Vulkan, WebGL & glTF sessions today!

Mar 16, 2016

The Khronos Group is holding a series of sessions today in San Francisco. If your are at GDC, take a break and a 5 minute walk over to Green Space to see one of the several sessions Khronos will be hosting. Start the day off with Jon Peddie Research at 8:30AM PT. After a short break there will be 3 back-to-back sessions: WebGL+glTF at noon, Khronos Chapters lunch at 1PM and Vulkan at 2PM. Ending the day off will be a large Khronos Social from 7PM-9:30PM. All the details you need are on the Khronos event page. Unable to attend? No worries, Khronos has you covered with a Livestream of both the WebGL + glTF session and the Vulkan session. We’re expecting a lot of people today and space is limited. Please be sure to register for one of the few remaining spots if you haven’t done so already.

Khronos Group Sessions during GDC 2016 week

Mar 14, 2016

The Khronos Group is hosting a series of sessions on Wednesday March 16th near the Moscone at Green Space in San Francisco. Sessions will cover WebGL, glTF, Khronos Chapters and Vulkan. A Khronos Social on Wednesday evening will give developers a chance to meet and chat with Khronos members. Starting off the day is the JPR Press Briefing on the Gaming Market. Details and registration for the Khronos sessions are available online. For those that cannot attend in person, there will be live streaming of the sessions, and videos available a few days afterwards. For those at GDC all week, you will find a list of companies exhibiting Khronos technology on our GDC week event page.

New OpenGL 4 + Virtual Reality Example Code

Mar 14, 2016

A new, modern OpenGL tutorial for both windowed and VR rendering released, showing in about 400 lines of C++ how to use all of OpenGL’s major features: - Window, OpenGL, HMD, and OpenGL extension initialization - Triangle mesh rendering (OpenGL Vertex Array Buffers) - Shader loading, compilation, and argument passing (OpenGL Program, Shader, and Uniform Buffer Objects) - Offscreen rendering (OpenGL Framebuffer Objects) - Materials and image file loading (OpenGL Texture and Sampler Objects) - GPU ray tracing (including ray setup compatible with rasterization) - Procedural texturing - A tiny vector math library - Basic keyboard and mouse handling for a free-flying camera - Virtual reality tracking and rendering (OpenVR)

Open source high performance canvas drawing API for OpenGL released

Mar 02, 2016

Fast UI Draw, source code available on github, has now been open sourced. Fast UI Draw is a high performance Canvas renderer that is tuned for Intel GPU’s (but can work for other GPU’s) that under significant load is much faster than many other Canvas renderers. Fast UI Draw when running has very few GPU states, very few draw calls even under very complicated scenes. In addition, Fast UI Draw has a unique methodology to handle clipping that allows for applications to have rotations, projection, and clipping without incurring significant CPU load from setting, saving or restoring clipping. Fast UI Draw is available under the MPLv2 and a very alive project undergoing active development.

Vulkan is forged - Specification 1.0 is released

Feb 16, 2016

The Khronos Group announces the immediate availability of the Vulkan 1.0 royalty-free, open standard API specification. Vulkan provides high-efficiency, cross-platform access to graphics and compute on modern GPUs used in a wide variety of devices from PCs and consoles to mobile phones and embedded platforms. This ground-up design, complementing the OpenGL and OpenGL ES 3D APIs, provides applications direct control over GPU acceleration for maximized performance and predictability with minimized CPU overhead and efficient multi-threaded performance. Multiple Vulkan 1.0 hardware drivers and SDKs are available immediately for developers to begin creating Vulkan applications and engines.

NeoAxis 3D Engine 3.4 Released

Feb 14, 2016

NeoAxis Group Ltd has released a new version of the free OpenGL-based universal environment for 3D project development NeoAxis 3D Engine 3.4. This release does not include the big amount of changes since the main work is focused on version 4. This release features updated tools skins, improved physics, new exporters for the latest Autodesk 3ds Max and Maya, improved Apple OS X support and updated demo maps.

Raspbian Gets Experimental OpenGL Driver, GPU Now Used for Acceleration

Feb 11, 2016

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 Releases ION OpenGL Open-Source Library

Feb 10, 2016

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.”

User Interface with Ant Tweak Bar Library Published

Feb 08, 2016

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 directly from Khronos in a one hour webinar

Feb 08, 2016

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: Vulkan Memory Management

Feb 05, 2016

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.

Vulkan Programming Guide: The Official Guide to Learning Vulkan

Feb 05, 2016

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.

EGL Eye: OpenGL Visualization without an X Server

Jan 24, 2016

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.

Qt Charts 2.1.0 Release with OpenGL improved performance

Jan 22, 2016

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.
