GameWorks provides advanced multi-platform OpenGL samples

Apr 29, 2014

NVIDIA GameWorks provides OpenGL code samples that build from the same source code for Android, Windows, and Linux platforms. Examples demonstrate bindless graphics, path rendering, tessellation, instancing, multi-draw indirect, and more. Now you can write advanced OpenGL programs with a common user interface for all these platforms.

AMD Posts Catalyst 14.4 Release Candidate Drivers with OpenGL 4.4 support

Apr 28, 2014

Coinciding with this week’s launch of the Radeon R9 295X2, AMD has posted their latest Catalyst drivers, now at version 14.4. These drivers bring support for OpenGL 4.4 to AMD’s GPUs, which among other additions sees support for sparse textures (partially resident textures) and buffer storage objects for use with processors that have unified memory between the CPU and the GPU. Product is based on a published Khronos Specification, and is expected to pass the Khronos ConformanceTestingProcess. Current conformance status can be found at www.khronos.org/conformance.

AMD Publishes New OpenGL 4.4 Extensions

Apr 10, 2014

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

Mar 25, 2014

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.
