The new version of Piccante, a C++11 multi-platform (windows, mac os x, and linux) open-source (MPL license v2.0) imaging library, is now out! The new version provides a better support for OpenGL 4.0 Core Profile and novel algorithms on the GPU: improved memory management, image operators, better image statistics via redux, exposure fusion, Drago and Reinhard tone mapping operators, push-pull, edge-aware filtering, etc.
KDAB are rewriting the Qt3D module of Qt 5 to provide an easy but flexible API for easily getting 3D content into your Qt applications using either C++ or QML. Qt3D is built on top of OpenGL and OpenGL ES and provides a data-driven renderer configuration. One of the biggest driving factors behind the design of Qt3D 2.0 is the ability to configure the renderer in order to accommodate custom rendering techniques. In this blog post I will explain how to render a scene in Qt3D with shadows.
NVIDIA has provided a set of OpenGL and OpenGL ES examples illustrating various techniques and features to use in your own code. The GameWorks examples are aimed more at game developers, and run on Windows, Linux and Android. They are broken down by topic. The “NVIDIA Professional Visualization” set of examples are OpenGL based, and aimed more at the professional workstation developers. The repository is new, so expect more samples to be published soon. Linux support is being worked on. You can find the examples on Github.
GLFW is a library for portable OpenGL and OpenGL ES desktop application development. It manages windows, contexts, monitors and input. Version 3.1 adds improved documentation, support for custom cursors, file drop events, main thread wake-up, single buffered windows, fixes for a large number of bugs and more.
Have you heard about the next generation OpenGL initiative? Khronos Group is designing a ground-up, cross-platform API to enable direct access to modern GPUs. We think this is a pretty big deal and we are seeking community input on the name for this new API. Please take a few minutes to take our survey. Your input along with that of others will help guide the naming of this significant initiative.
Remember when mobile devices required you to compromise with a less-than-state-of-the-art OpenGL ES implementation? Those days are past; now you can develop for a mobile device with complete feature support for state-of-the-art OpenGL 4.5, no compromises or deprecation and all the NVIDIA OpenGL extensions available too. The latest Shield Tablet software upgrade 2.1 now includes full OpenGL 4.5 support.
NVIDIA announced the new Tegra X1 mobile processor. Both OpenGL 4.5 and OpenGL ES 3.1 are to be supported. Utilizing NVIDIA Maxwell architecture and with 256 GPU cores, a 64-bit CPU and 4K video capabilities.
G-truc has updated his OpenGL 4 hardware matrix. Available online in PDF format. It has been six months since the last update, nevertheless, the ecosystem hasn’t evolved so much with no change for Apple despite MacOSX 10.10 release; basically no change for Intel drivers; and just a handful of OpenGL 4.5 extensions for AMD.
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.
Learn about the OpenGL and OpenCL versions that are supported by your computer in OS X Mavericks and OS X Yosemite. The lowest version of OpenGL is now 3.3, with all 2011 and later desktop and laptops running OpenGL 4.1. OpenCL on desktops and laptops since 2012 are running OpenCL 1.2, with earlier version running 1.0.
Tristan Lorach explains how to use the NV_command_list OpenGL extension to get maximum rendering performance from your GPU with close-to-zero CPU overhead while rendering. The command list approach combines bindless extensions, tokenized rendering, state objects, and flexible command listing. The accompanying YouTube video demonstrates interactive rendering of extremely complex models.
An excellent first part article/tutorial of a series on ‘Ray tracing with OpenGL Compute Shaders’ by Kai Burjack. Its pretty rare to find good tutorials covering such topics especially using modern OpenGL techniques.
OpenGL and The Khronos Group would like to thank Richard S Wright for his gracious donation to OpenGL.org of his @OpenGL account. If any of you are into astronomy, be sure to follow Richard on his @AccidentalAstro account. For those that are not aware, Richard is a co-author of the OpenGL Superbible.
NeoAxis Group Ltd is glad to announce that the universal OpenGL-based 3D development framework NeoAxis 3D Engine is now completely free, as the community has been asking for it. You can freely download the recently published SDK 3.0, which includes all the features previously reserved to Unlimited and Source licences. From now, the engine will be developed as free tool. Paid licenses will still give customers access to a bigger part of the engine’s source code.
