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.
The open source C++ creative coding toolkit Cinder has recently released version 0.9. This release adds support for OpenGL ES 2 and ES 3, in addition to the latest desktop versions of OpenGL. Cinder supports targeting Windows, OS X, iOS and WinRT, with Linux and Android support under active development. In addition, this release adds support for Google’s ANGLE project, allowing deployment of OpenGL ES 3 applications on Windows and WinRT through a DirectX emulation layer. Cinder is released under the BSD License and is used by professionals in the creative and technology industries for everything from interactive installations to user interface prototyping to live concert visuals.
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 There are many cases where OpenGL still performs better despite the fact that Apple’s implementation is out of date, and there are other cases where Metal might perform a little better but may not be worth the extra programming complexity that comes with low-overhead APIs.
The Brenwill Workshop Ltd. announced that they have added support for OS X to their MetalGL product, an implementation of OpenGL ES that runs on Apple’s Metal graphics framework. With a fast implementation of OpenGL ES on OS X, developers will find it easier to migrate OpenGL ES games and apps from iOS to OS X, and web browsers can leverage MetalGL to improve the performance of WebGL on OS X.
The 47th installment in a series of tutorials dedicated to promoting modern OpenGL development, with a focus on version 3.x and beyond. This tutorial demonstrates how to implement the shadows with directional lights using orthographic projection.
NVIDIA’s developer twitter feed announced an updated driver (including Windows 10 now) supporting all the OpenGL 2015 extensions, OpenGL ES 3.2 context support, and two new ES extensions to fill gaps in ES’s functionality, EXT_blend_func_extended and EXT_multisample_compatibility. And this presentation explains the OpenGL 2015 extensions.
To meet growing demands for professional OpenGL trainings KDAB has opened a new dedicated training facility in the UK with easy access from Manchester airport. Sign up now for our inaugural Modern OpenGL training starting on 28th September and learn modern OpenGL and GLSL via a combination of instructor led lessons, hands-on exercises and over 100 examples.
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.
The Khronos Group BOF Blitz is live streaming all BOFs. Starting with “Accelerating Vision Processing” at 1PM PT followed by “Heterogeneous Computing” at 2PM and “3D Web Graphics” at 3:45PM. Finally, at 5:30PM there will be the “3D Graphics API State of the Union” BOF which will include Vulkan:
The NVIDIA Developer Tools team is proud to announce the production release of the NVIDIA Linux Graphics Debugger, a 3D graphics development tool that allows developers to debug and profile OpenGL 4.x on Linux, enabling professional graphics developers to get the most out of their NVIDIA GeForce and Quadro GPUs on a variety of Linux distributions.
The Khronos Group announced significantly expanded scope and momentum for its family of open standard 3D graphics APIs. Vulkan™, the new generation API for high-efficiency access to graphics and compute on modern GPUs, is on track for implementation and specifications later this year. It has received support from Android, SteamOS, Tizen, and multiple Linux distributions, including Ubuntu and Red Hat. The new OpenGL® ES 3.2 specification absorbs AEP (Android Extension Pack) functionality to enhance pervasive graphics capabilities across mobile, consumer, and automotive devices. A set of OpenGL extensions will also expose the very latest capabilities of desktop hardware.
To coincide with the release of OpenGL 2015 ARB extensions and OpenGL ES 3.2, NVIDIA is pleased to announce our OpenGL 2015 beta drivers are available for immediate download for Windows and Linux. Further details and driver downloads are available at the NVIDIA OpenGL website.
GLEW is a cross-platform (Windows, Linux, Mac, Unix) open-source C/C++ extension loading library for OpenGL. GLEW 1.13.0 adds support for new ARB, KHR, INTEL, NV and OVR extensions.
