IWOCL 2014: 5 days left to register!

May 06, 2014 | Categories: Developers | Comments

There are just 5 days left to register for the International Workshop on OpenCL (IWOCL), to be held in Bristol, UK on May 12th & 13th next week! Over 100 OpenCL practitioners are expected to attend, including leading members of the academic and industrial OpenCL community. For a complete list of technical talks and tutorials see the website.

GameWorks provides advanced multi-platform OpenGL samples

Apr 29, 2014 | Categories: Developers | Comments

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 | Categories: Developers | Processors | Comments

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 | Categories: Developers | Comments

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 | Categories: Developers | Comments

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.

Khronos update OpenGL 4.4

Mar 19, 2014 | Categories: Developers | Comments

The Khronos Group has released an update to OpenGL 4.4. Included are many small bugfixes, clarifications and general cleanup.

OGLplus 0.43.0 released

Mar 19, 2014 | Categories: Developers | Comments

OGLplus is a collection of open source, cross-platform libraries which implement an object-oriented facade over the modern OpenGL and also OpenAL and EGL C-language APIs. It provides wrappers which automate resource and object management, error handling and make the use of these libraries in C++ safer and more convenient.

Khronos Releases OpenGL ES 3.1 Specification

Mar 17, 2014 | Categories: Developers | Comments

The Khronos Group has announced the immediate release of the OpenGL ES 3.1 specification, bringing significant functionality enhancements to the industry-leading, royalty-free 3D graphics API that is used on nearly all of the world’s mobile devices. OpenGL ES 3.1 will provide the most desired features of desktop OpenGL 4.4 in a form suitable for mobile devices.

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

Mar 11, 2014 | Categories: Developers | Applications | Comments

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.

Khronos Meetups at GDC 2014 next week, reserve your seat today!

Mar 10, 2014 | Categories: Developers | Comments

With only a few days remaining to reserve a seat, the Khronos Group meetups at GDC 2014 are quickly approaching. We’re looking forward to seeing everyone for lots of learning, prizes and refreshments. Complete details are online. Our seven meetups include OpenCL and WebCL, OpenGL ES and OpenGL, WebGL, COLLADA with glTF and OpenVX, Camera and StreamInput. As well a joint press conference with the PC Gaming Alliance will take place on March 19th 2014, with lots of interesting news for everyone. There will be many speakers from many companies. This is a not to be missed 2 day event for anyone going to GDC.

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

Mar 10, 2014 | Categories: General | Comments

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.
