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.

Shaderific 3.2 adds support for OpenGL ES 3.0 and GLSL ES 3.0

Shaderific version 3.2 is now available. Shaderific is an educational app for iPad, iPhone and iPod touch that makes it possible to write, compile and test OpenGL ES 2.0 and OpenGL ES 3.0 shader programs directly on any iOS device. Version 3.2 adds support for OpenGL ES 3.0 and GLSL ES 3.0. The new capability of using 3D textures in a shader program is demonstrated by a shader that generates a procedural fire effect based on a pre-calculated 3D noise texture. A new blending mode allows rendering of multiple blended objects. The blending factors and blending function can be customized without interrupting the rendering loop.

How do features make it into OpenGL? The process in the Khronos Group

Graham Sellers has written a post that looks forward into the future of OpenGL. Answering questions like how do features make it into OpenGL, who decides what the functions should be called, and what goes in the core specification and what remains an extension. In his post, Graham talks about the process at Khronos — the standards body that produces the OpenGL specification, its members, the process of creating and publishing and suggests how you, as a user, are able to contribute.
