A C++ library that takes GLSL shaders, does some GPU-independent optimizations on them and outputs GLSL back. Optimizations are function inlining, dead code removal, copy propagation, constant folding, constant propagation, arithmetic optimizations and so on. Quite a few mobile platforms are weak ... [More] at optimizing GLSL shaders; and unfortunately they also lack offline shader compilers. So using a GLSL optimizer offline before can make the shader run much faster on a platform like that. Almost all actual code is Mesa 3D's GLSL2 compiler; all this library does is spits out optimized GLSL back. [Less]

HLSL to GLSL shader language translator. A continued development from ATI's HLSL2GLSL project.
