The new VK_EXT_descriptor_buffer extension will change how engines approach descriptors going forward. Descriptor sets are now backed by VkBuffer objects where you memcpy in descriptors. In the following blog, Hans-Kristian Arntzen, gives us an overview of the new extension including the history, reasoning, and how to implement.

At Mercedes-Benz Research & Development North America, we develop and certify cars for the U.S. and the world in six locations. Our work ranges from EV battery research to hybrid powertrain calibration and certification, from telematics to autonomous driving software, and from advanced exterior design to UX. It’s not just about cars, it’s also about creating the latest and greatest software, cutting-edge technology, and groundbreaking innovation.

First introduced in 2014 by the Khronos Group®, SYCL™ is a C++ based heterogeneous parallel programming framework for accelerating high performance computing (HPC), machine learning, embedded computing, and compute-intensive desktop applications on a wide range of processor architectures, including CPUs, GPUs, FPGAs, and tensor accelerators. SYCL 2020 launched in February 2021 to bring a new level of expressiveness and simplicity to developers programming heterogeneous parallel processors using modern C++, and further accelerating the deployment of SYCL on multiple platforms, including the use of diverse acceleration API backends in addition to OpenCL™.

Khronos has officially adopted ‘Kamaros’ (pronounced Kam-ă-ross) as the name for the Embedded Camera System API and the associated working group. Jointly promoted by Khronos and the European Machine Vision Association (EMVA), the Kamaros API Working Group is developing an open, royalty-free standard for controlling camera system runtimes in embedded, mobile, industrial, XR, automotive, and scientific markets.

The Khronos 3D Formats Working Group is constantly assessing emerging requirements of the glTF ecosystem and asking how the group can make the most impactful progress. Over the past 18 months, one issue has consistently bubbled to the top of these discussions: interactivity.

The urgency of developing new interactivity and behaviors capabilities for glTF has been fueled in part by the evolution towards the open metaverse. It’s clear that glTF can and should have an important role to play in this ecosystem, but we have some important functionality gaps to close first. We’ve spent the past few months cooperatively refining proposals for how we might build interactivity into glTF 3D assets. This blog will outline our current approach and reasoning, as well as invite the community to weigh in.

Join the Khronos 3D Formats Working Group and the glTF community at our virtual meetups. During each session our expert presenters will share use cases, best practices, tooling updates, and live demos, plus answer your questions live.
