The Khronos Group releases the Vulkan Ray Tracing Final Specification

Today, Khronos has released the final versions of the set of Vulkan, GLSL and SPIR-V extension specifications that seamlessly integrate ray tracing into the existing Vulkan framework. This is a significant milestone as it is the industry’s first open, cross-vendor, cross-platform standard for ray tracing acceleration - and can be deployed either using existing GPU compute or dedicated ray tracing cores. Vulkan Ray Tracing will be familiar to anyone who has used DirectX Raytracing (DXR) in DirectX 12, but also introduces advanced functionality such as the ability to load balance ray tracing setup operations onto the host CPU. Although ray tracing will be first deployed on desktop systems, these Vulkan extensions have been designed to enable and encourage ray tracing to also be deployed on mobile. Additionally, Khronos has posted a blog on “Vulkan Ray Tracing Best Practices for Hybrid Rendering” which explores ray tracing techniques in Wolfenstein: Youngblood.

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.

3D Commerce Working Group tasked with bringing clarity to disruptive technology

The newly formed 3D Commerce Working Group is tasked with exploring the opportunity to accelerate the adoption of 3D experiences by establishing a set of universal standards for platform-agnostic 3D model creation and distribution.

Shrenik Sadalgi, Director of the Next R&D Group at Wayfair and Chair of the 3D Commerce Working Group, believes the industry needs standards and guidelines so that 3D content can be experienced consistently across a variety of platforms and on a variety of devices. Other challenges that standardization can help address include optimizing industry workflows to minimize cost, and bringing down barriers to entry for retailers and technologists. “Bringing this kind of radical change across the retail industry will require collaboration between many different retail and technology companies.”

OpenXR and an Introduction to the Khronos Group

The Khronos Group is a consortium of over 150 hardware and software companies who help define standards for various compute, graphics, and media APIs (e.g. if you’ve worked with computer graphics, then you’ve probably already come across one of their more familiar specifications), but the work of the Khronos Group goes well beyond graphics to include OpenXR, OpenCL, and several other active standards.

Creating open standards and specifications (i.e., cross-platform APIs) requires a breadth of knowledge to ensure they provide a rich set of functionality while allowing for future innovations. Thus, the importance of having a consortium with such a large number of members cannot be understated.

OpenMP 5.1 Released With Better Interoperability For CUDA / AMD HIP / OpenCL

It’s been two years already since the release of the OpenMP 5.0 specification and the update released on Friday is quite a worthy update:

OpenMP 5.1 introduces a new interop construct for improving interoperability with non-OpenMP device execution contexts. This aims to improve the portability of OpenMP 5.1+ to non-native interfaces/accelerators. This interop construct is designed with NVIDIA CUDA, AMD ROCm/HIP, and OpenCL in mind. The interop construct is used for dealing with interoperability properties for one or more “foreign runtime environments”.

Faster Load Times with glTF’s GLB Format

The PlayCanvas team announced the Editor support of glTF GLB conversion with model and animation imports. This gives developers an order of magnitude reduction in load times compared to the JSON format while keeping similar gzipped download size. Using the Stanford Dragon model (2,613,679 vertices, 871,414 triangles), we can compare GLB and JSON parse times on a Macbook Pro 16 inch. The JSON format took over 3 secs just to parse the data, a peak memory usage of ~498 MB and a gzipped package size of 28.1MB. GLB speeds ahead taking only 0.193 secs which is 17x faster, uses a peak of ~25.2 MB of memory and a gzipped package size of 25.7MB!

Codeplay Blog: SYCL for Safety Practitioners - a 3 part series

Codeplay recognized that there are few resources for safety practitioners and programmers looking at developing applications with SYCL that are required to meet functional safety requirements. This three part series of blog posts will give readers an overview of what they need to know about using SYCL in a safety-critical environment. The information is most relevant to safety practitioners working with SYCL, but equally will help to educate developers working on low-level drivers for DSPs and other processors.

Blog: Streamlining 3D Commerce with Material Variant Support in glTF Assets

In the world of e-commerce, many products come in different options, or variants. When shopping online, for example, colors and materials of a brand of shoe might have an image representing each option. And now, in addition to using 2D images, more and more retailers are starting to use 3D and AR to merchandise products in online channels to enable customers to more fully experience products or view items in their environment in rich 3D. Each time a customer views a different colored shoe, there’s a good chance that another complete 3D model is being loaded just to display that color variant. This leads to increased download times and wasted bandwidth as the files contain a lot of redundant data, including downloading exactly the same geometry multiple times. In turn this causes increased memory usage on the device, and slower interactivity, resulting in a poor customer experience. Learn how the Khronos Group and the 3D Commerce working group is improving this.

Vulkan and the technology behind Doom Eternal

For the release of the first add-on for Doom Eternal, we received the offer to talk to id Software’s lead engine programmer Billy Khan about the technology of the game and id tech in general. In the extensive interview, Billy unpacks details about the Vulkan API used, storage management, LoD and streaming systems and many other interesting aspects. This interview is originally in German, we are supplying a Google translate version in English.

NVIDIA Interview – Discussing Ray Tracing Support And ‘Proprietary’ Extensions with Vulkan

​WCCFTech has an interview with Brian Burke, NVIDIA PR Gaming Technology, Esports & Consumer VR. Brian stated that at NVIDIA, we “supports the use of industry standard APIs, such as DXR and the upcoming Vulkan Ray Tracing extension. Ahead of the release of the official Vulkan Ray Tracing extension, NVIDIA has enabled Vulkan developers to implement ray tracing via an NVIDIA extension.” Read the rest of the interview.

Ask an Expert: OpenVX Programming Guide

In this interview, authors Victor Erukhimov, Frank Brill, Stephen Ramm and Radhakrishna Giduthuri are asked about their new book OpenVX Programming Guide, and uncover the unique quality a book can have from being written by a team of authors.

What is the approach of your book that will help the reader get the most out of OpenVX?

The book starts with the introduction to the OpenVX high level concepts, and then discusses each functional block by solving a model problem, reviewing in detail the sample code that is available on GitHub.
