HLSL2GLSL ready to convert HLSL shaders to OpenGL ES Shading Language shaders

HLSL2GLSL is an open source tool that translates DirectX 9 HLSL shaders into the OpenGL Shading Language (GLSL). The new v0.9 has been released with many options that will support shaders that are compatible with OpenGL ES 2.0 (OpenGL ES 2.0 implementations are on track for release in early 2007). Specifically, HLSL2GLSL can generate shaders that use only user attributes and user varyings (required by OpenGL ES Shading Language v1.00). In addition, it can prepend a default precision qualifier as required by ES v1.00 for fragment shaders.Read More
