Khronos Amsterdam Chapter hosting an OpenGL beginners training series

Learning OpenGL from scratch is easier in a group - and that is exactly what we’re going to do. Learn with us the steps to program an OpenGL program that works on Android, Windows and Linux. All you need to know is basic programming in C, and have good experience in another language. Around 10 lessons are planned for January til March.

MetalGL Now Supports OS X for Low-latency OpenGL ES rendering using Metal

The Brenwill Workshop Ltd. announced that they have added support for OS X to their MetalGL product, which seamlessly brings the performance of Metal to OpenGL ES games and applications on iOS, and now OS X. MetalGL is an implementation of the OpenGL ES 2.0 API that runs on Apple’s Metal graphics framework on compatible iOS and OS X devices. MetalGL unleashes the power of Metal’s low-latency rendering to let OpenGL ES games and applications perform up to 3x the number of draw calls, and benefit from the advanced tools available for the Metal development ecosystem, all without changing the way the game or app use OpenGL ES.

Khronos Finalizes glTF 1.0 Specification

Khronos announced today that the glTF™ 1.0 (GL Transmission Format ) royalty-free specification for transmission and loading of 3D content has been finalized for Ratification and is immediately available for use by tools and application vendors.  glTF is an efficient, interoperable asset delivery format that compresses the size of 3D scenes and models, and minimizes runtime processing by applications using WebGL™ and other APIs.  glTF also defines a common publishing format for 3D content tools and services. More information on glTF specifications and activities.

Arstechnica Metal vs OpenGL benchmark - perhaps not quite what you expected

The benchmarks use Manhattan and T-Rex, both high-level tests that render a full 3D scene. Manhattan is the more demanding of the two, and it uses more complex lighting and effects. The ALU, Driver Overhead, and Texturing tests are low-level ones that attempt to measure some specific aspect of graphics performance. For whatever reason, the OpenGL version of GFXBench consistently beats the Metal version in the T-Rex, ALU, and Texturing tests. And usually it’s not winning by a little, it’s winning by a lot. There are many cases where OpenGL still performs better despite the fact that Apple’s implementation is out of date, and there are other cases where Metal might perform a little better but may not be worth the extra programming complexity that comes with low-overhead APIs.

AMD demonstrated hardware-based GPU virtualization solution with OpenGL support

AMD demonstrated at VMworld 2015 their hardware-based GPU virtualization solution, the AMD Multiuser GPU. This new solution from AMD enables a virtualized workstation-class experience with full ISV certifications and local desktop-like performance. With the AMD Multiuser GPU, IT pros can easily configure these solutions to allow up to 15 users on a single AMD GPU. Created for GPU-accelerated workflows such as GPU compute and OpenCL, the AMD Multiuser GPU is designed to overcome the limitations of software-based virtualization such as reduced end-user performance. Users have access to native AMD display drivers for OpenGL, DirectX and OpenCL acceleration, enabling work without restrictions. Additional AMD Multiuser GPU features include Compute capabilities based on OpenCL supported by industry leading GPU virtualization; Full feature set support including DirectX 12 and OpenGL 4.4 and OpenCL 2.0 acceleration support.
