AMD published two new OpenGL extensions today, both of which are written against the OpenGL 4.4 specification. The first extension, GL_AMD_gpu_shader_int64 was developed based on the NV_gpu_shader5 extension to allow implementations supporting 64-bit integers to expose the feature without the additional requirements that are present in NV_gpu_shader5. The second extension is GL_AMD_transform_feedback4. This second extension enhances OpenGL’s transform feedback in allowing multiple TF streams to be captured and allows any combination of streams to be rasterized.

KlayGE Announces DXBC2GLSL, a HLSL bytecode to GLSL compiler

We are glad to announce the DXBC2GLSL, an open source library that convert the HLSL bytecode (DXBC) to GLSL. The inputs of DXBC2GLSL is SM5 bytecodes (also compatible to SM4). After parsing, input variables, output variables, texture declaration and shader instructions can be retrieved. The output GLSL can be VS/PS/GS in OpenGL 2.0 to 4.4. HS/DS/CS support, and an OpenGL ES version is currently under development. Theoretically, this framework can even convert compute shader to OpenCL.
