Press Release: Vulkan SDK, Tools and Drivers are Ray Tracing Ready

Khronos announces that LunarG has released the Vulkan Software Development Kit (SDK) version, 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.

Blog: Holochip Develops Breakthrough Light Field Rendering Using Vulkan Ray Tracing

For the past two years, Holochip has been working on light field technology for the US Navy’s Aegis program. The program calls for a table top light field display that can accommodate horizontal and vertical real-time parallax. In October 2020, the team working on OpenXR™ at Holochip released an open source Vulkan® example projectand started work with light field display technology using the OpenXR API. As a result of both efforts, Holochip has discovered a method of light field real-time rendering that is built upon the Khronos Group’s Vulkan Ray Tracing extensions.

Catching up after the Khronos 3D Commerce Working Group Webinar - Q&A

Recently, the Khronos 3D Commerce Working Group hosted a webinar to discuss its activities, including why industry alignment on the glTF file format (the “JPEG for 3D”) is crucial, and how standardization will bring new opportunities to any designer, retailer, manufacturer or technology company developing 3D experiences. The panel was led and moderated by Leonard Daly, President of Daly Realism, who was joined by industry experts from Wayfair, UX3D, Amazon Imaging Services, Autodesk, DGG, DreamView, Microsoft and Shopify. At the end of the webinar, the audience submitted questions for the panelists. The answers as a Q&A are now available online.

glTF Validator and glTF Tools for VSCode updated for new PBR Extensions

Lots of exciting glTF news today! Khronos announced three new new Physically Based Rendering extensions for Clear Coat, Transmission and Sheen which continues to build a powerful, interoperable, material model for the glTF ecosystem. As well, new versions of glTF Validator (2.0.0-dev.3.3) and glTF Tools for VSCode (2.3.2) were also published today, adding support for all three of the PBR extensions.

Khronos Releases Wave of New glTF PBR 3D Material Capabilities

Today, The Khronos Group 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 (KHR_materials_clearcoat extension), Transmission (KHR_materials_transmission extension) and Sheen (KHR_materials_sheen extension) 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.

AMD announces new Vulkan ray tracing extension support in latest driver

AMD has announced after a brief spell in their beta driver, support for the following new Vulkan ray tracing extensions are now available in their main Radeon Adrenalin driver 20.11.3 and onwards: VK_KHR_acceleration_structure, VK_KHR_ray_tracing_pipeline, VK_KHR_ray_query, VK_KHR_deferred_host_operations, and VK_KHR_pipeline_library. In addition to the ray tracing extensions, there’s also now support for VK_KHR_shader_terminate_invocation.

RapidCompact: The 2020 challenge and its current state - Scaling Up 3D Processes

RapidCompact has a three part blog looking at the benefits of e-commerce and the importance of an efficient delivery format. In this part, RapidCompact looks at streamlined 3D workflows and addresses the challenges represented by variety of interfaces, manual workload, and lack of consistency. RapidCompact, an active member in Khronos’ 3D Commerce WG, addresses these needs through active collaboration in the industry to align the ecosystem, enable sustainable innovation, and ease consistency through standardization.

An Open Future: Sidequest joins the Khronos Group to support OpenXR

​The Khronos Group would like to Welcome Sidequest as an Associate member. At SideQuest we believe that XR deserves an open future to be able to properly flourish, and we at SideQuest are delighted to be able to support that future. OpenXR is the working group we are particularly interested and we plan on showing our support by helping our partners, developers and users to see the benefits that OpenXR provides.

Raspberry Pi Vulkan Update

Raspberry Pi has announced that their V3DV Vulkan Mesa driver for Raspberry Pi 4 has demonstrated Vulkan 1.0 conformance. The conformance process is a way to ensure that Khronos standards are consistently implemented by multiple vendors, so as to create a reliable platform for application developers.
