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.
In early August the Khronos team was at SIGGRAPH in Los Angeles, where we celebrated OpenGL’s 25th anniversary at the BOF Blitz Party. We also announced a new website, as well as OpenGL 4.6, a growing glTF ecosystem, and the Vulkan Portability Initiative. Learn more about BOF Blitz.
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.
Looking for complete set of C++11 classes to wrap OpenGL 4.6 that relies on modern Direct State Access (DSA) usage? Try Ali Can Demiralp’s wrapper on github.com based on GLEW 2.1. Also supports CUDA interoperation and GLM for OpenGL Mathematics.
If you decide to install Google Earth today, you will be interacting with the Pro version. 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.

OpenGL 4.6 adds support for SPIR-V extensions (GL_ARB_spirv_extensions) so you can tell what OpenGL extensions have corresponding SPIR-V support. The GPU Caps Viewer has been updated to report the SPIR-V extensions of OpenGL 4.6 drivers.
Excited about NVIDIA’s latest driver with OpenGL 4.6 support? But you missed getting the details at SIGGRAPH 2017? Watch Jeff Kiel and Mark Kilgard explain OpenGL 4.6, a live demo of Nsight analyzing GFXBench’s OpenGL path, multi-vendor interop, NVIDIA’s open source contributions for graphics, and more. Alternatively flip through theslides.
The Khronos BOFs at SIGGRAPH will all be livestreamed today. Here is the embedded version:
The Khronos Group announces from the SIGGRAPH 2017 Conference the immediate public availability of the OpenGL 4.6 specification. OpenGL 4.6 integrates the functionality of numerous ARB and EXT extensions created by Khronos members AMD, Intel, and NVIDIA into core, including the capability to ingest SPIR-V shaders. Learn more about this release. Khronos encourages and welcomes all feedback on the new specification.
To coincide with the release of OpenGL 4.6, NVIDIA is pleased to announce the immediate availability of our OpenGL 4.6 beta drivers for Windows and Linux. These drivers provide full OpenGL 4.6 and GLSL 4.60 functionality and also add support for the GL_KHR_parallel_shader_compile extension released today. This beta release is based on the published OpenGL 4.6 Khronos Specification, and is expected to pass the OpenGL 4.6 Khronos Conformance Testing Process when available. Current conformance status can be found online. Further details and driver downloads are available at the NVIDIA OpenGL driver website.
The Khronos Group has updated the Birds of a Feather schedule and speaker list. If you will be at #SIGGRAPH2017 be sure to visit the BOF Blitz and After Party! BOFs include: OpenVX, NNEF, OpenCL and SYCL; COLLADA; glTF; WebGL; OpenXR; and Vulkan, OpenGL & OpenGL ES to wrap up the day. glTF has just posted their list of speakers, and what a line they have for you in store for you. At the end of the day, be sure to hang around for the BOF Blitz After-Party. The BOFs will be live streamed with video available afterwards, and t-shirts available online, for all those folks not attending.
The entire WebGL Insights book is now available for free in PDF format with permission from CRC Press. The 23 chapters on advanced WebGL topics from 42 authors and 25 reviewers is basically still the only book on _advanced_ WebGL. Get your copy today, and start making awesome WebGL content.
Researchers at CMU and NVIDIA have developed an open source shading language and compiler framework named Spire enhanced to support shader components for high-performance rendering. The Spire compiler can generate either GLSL or SPIR-V output for use with OpenGL and Vulkan based engines. The work interfaces with a modernmini 3D engine that supports equivalent back-ends for both OpenGL and Vulkan. The researchers will present this year’s work at SIGGRAPH next week which builds on a paper from last year’s SIGGRAPH.
