the OpenGL 2.0 drivers). This is just the front-end compiler – it reduces the shader to an intermediate representation. A target specific back-end compiler is required to generate machine code for a specific graphics card. It’s interesting to note that despite the ATI-3Dlabs OpenGL lovefest at last year’s Siggraph, we see no RenderMonkey stuff from 3Dlabs, nor any OpenGL 2.0 stuff from ATI.
