Khronos Releases New NNEF Convertors, Extensions, and Model Zoo

The Khronos Group announces a significant expansion in the ecosystem for the NNEF (Neural Network Exchange Format) open, royalty-free standard that enables hardware manufacturers to reliably exchange trained neural networks between training frameworks and inference engines. New and improved NNEF open source convertors, including for TensorFlow Lite and ONNX, enables NNEF to be used to carry trained frameworks from a wider range of training frameworks. A set of extensions to the NNEF 1.0 specification enables NNEF files to contain richer networks of operations and topologies. Finally, an openly available NNEF Model Zoo enables inferencing engines to test their reliable import of NNEF models. More information on NNEF can be found at the Home Page.

Another blog explaining Vulkan synchronization has just been posted by @Themaister. Synchronization in Vulkan is a large hurdle to overcome when learning the API, and rather than mechanically explaining how it works, the goal in this blog is to instil a mental model in the reader. Despite its reputation for maddening complexity, it is actually understandable and quite logical once you get over the initial hurdles.

Khronos Group SIGGRAPH Sessions - slides and video now online

​The Khronos Group had several session on BOF Day at SIGGRAPH 2019. Most of the slides and video are now online:

Be sure to visit the event page for a detailed list of links to all the presentations and videos.

Vulkan 1.1.119 was released right after 1.1.118. In total, three new extensions have been added: VK_AMD_shader_core_properties2, VK_AMD_pipeline_compiler_control and VK_KHR_pipeline_executable_properties. The first two are AMD vendor extensions, while the most recent extension was worked on jointly by engineers from Intel, Valve, Google, NVIDIA, AMD, Arm, and Samsung. See the Change log on GitHub for additional the details.

As part of its unwavering commitment to open source and open standards, Collabora is proud to be part of bringing the recently-released OpenXR 1.0 to life. We are pioneering the Monado open source runtime for OpenXR to ensure the future of XR is truly open and accessible to all hardware vendors. With the release of OpenXR 1.0, we were able to publish the few changes required to adapt Monado to the 1.0 API, which will be our target ABI from here on. Learn more about Monado and Collabora’s work on OpenXR.

The Khronos Group BOF day is today, July 31. For those folks that really wanted to catch some of the BOF Day sessions, but couldn’t make, we have it covered for you. Starting at 9AM PT, the morning livestream will start on YouTube. The afternoon sessions will be on a second afternoon livestream also on YouTube. Learn more about the Khronos Group BOF Day and all of the various sessions on our SIGGRAPH 2019 event page.

Khronos Releases OpenXR 1.0 Specification

The Khronos Group announces the ratification and public release of the OpenXR 1.0 specification together with publicly available implementations and substantial ecosystem momentum. OpenXR is a unifying, royalty-free, open standard that provides high-performance, cross-platform access to virtual reality (VR) and augmented reality (AR)— collectively known as XR—platforms and devices. The new specification can be found on the Khronos website and via GitHub. To learn more about the OpenXR 1.0 Specification and other Khronos activity at SIGGRAPH, read the Press Release.

The Khronos Group announces new 3D Commerce Working Group and key updates to flagship standards WebGL, glTF, and Vulkan. In the spirit of continued commitment to the SIGGRAPH community of interactive graphics professionals, Khronos delivers a number of developments and initiatives, including:

  • 3D Commerce Initiative Becomes Khronos Working Group; Call for Participation Announced
  • WebGL Releases High-Impact Extensions and Ecosystem Developments
  • glTF Universal Texture Extension Drafting Underway Using Binomial’s Basis Universal Texture Technology; First Prototype Support Appears in Engines
  • glTF Tools Ecosystem Expands, Including Universal Texture Tools and glTF Import/Export in Blender 2.80
  • New Vulkan Extensions Ship; Vulkan Sees Increased Usage by CAD and Professional Authoring Tools

Khronos BOF Day at SIGGRAPH 2019–Next Week!

SIGGRAPH is next week! The conference is July 28-August 1. For those going, Khronos will be hosting several Birds of a Feather sessions. For all those folks that will not be present, we will be offering live streaming of all our sessions (glTF, WebGL, OpenXR and Vulkan) on the Khronos Group YouTube Channel, and will follow up with recorded video the following week. For complete details on all the sessions, please ask your friends and co-workers to take a look at our SIGGRAPH event page! A special thanks to our Title sponsor NVIDIA, Beer Sponsor LunarG, and Demo sponsor Cesium, for making possible the Khronos Networking Reception at the end of the day.

Join Khronos for their Inaugural 3D Commerce BOF at SIGGRAPH!

The Khronos Group is excited to officially kick off their first 3D Commerce Birds of a Feather (BOF), where they will discuss their efforts to align the retail industry’s 3D assets and specifications to optimize workflows and minimize distribution costs in the retail sector. The BOF will provide insight into the goals and directions of the 3D Commerce group so that interested parties can judge if they want to get involved. Join and help Khronos lead a disruptive change in terms of product digitalization and pushing e-commerce to the next level!
