The Khronos® Group announces the public release of the latest set of Physically Based Rendering (PBR) material extensions for the Khronos glTF™ 3D asset format. The new extensions enable material properties such as refraction, color attenuation, and volumetric properties to be used by diverse renderers from real-time rasterization to production-class path-tracing. glTF is a flexible, royalty-free asset format from Khronos designed for efficient run-time transmission and loading of 3D scenes and models on a wide variety of platforms including web browsers, mobile devices, PC desktops and the cloud. Leading rendering engines such as Babylon.js, Google’s Filament, and three.js already support some or all of the new PBR extensions, together with applications including Adobe’s Substance 3D Stager, Dassault Systèmes 3DEXPERIENCE Platform, DGG RapidCompact and UX3D’s Gestaltor.
The Khronos Group announces the release of the 3D Commerce Viewer Certification program. Viewer Certification clears the way for 3D and AR-powered shopping and the proliferation of digital goods by ensuring that 3D assets look the same across the metaverse.
The Khronos Group announces the ratification of KTX 2.0, adding support for Basis Universal supercompression to this container format for reliable, ubiquitous distribution of GPU textures. Basis Universal is a compression technology developed by Binomial that produces compact textures that can be efficiently transcoded to a variety of GPU compressed texture formats at run-time. Additionally, Khronos has released the KHR_texture_basisu extension enabling glTF to contain KTX 2.0 textures, resulting in universally distributable glTF assets that reduce download size and use natively supported texture formats to reduce GPU memory size and boost rendering speed on diverse devices and platforms. Lastly, Khronos has released open source tools and transcoders, together with developer and artist guidelines, to enable and encourage widespread usage of KTX 2.0 textures throughout the glTF ecosystem, including the three.js, Babylon.js and Gestaltor viewers that have already integrated support.
Today, The Khronos® Group, an open consortium creating graphics and compute interoperability standards, and the European Machine Vision Association (EMVA), the leading European industry association dedicated to vision technology, jointly announce the formation of an Embedded Camera API Exploratory Group, open to all at no cost, to explore industry interest in the creation of open royalty-free API standards for controlling embedded cameras and sensors. All participants will be able to discuss use cases and requirements for new interoperability standards to accelerate market growth and reduce development costs in embedded markets using vision and sensor processing and associated acceleration. If the Exploratory Group reaches significant consensus then Khronos and EMVA will work to initiate the proposed standardization projects at the appropriate organizations.
The Khronos Group announces the ratification and public release of the SYCL 2020 final specification—the open standard for single source C++ parallel programming.

Based on C++17, SYCL 2020 enables easier acceleration of standard C++ applications and drives a closer alignment with the ISO C++ roadmap.
Today, The Khronos Group announces that LunarG has released the Vulkan Software Development Kit (SDK) version 18.104.22.168, with full support for the new Vulkan Ray Tracing extensions, including Validation Layers and integration of upgraded GLSL, HLSL and SPIR-V shader tool chains. The Khronos open source Vulkan Samples and Vulkan Guide have been upgraded to illustrate ray tracing techniques. Finally, with production drivers shipping from both AMD and NVIDIA, developers are now enabled to easily integrate Vulkan Ray Tracing into their applications.
Today, The Khronos Group, an open consortium of industry-leading companies creating advanced interoperability standards, announces the release of a set of new Physically Based Rendering (PBR) material extensions for glTF. glTF is Khronos’ royalty-free format for widespread, efficient transmission and loading of 3D scenes and models, known in the industry as the ‘JPEG of 3D’. PBR enables developers and artists to achieve photorealism through rendering parameters that correspond to real-world physical properties of materials in 3D assets. These new extensions for Clear Coat, Transmission and Sheen build on the existing PBR capabilities of glTF 2.0, and together with additional upcoming extensions, are creating a powerful, interoperable, physically-based material model for the glTF ecosystem.
Beaverton, OR – July 28, 2020 – Today, The Khronos® Group, an open consortium of industry-leading companies creating graphics and compute interoperability standards, announces multiple conformant implementations of OpenXR™ are shipping from Oculus and Microsoft, leveraging the newly opened OpenXR 1.0 Adopters Program and open source conformance tests. OpenXR is a royalty-free, open standard that provides direct access into Augmented Reality (AR) and Virtual Reality (VR)—collectively known as XR—runtimes across diverse platforms and devices. The OpenXR Adopter’s Program enables consistent cross-vendor testing and reliable operation of OpenXR across multiple platforms and devices with OpenXR-conformant products published on the Khronos Conformant Product Registry.
The Khronos Group announces the ratification and public release of the SYCL 2020 Provisional Specification.
