OpenGL News Archives
We have some good news and some bad news. The year-end target release date for Vulkan will not be met. However, we are in the home stretch and the release of Vulkan 1.0 is near!
A more detailed update is available on the Vulkan ecosystem page.
Computations & Graphics, Inc. is excited to announce the release of its flagship product Real3D-Analysis V11. With its graphics engine based on OpenGL, Real3D-Analysis is a very user-friendly, robust and affordable finite element and structural analysis software. It features a unique 128-bit floating point (quad-precision) solver, fast sparse solver and extremely interactive graphical user-interface for input and output.
AMD has announce it will start rolling out in January an open source set of tools called GPUOpen. The “All Open” stack will contain open source modules for two parallel stacks, each containing modules for OpenGL graphics, motion video codecs, and OpenCL GPU computation. The “Professional/Gamer” stack will include the open source motion-video module and a closed source OpenGL module. Its final OpenCL module will support both OpenCL and Vulkan. Linux will gain access to a full open source, high-performance driver stack, with the only constraint being that developers must use Vulkan instead of the older OpenGL.
SoftIntegration, Inc. announced Ch 7.5.1 and Embedded Ch 7.5.1 are available. Ch is the most complete cross-platform embeddable C/C++ interpreter and OpenGL is supported. Ch 7.5.1 is a major release with many new features to make Ch especially appealing for beginners in elementary schools, middle schools, high schools, as well as colleges to learn coding, math, and robotics.
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.
The latest driver update covers GeForce 8 and 9 video cards allowing them to continue using hardware with modern OSes. From the changelog ““Fixed a bug that could cause texture corruption in some OpenGL applications when video memory is exhausted by a combination of simultaneously running graphical and compute workloads.”
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 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.
