Khronos Releases OpenXR 0.90 Provisional SpecificationThe Khronos® Group, an open consortium of leading hardware and software companies creating advanced acceleration standards, announces the ratification and public release of the OpenXR™ 0.90 provisional specification. OpenXR is a unifying, royalty-free, open standard that provides high-performance access to augmented reality (AR) and virtual reality (VR)— collectively known as XR—platforms and devices. The new specification can be found on the Khronos website and is released in provisional form to enable developers and implementers to provide feedback at the OpenXR forum.

Tobii announced at the 2019 Game Developers Conference, a new software development kit (SDK) for XR applications and new resources for PC developers. The new developer guides and tools ease eye tracking integration in a variety of important ways, from providing new libraries and APIs for intuitive object mapping and selection, to delivering example code and implementation tutorials. The Tobii XR SDK and associated libraries are designed to be used with and complement the capabilities of device-specific SDKs associated with VR headsets that support eye tracking and the OpenXR initiative.

Radeon GPU Analyzer (RGA) is thte AMD offline compiler and integrated code analysis tool, supporting the high-level shading and kernel languages that are consumed by DirectX 11, Vulkan, OpenGL and OpenCL, including HLSL, GLSL, the OpenCL kernel language, and SPIR-V. Along with support for Vulkan in the RGA GUI, the biggest new feature in RGA 2.1 is a new analysis system that lets you obtain the GCN machine ISA and hardware resource information, using the compiler in the running driver that you have in your system. Learn more on the Radeon GPU Blog from AMD.

NVIDIA VKRay is a set of three extensions that bring ray tracing functionality to the Vulkan. VK_NV_ray_tracing is the stable registered extension for adding ray tracing effects to Vulkan raster applications. Callable shaders provide applications with the means to reuse shading code across many different objects. The new stable extension includes API updates for cleaner code and flexible memory management. Learn more in the NVIDIA Developers News center.

Google announces Stadia, a game streaming service using VulkanAt its GDC 2019 keynote, Google announced Stadia, a cloud streaming service allowing graphically-intensive games to be available to anyone who can run Chrome. Doom Eternal will be one of the first games on the platform, streaming at 4K resolution, 60 fps. Google has partnered with AMD to design a custom GPU with "more than ten teraflops of power," which is paired with a custom CPU for each Stadia rendering instance. Those instances will run on Linux and use the Vulkan API. Google has partnered with Unreal and Unity to "bring full support to the most popular and familiar game engines to our development community."

Out of GTC and into GDC, NVIDIA will talk about Q2VKPT, the Vulkan-based renderer for Quake 2 that uses hardware accelerated path tracing and advanced spatiotemporal denoising. One of the speakers is former NVIDIA intern Christoph Schied, a Ph.D. student at the Karlsruhe Institute of Technology in Germany, creator of Q2VKPT. For a sneak peak checkout this article with Video and Screenshots.

Khronos will be holding their Annual GDC Developer Day Sessions on March 19th in Moscone West Room 2020. The complete schedule is available online:

  • glTF and WebGL - 10:00am – 11:00am
  • OpenXR – State of the Union – 11:20am – 12:20pm
  • Vulkan – State of the Union - 1:20pm – 2:20pm
  • Making Use of New Vulkan Features – 2:40pm – 3:40pm
  • Bringing Fortnite to Mobile with Vulkan and OpenGL ES – 4:00pm – 5:00pm
  • Ubisoft's Experience Developing with Vulkan – 5:30pm – 6:30pm
Running all day March 18-19 will be the Khronos OpenXR Table at VRDC. Finally on March 20th starting at 6:30pm, there will be the annual WebGL/WebVR Meetup to be held in Galvanize. In past years there were over 200 people attending with only standing room and people being turned away. If you want to get in, show up early. This event will be live streamed on the Silicon Valley WebGL group on Facebook.

NeoAxis Group announces a new 3D development environment NeoAxis Engine version 2019.1. The environment can be used to develop all kinds of 3D projects such as computer games, visual trainers, VR systems, to visualize processes and develop windowed applications. The engine uses OpenGL API for rendering.

Airbus Defence and Space and Core Avionics & Industrial Inc. announced today, at Aerospace TechWeek in Munich, a technology partnership to enable the use of GPU compute in airborne systems and applications that require the highest RTCA DO-178C/EUROCAE ED-12C DAL A safety certifications. Based on the use of CoreAVI’s platforms for safety certifiable applications, including its VkCore™ SC Vulkan®-based compute driver architecture, the two companies will work together to fully define and be ready to deliver software and systems that perform safety critical GPU compute operations to enable the most advanced autonomous systems and other avionics applications that can take advantage of GPU compute functions. CoreAVI chairs Khronos’ Vulkan SC Working Group and is driving forward new standards to support true GPU compute capabilities using graphics processors.

Khronos’ OpenCL, SYCL, and SPIR-V Standards Find Growing Synergy with LLVM’s Compiler CommunityThe Khronos OpenCL working group recently created a new Tooling Subgroup with the aim of improving the tools ecosystem for this widely-used open standard for heterogeneous computation—in particular, boosting the development of tooling components that can be shared by multiple vendors. Subgroup members have been meeting regularly to coordinate the overall direction for OpenCL tools, with an emphasis on strengthening the development of tools in open source, particularly by encouraging collaboration between the OpenCL and LLVM communities.

LunarG donates the Vulkan SDK to Khronos to promote a unified Vulkan ecosystem and enable wider collaboration on SDK developmentLunarG is strengthening its collaboration with Khronos by opening its desktop SDK build and packaging scripts to the Vulkan Working Group. This will enable collaboration between all Vulkan Working Group members to support and evolve a unified Vulkan SDK that can serve the needs of the industry, while avoiding fragmentation in the Vulkan ecosystem. LunarG will continue to play a central role in developing and supporting the desktop Vulkan SDK, and will continue to host and maintain the Vulkan SDK download site, now with the additional support and resources of Vulkan Working Group Members.

Neil Trevett, president of the Khronos Group will be chairing a discussion group at Operational Safe Systems for Level 5 Automation (OSS5) on February 28th in San Francisco. Discussions will explore if existing open standards a reasonable starting point for safety critical APIs. The newly formed Vulkan SC Working Group makes a compelling starting point for safety certifiable access to GPU acceleration for graphics and compute.

At its MWC keynote in Barcelona today, Microsoft promised to keep the HoloLens ecosystem open. “We believe in an open API surface area and driver model. We will continue to participate in guiding open standards like OpenXR so anyone can innovate with our headset from the sensors that are being used to the differentiated experiences that are being created,” Microsoft’s HoloLens chief Alex Kipman said today. HoloLens 2 supports an open API surface and driver model—and Microsoft continues to support open standards such as Khronos and OpenXR. Learn more about OpenXR and the companies behind it.
