Raspbian is the official Linux distribution of the Raspberry Pi products, and a new version has been released by its developers. The important change that was announced for the developers is the introduction of a new and experimental OpenGL driver for the desktop which uses the GPU to provide hardware acceleration. Since it’s not exactly stable, it’s disabled by default. It can be activated from raspi-config, under Advanced Options->GL Driver. Also, it will only work for Raspberry Pi 2 and not of the other versions.
Google engineers have open-sourced a new suite of libraries and tools on Github relating to OpenGL called ION. ION is described as “a portable suite of libraries and tools for building client applications, especially graphical ones. It is small, fast, and robust, and is cross-platform across many platforms and devices, including desktops, mobile devices, browsers, and other embedded platforms.”
The 48th 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 integrate the Ant Tweak Bar library in an OpenGL application in order to create a user interface.
Learn about Vulkan, the new graphics and compute API directly from Khronos, the people who are creating it. In this 1-hour session, we will talk about the API, and go into details about the Vulkan SDK from LunarG, and much more. Register today!
NVIDIA just posted the next installment of their Vulkan tips blog series. This episode talks about memory management. Vulkan offers another key difference to OpenGL with respect to memory allocation. When it comes to managing memory allocations as well as assigning it to individual resources, the OpenGL driver does most of the work for the developer. This allows applications to be developed, tested and deployed very quickly. In Vulkan however, the programmer takes responsibility meaning that many operations that OpenGL orchestrates heuristically can be orchestrated based on an absolute knowledge of the resource lifecycle.
Amazon is now accepting pre-orders on the new Vulkan Programming Guide: The Official Guide to Learning Vulkan. The Vulkan Programming Guide is the essential, authoritative reference to this new standard, for graphics programmers at all levels of experience, in any Vulkan environment, on any platform. The book is written by John Kessenich and Graham Sellers, both Khronos Group members.
This post by Peter Messmer on the NVIDIA Parallel Forall blog provides the basic steps to create a (full) OpenGL context using EGL in a headless environment, with code examples. EGL context creation is particularly relevant for accelerated rendering on HPC systems or in a cloud environment, where context management via X11 is often times impractical. Applications include in situ visualization and CUDA/OpenGL interoperation.
The upcoming Qt 5.6.0 release includes the Qt Charts 2.1.0 add-on. This Qt Charts release contains new features and bug fixes based on customer requests. The biggest visible improvement done to Qt Charts 2.1.0 is a performance related change. For line and scatter series we’ve added support of accelerated drawing with OpenGL. The change radically improves performance in cases involving large data sets. We’ve added the OpenGL Accelerated Series Example to show how you can enable OpenGL acceleration for QLineSeries and QScatterSeries.
Nvidia announced the release of a new Beta version of its graphics drivers for GNU/Linux, FreeBSD and Solaris operating systems, version 361.16. According to the release notes, the Nvidia 361.16 Beta video driver includes the brand new OpenGL Vendor-Neutral Driver infrastructure, also known as GLVND, which is supported by the Nvidia OpenGL and GLX drivers.
GL_ARB_tessellation_shader support for Ivy Bridge and Haswell is now complete. This latest Intel OpenGL 4.0 work will be found in the next Mesa release due out around March.
