Beyond Porting: How Modern OpenGL Can Radically Reduce Driver Overhead

Jul 16, 2014 | Categories: Developers | Comments

With SIGGRAPH 2014 around the corner, I felt it fitting to post this Steam dev days talk from earlier this year, featuring John MacDonald and Cass Everitt:

KDE Plasma 5 desktop is fully OpenGL accelerated

Jul 16, 2014 | Categories: Developers | Applications | Comments

KDE proudly announces the immediate availability of Plasma 5.0, providing a visually updated core desktop experience that is easy to use and familiar to the user. Plasma 5.0 introduces a new major version of KDE’s workspace offering. The new Breeze artwork concept introduces cleaner visuals and improved readability. Central work-flows have been streamlined, while well-known overarching interaction patterns are left intact. Plasma 5.0 improves support for high-DPI displays and ships a converged shell, able to switch between user experiences for different target devices. Changes under the hood include the migration to a new, fully hardware-accelerated graphics stack centered around an OpenGL (ES) scenegraph. This allows offloading computationally expensive graphics rendering tasks onto the GPU which frees up resources on the system’s main processing unit, is faster and more power-efficient.

OGLplus 0.48.0 released

Jul 14, 2014 | Categories: Developers | Comments

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

CeedGL library encapsulates OpenGL objects into Objective-C objects

Jul 11, 2014 | Categories: Developers | Comments

CeedGL is a library that encapsulates OpenGL objects into Objective-C objects. It does not attempt to force a coding style or to define a specific scene graph, but instead aims at making it easier to work with OpenGL from Objective-C.

Khronos Group announces WebGL Widget Contest

Jul 07, 2014 | Categories: General | Developers | Comments

Help Khronos get a more interesting WebGL widget on Khronos.org and maybe even win a prize by entering the WebGL Widget Contest. We will choose the coolest widget that best shows off WebGL technology. Then we’ll post the winning entry on the Khronos website with a link back to the winner’s website, and the winner will receive a Mali-based device from ARM. The winner will be announced at our WebGL BOF at SIGGRAPH.

Anton’s OpenGL 4 Tutorials for Kindle

Jul 07, 2014 | Categories: Developers | Comments

Anton’s OpenGL 4 Tutorials is a practical guide to starting 3d programming with OpenGL 4. It will suit anyone learning 3d programming that needs a practical guide with some help for common problems. This book is a collection of worked-through examples of common real-time rendering techniques as used in video games or student projects. Along with some chapters and short articles for Tips and Tricks - not-so-obvious techniques that can add a lot of value to projects or make it easier to find problems.

June updates to Magnum C++11 and OpenGL/GLES/WebGL graphics engine

Jul 07, 2014 | Categories: Developers | Applications | Comments

Magnum is multiplatform 2D/3D graphics engine written in C++11 and modern OpenGL, released under MIT license. The June snapshot brings experimental Android support, windowless applications and command-line tools also on Windows and OS X, OBJ importer plugin, improved texture and mesh handling, multisample textures, instanced rendering, more robust support for driver detection and workarounds, ability to combine pure GL API calls with Magnum code and build system and documentation enhancements.

Khronos announces OpenGL ES 3.1 Conformance Test

Jun 06, 2014 | Categories: Developers | Comments

The Khronos OpenGL ES Working Group is pleased to announce the launch of the OpenGL ES 3.1 Adopter Program. The program gives participants access to the OpenGL ES 3.1 conformance test, and allows them to submit implementations for conformance certification. The OpenGL ES 3.1 conformance test builds on the latest version of the ES 3.0 test, which includes greatly enhanced shading language coverage contributed by drawElements Ltd. It adds eighteen new test categories covering the new features of ES 3.1, including compute shaders, image and buffer object load/store, atomic operations, and indirect drawing.  In addition to the conformance test, the working group has released updated API and shading language specifications, containing many corrections and clarifications.

More information about the Adopter program can be found in the Adopters’ Agreement and the . The updated specifications are available in the Khronos OpenGL ES Registry.

Flash Is Dead … Long Live WebGL

Jun 03, 2014 | Categories: Developers | Applications | Comments

Recent research shows that WebGL is now supported on more devices than Flash. It’s the bigger platform. In fact, WebGL powered HTML5 is now the largest platform on the planet for interactive browser graphics. Now that WebGL is available on IE and Safari as well, we should see WebGL become even bigger. Long live WebGL!

NVIDIA releases updated driver with OpenGL fixes and support for new GPUs

May 31, 2014 | Categories: Developers | Comments

NVIDIA released an updated driver for the Linux X64 (AMD64/EM64T) display driver. Along with additonal support for many NVIDIA GPUs, there are also a few fixes for OpenGL including: fixed a performance regression when running KDE with desktop effects using the OpenGL compositing backend; fixed a regression that could cause OpenGL rendering corruption on X screens with 30 bit per pixel color; Added support for the GLX_EXT_stereo_tree extension and added support for the GLX_NV_delay_before_swap extension.

OGLplus 0.46.0 released

May 29, 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 automates resource and object management, error handling and makes the use of these libraries in C++ safer and more convenient. This release also brings a major re-implementation of several key parts of the library.

OpenGL compatible Image libaries

May 28, 2014 | Categories: Developers | Comments

Looking for an image library for your OpenGL project? We’ve got you covered. Just added is LodePNG: a PNG image decoder and encoder, all in one, no dependency or linkage to zlib or libpng required. It’s made for C (ISO C90), and has a C++ wrapper with a more convenient interface on top.

Qt and OpenGL Part 1: Loading a 3D Model with Open Asset Import Library (Assimp)

May 27, 2014 | Categories: Developers | Comments

The first in a series to cover using OpenGL with Qt. This instalment looks at how to use Open Asset Import Library (Assimp) (1) to load 3D models from some common 3D model formats. The example code requires Assimp version 3.0. The code also uses Qt for several convenience classes.
