3D Commerce Panel to discuss progress on specifications and guidelines

Join the Khronos Group for a 3D Commerce Panel to discuss progress on specifications and guidelines on October 27, 2020. In order to scale 3D experiences and make them truly mainstream, standardization is a critical next step. Panelists will discuss why industry alignment on a “JPEG for 3D” is crucial and how standardization will bring new opportunities to any designer, retailer, manufacturer or technology company developing 3D experiences. Space is limited, please register early.

Blender2MSFS - this Blender addon allows you to create 3D assets for Microsoft Flight Simulator (2020). The addon is designed for Blender 2.83, and above. MSFS is using the Khronos’ glTF 2.0 file format with multiple custom extensions and extras for special material functions. While Blender 2.8x already ships with a glTF exporter, some changes had to be made to the exporter to facilitate some of the used extensions. These changes come fully integrated into this addon, in the form of modified call functions. These functions will make use of the existing Khronos glTF 2.0 exporter, while inserting some of the custom extensions for MSFS

Blog: Live glTF Asset Editing in Your Browser—Even in AR

Things are quickly improving for 3D on the web, with WebXR gaining support in more browsers and <model-viewer> achieving API stability. <model-viewer> is an open source web component that brings glTF™-based interactive, accessible 3D content to your website with a single line of HTML, including AR placement on both Android and iOS. New with v1.1 of <model-viewer> is a scene-graph API that allows basic access to the glTF model source, enabling simple edits to be made to 3D assets with just a few lines of JavaScript. Learn how to edit glTF assets in your browser with model-viewer.

Darmstadt Graphics Group (DGG) launches RapidCompact 4.0 with glTF support

Darmstadt Graphics Group (DGG) is pleased to announce the launch of their in-browser automated 3D optimization solution - RapidCompact 4.0 - in time for SIGGRAPH 2020. RapidCompact automates the creation of high-quality optimized 3D assets for web, mobile, and AR or XR platforms. It takes large, complex 3D assets and turns them into compact content which can be viewed on any device. DGG is one of 80 leading retail, hardware, and software companies participating in the 3D Commerce Working Group.

Editing glTF: Possibilities, Challenges, and Insights from UX3D

In this guest blog, Norbert Nopper, Managing Director at UX3D, discusses editing glTF models and introduces a new visual glTF editor, Gestaltor. Norbert discusses how to directly edit glTF models and when that may lead to higher productivity when creating 3D models. Starting with a brief introduction to glTF and common workflows and discussing the possibilities and challenges involved in directly editing glTF asset files. Wrapping up with examples of how direct glTF editing may save you time production pipeline.

In this academic paper, the API employed for geovisualization use Web Graphics Library (WebGL), a cross-platform and royalty-free web standard for a low-level graphics API, designed and maintained by the non-profit Khronos Group. The implementation of the standard is a JavaScript API for rendering interactive 2D and 3D graphics within a web browser without a plug-in as the API closely conforms to Open Graphics Library for Embedded Systems (OpenGL ES) that can be used in Hypertext Markup Language 5 (HTML5) canvas elements

<model-viewer> v1.0 has been released. Combined with #webxr on Chrome Android your custom HTML/CSS flows naturally from 3D into #AR. You can try it here and view the change long on GitHub.

In February 2020, Arm made its open source ASTC encoder available under the widely accepted Apache 2.0 license, enabling developers everywhere to easily generate ASTC textures during application development. Meanwhile, Khronos’ glTF™ 3D asset format standard, is adding ASTC support to enable glTF Universal Textures to be decoded into ASTC on the fly on the target system. With these recent developments we wanted to reach out to the developer community to explore how ASTC is being used, and whether there are remaining barriers to adoption that Khronos and Arm can help address. Consequently, Arm conducted a game developer survey to learn.

Laval Virtual asserts its expertise and its role as a facilitator in virtual reality with 6 conference cycles: VRtical, TransVRsal, ConVRgence, Virtual World, Art and Tech Talk. There will be two talks this year that are Khronos related:

  • Unifying Reality: Building Experiences with OpenXR - Ryan Pavlik (Collabora)
  • Building the Metaverse one open standard at a time – Khronos APIs and 3D asset formats for XR - Neil Trevett (President, The Khronos Group)

April 2020 marks the 50th anniversary of Apollo 13’s historic space flight. Twenty years ago in 2000, AGI and noted space author Andrew Chaikin teamed up to tell a part of the story that they unearthed and validated with the help of original mission personnel. This video has been updated in 4K with glTF models.

Video Series: glTF Model Authoring Pipeline

In this video series, Alex Wood and Ed Mackey create a glTF 3D model of a Cubesat from reference images, using Blender, VSCode, and other tools. They walk through the glTF model authoring and texturing process from scratch to a finished result, and show the result being used in STK and other apps that consume glTF models.
