Mesa's Venus, a Vulkan driver within the Mesa 3D graphics library, now exposes accelerated Vulkan API support within virtualized environments (VMs). On the Virglrenderer side for the host renderer bits of Vulkan 1.4, this merge took Vulkan 1.4 over the finish line with virglrenderer.

This Rastergrid blog explores the creation of the Vulkan SC Emulation driver stack. This software stack enables all developers to prototype and develop Vulkan SC applications on consumer PC hardware running Windows or Linux without needing specialized hardware and software components that are typically required to target safety-critical systems.

The Khronos OpenXR Working Group recognizes the challenges developers have faced with legacy APIs and platform-specific behaviors that limit XR application portability. The Working Group is dedicated to evolving OpenXR by incorporating vendor extensions into the core specification and continues to enhance platform interoperability. Today, three major engines - Unity, Unreal, and Godot - support building OpenXR applications that are compatible with multiple vendors' OpenXR conformant devices, provided vendor-specific features are avoided. 

Application developers retain the choice to target specific runtimes and devices if desired, though this approach may introduce some vendor dependencies. For guidance on building OpenXR PCVR applications on Windows without vendor dependencies:

• Setting up Cross-device OpenXR on Unity For Windows PCVR
• Setting up Cross-device OpenXR on Unreal Engine For Windows PCVR
• Setting up Cross-device OpenXR on Godot For Windows PCVR

In this video from SC24, SYCL Chair Dr. Tom Deakin shares strategies for writing performance portable applications and presents the roles that ISO languages C++ and Fortran, as well as parallel programming models and abstractions such as OpenMP, SYCL, and Kokkos, play in the ever-changing heterogeneous landscape. 

SuperDNA's Mike Festa sits down with the Chair of the 3D Commerce Working Group, Dan Frith, to discuss Khronos and the exciting world of 3D Commerce. 

In this Bently blog, we learn how Bentley, through acquisition of Cesium, has come to embrace the Khronos Group ecosystem. As digital twin and infrastructure modeling technologies mature, Bentley’s involvement is helping to shape an open, connected, and interoperable future for infrastructure.

SuplerSplat 2.0, a open source platform built on WebGL, WebGPU, and WebXR has been released. Publish your splats to the web, create cool camera flythoughs, explore splats from the community and immerse yourself with AR and VR with the latest SuperSplat software from PlayCanvas.

DGG recently contributed a stunning Car Concept model to the glTF Sample Assets repository. The asset was started from a public domain, then was optimized and converted into a well-formed glTF asset, to showcase the potential for high graphical quality in glTF while maintaining a small download size.

In this Codeplay blog, they examine the limitations of the current SYCL images API design and demonstrate how the bindless images extension addresses these challenges. They explore the extension’s core concepts, walk through a practical example, showcase its key benefits, and discuss our plans for the future of bindless images in SYCL.

The Vulkan SC Emulation driver stack enables all developers to prototype and develop Vulkan SC applications on consumer PC hardware running Windows or Linux without needing specialized hardware and software components that are typically required to target safety-critical systems. The release of the Vulkan SC Emulation driver stack at the end of 2024 marked another milestone in the evolution of the Vulkan SC Ecosystem toolchain.

The Khronos 3D Formats Working Group is developing a new addition to the glTF ecosystem that will revolutionize how complex 3D scenes are built on the Web. While glTF, the widely-adopted asset open standard for 3D web content, typically handles one asset at a time, this addition will enable creators to efficiently combine multiple glTF assets into sophisticated scenes. The 3D Formats Working Group is still weighing whether this project will ultimately be released as a glTF extension or an entirely new format. In this blog, we discuss the “glTF External Reference Format.”

Help shape the future of the Vulkan developer ecosystem! The 2025 LunarG Ecosystem Survey is now live. A few minutes of your time will help us chart the course and set priorities for the upcoming year. Survey closes on February 19, 2025.

LunarG describes how they improved startup time by a factor of 10 by employing four main strategies to accelerate the process: leveraging the DontInLine flag, segmenting instrumentation, utilizing Vulkan robustness features, and optimizing for graphics pipeline libraries. Click through to learn more about these strategies and a bonus tip!

The Khronos Group's Alexey Medvedev and Dan Frith joined Kent Bye on Voices of VR earlier this week to discuss the evolution of glTF as a spatial format and the use cases for external references. The recording is now available.
