Neil Trevett, President of The Khronos Group, talks to Architosh in this two-part series about OpenGL and the future of graphics standards. On the eve of SIGGRAPH 2017 Neil Trevett spoke to Architosh about the evolving OpenGL standard as well as directions the group is taking to plot a path for a universal graphics API that engages the use of low-level APIs. Read more about why OpenGL isn't packing for retirement just yet a the key thing in OpenGL 4.6 is SPIR-V is part of core.
Initial Vulkan SDL support allows the Simple DirectMedia Library commonly used by games to manage Vulkan surface creation across Android / Linux / Windows in a uniform manner. These are convenient Vulkan helpers for those using SDL and will not make your existing SDL OpenGL application suddenly support Vulkan. This initial Vulkan SDL support was done by Jacob Lifshay and Khronos member Mark Callow. (Source: Phoronix)
Virtual Reality is becoming increasingly commercially viable, just as augmented reality is also gaining popularity. But as with any gold rush, developers and vendors are feverishly working to stake their claim on a new frontier while still partially mining in the dark, as both VR and AR still have a long way to go before reaching maturity. Now is the time to standardize VR functionality which will help decrease porting costs for developers, reduce uncertainty for consumers and create the core VR/AR platform standards that can be expanded over time. Read the VentureBeat article and learn how OpenXR fits into all this.
The open source C++11/C++14 and OpenGL graphics engine Magnum recently added first-class WebAssembly support. An article on the official blog explains how to easily compile your C++ projects to WebAssembly, compares it to asm.js and mentions a few useful tips for best online experience. Last but not least, there's a bunch of online demos that use both WebGL 1 and 2, showing how a single codebase can be run both natively and in the browser.
Mazatech released version 4.5 of AmanithVG SDK on GitHub (http://github.com/Mazatech/amanithvg-sdk), a C/C++ library that implements OpenVG 1.1 specifications from Khronos Group. AmanithVG SDK is features-unlimited and it is free for evaluation purposes. It supports desktop, mobile and embedded platforms: Windows (x86, x86_64), Mac OSX (ub), Linux (arm, arm-v6hf, arm-v7a, aarch64, mipsel, mips64el, pppc64el, x86, x86_64), Android (arm, arm-v7a, arm64-v8a, mips, mips64, x86, x86_64), iOS (ub), QNX (armv7-le, x86). The package also includes a set of ten tutorials covering different OpenVG features: gradients paint types, patterns, stroking, alpha blending, images, masking and text, completed with source code and detailed description on the AmanithVG website. The building system is based on CMake, so all the tutorials support Visual Studio, XCode, Android Studio as well as plain Makefile.
Sundog Software released version 5.0 of the SilverLining Sky, 3D Cloud, and Weather SDK, featuring support for OpenGL 2.0 through 4.5. SilverLining is a C++ library that simulates real-time skies for any given time, location, and weather conditions. It implements a variety of volumetric rendering techniques to represent many different 3D cloud types in a physically realistic manner from any angle, while maintaining high frame-rates. SilverLining 5 introduces new hand-modeled storm clouds suitable for use in flight simulators. Large, natural-looking cumulonimbus thunderheads and towering cumulus clouds in various stages of development are included. SilverLining integrates into any OpenGL application easily with simple calls to initialize, update, and draw its skies, clouds, and precipitation effects. Integration code for OpenSceneGraph is included. SilverLining is widely used in the training and simulation industry, and powers the popular "SkyMaxx Pro" add-on for the X-Plane flight simulator.
Visualization is a great tool for understanding large amounts of data, but transferring the data from an HPC system or from the cloud to a local workstation for analysis can be a painful experience. Analyzing and visualizing data right where it is generated and using server-side rendering lets you deliver high quality visual content to any client hardware. Whether it’s a DGX station or a smartphone. With the arrival of EGL, taking advantage of OpenGL on a headless server has become even simpler, making it unnecessary to run an X server or any other tools. Slight modifications to your OpenGL context management code using EGL functions is required as described in this post. Using EGL also requires you to link your application to different libraries. This post from NVIDIA is about how to correctly link a modern OpenGL application.
Google has merged Earth Pro with the free Google Earth, now offering only Goole Earth Pro. Another notable change: In the past you had the option to switch between DirectX or OpenGL when running Google Earth on Windows, now the application defaults to OpenGL mode. Learn about the other improvements.
Codeplay announces SPIR-V support for ComputeCpp in v0.3.0. This beta implementation of SPIR-V for OpenCL support means that developers can use SYCL and ComputeCpp to develop for any OpenCL hardware that includes a driver that consumes SPIR-V.
