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.

Learning from Home with 3D Content

In the last several weeks learning has moved from the classroom into the home, as schools across the world have temporarily closed. The old way of learning involved reading textbooks or consuming content delivered through paper handouts. Simply Augmented is using the Smithsonian “Open Access” initiative trove of artifacts to bring 3D into your home. Simply Augmented began the process of converting the Smithsonian 3D assets into web-ready, augmented reality files and then posting them to their 3D sharing platform, Simply3D, for free. Simply3D is an easy way for anyone to host and share augmented reality assets.

Amazon Sumerian supports exporting your scenes to glTF

Amazon Sumerian, the AWS service that makes it easy to create and run browser-based 3D, augmented reality (AR), and virtual reality (VR) applications, now supports exporting your Sumerian scenes to glTF (GL Transmission Format), an open-source file format for 3D scenes and models that’s compatible with many other 3D editing tools and rendering engines. To learn more about the glTF file format and what is supported, please refer to our user guide.

TurboSquid updated StemCell with glTF support in 2018, following Microsoft’s use of the format for their ‘3D For Everyone’ initiative. Microsoft’s embrace of glTF has extended to its Hololens program, making glTF a standard format for use in AR/VR and other immersive content. StemCell, meanwhile, gives content creators a specification for building content to ensure it will work well in their marketplace but the broadening use of glTF means the models will work on other sites supporting glTF. TurboSquid is also part of the Khronos 3D Commerce Initiative, which is a coalition of companies including Target, Google, Adobe, Ikea, and many others that are working together on glTF for online commerce.

3D Tiles is widely accepted by companies in the geospatial industry. Support for glTF and WebGL means that applications using 3D Tiles can be accessed in all browsers. The reliance on accepted standards means that developers have access to a wealth of open source resources.

With the release of version 2020.1, Datakit’s tools for writing in glTF format are available both for developers via the CrossCad/Ware software development kit (SDK), and for end users via the CrossManager standalone software.

DGG investigates the possibilities and current status of 3D experiences for E-Commerce. Looking at industry members joining the Khronos Group 3D Commerce Working Group, glTF, 3D web-apps, mobile Augmented Reality (AR) and Virtual Reality (VR) applications. DGG first analyzes the benefits of 3D experiences for retailers and describes typical 3D processing workflows in practice and highlight technical challenges, as well as potentials for enhancing scalability and reducing costs.

Khronos and Smithsonian Collaborate to Diffuse Knowledge for Education, Research, and Creative Use

Today, The Khronos Group and the Smithsonian, the world’s largest museum, education and research complex, with 19 museums and the National Zoological Park, announce their Collaborative Agreement for the increase and diffusion of knowledge using 3D scanned models from the Smithsonian collections. Working with Khronos, the Smithsonian publicly launched their Open Access initiative today, which included the release of approximately 2.8 million 2D images and 3D models into the public domain with the internationally recognized Creative Commons Zero (CCO) license. Additionally, a variety of platforms will be launched to make its collection media, collections data, and research data available for educational and research endeavors, creative reuse, computational analysis and innovative explorations. Watch the launch of the Open Access initiative on YouTube.

Khronos recently hosted a webinar about the latest open source glTF tools from Khronos and Blender, including the Blender glTF I/O, glTF Compressonator, and glTF Sample Viewer. The basic workflow demonstrated in this one-hour webinar started with a ray-traced 3D model in Blender, exports it to glTF, sets up image-based lighting using the glTF Compressonator, and finally deploys the assets to the glTF Sample Viewer. The goal was to help attendees understand the upcoming challenges for the production pipeline regarding the adaption of real-time 3D products rendering. There is a short question & answer period at the end of the webinar. Both Video and Slides are now available online.

As glTF adoption has accelerated, its ecosystem has grown into an abundant trove of tools and applications that can generate and import glTF files. However, this ever-growing diversity has created an urgent need for an efficient tool to catalogue glTF resources across the industry—and to enable developers and artists needing to generate or use glTF assets to find the best tools for their projects. To fulfill this community need, Khronos has created the glTF Project Explorer as a centralized searchable directory of projects within the glTF ecosystem.
