Google and Binomial Contribute Basis Universal Texture Format to  Khronos’ glTF 3D Transmission Open StandardEarlier today, Google and Binomial announced that they have partnered to open source a sophisticated texture compressor and a high-performance transcoder for Binomial’s cross-platform Basis Universal texture format. This format can help solve a long-standing problem in the 3D ecosystem: how can 3D textures assets be efficiently packaged or transmitted for an application in a way that is both compact AND can be efficiently processed by the wide diversity of GPU hardware texture engines - each of which has a preferred native format?

Max Limper has written a guest post on the Zeiss blog about 3D data optimization for VR, AR and the Web. He also discusses #glTF and the 3D Commerce Exploratory Group. Zeiss and DGG are contributing to the The Khronos Group 3D Commerce Exploratory Group. Max was awarded with the Hugo-Geiger-Prize of the Fraunhofer society, in recognition of his dissertation entitled “Automatic Optimization of 3D Mesh Data for Real-Time Online Presentation”. Regarding the topics of efficient binary encoding and realistic PBR materials, Max also contributed to the current glTF 2.0 standard. During August 2018, Max became a co-founder of DGG (Darmstadt Graphics Group GmbH), a Khronos member.

Esri CityEngine 2019.0 was just released. CityEngine now supports glTF and GLB (binary glTF) for both import and export. Note that also the PBR material attributes of glTF 2.0 can be read, edited and written. You can find the complete release notes on the ArcGIS website here.

Diligent Engine now supports GLTFDiligent Engine is a modern cross-platform low-level graphics library and rendering framework. In a recent update, Diligent Engine enabled support of GLTF 2.0 format. It also implemented physically-based renderer with image-based lighting and released cross-platform GLTF viewer as example application.

Khronos will be holding their Annual GDC Developer Day Sessions on March 19th in Moscone West Room 2020. The complete schedule is available online:

  • glTF and WebGL - 10:00am – 11:00am
  • OpenXR – State of the Union – 11:20am – 12:20pm
  • Vulkan – State of the Union - 1:20pm – 2:20pm
  • Making Use of New Vulkan Features – 2:40pm – 3:40pm
  • Bringing Fortnite to Mobile with Vulkan and OpenGL ES – 4:00pm – 5:00pm
  • Ubisoft's Experience Developing with Vulkan – 5:30pm – 6:30pm
Running all day March 18-19 will be the Khronos OpenXR Table at VRDC. Finally on March 20th starting at 6:30pm, there will be the annual WebGL/WebVR Meetup to be held in Galvanize. In past years there were over 200 people attending with only standing room and people being turned away. If you want to get in, show up early. This event will be live streamed on the Silicon Valley WebGL group on Facebook.

To jointly advance accessibility of 3D geospatial content, The Khronos Group recently formalized a liaison with the Open Geospatial Consortium (OGC). One of the first victories of this collaboration between the computer graphics and geospatial communities is a new OGC Community Standard addressing massive scale 3D pioneered by longtime Khronos contributors, the Cesium team. Learn more about the Liaison and new Standard in the Khronos blog post.

Khronos Group at GDC 2019 - Developer Day sessions, OpenXR Table and WebGL MeetupIf you are attending GDC 2019, be sure to mark March 19th in your calendar. Khronos will be hosting the annual Developer Day sessions in the Moscone West, Room 2020 from 10am to 6:30PM. This year there will be six (6) sessions covering glTF, WebGL, OpenXR, Vulkan and OpenGL ES. There will also be an OpenXR table at VRDC where you can learn more about OpenXR, talk with OpenXR working group members, and learn how your company can implement or join in the development of this important industry standard. The Khronos Group is once again sponsoring the WebGL/WebVR Meetup. Last year we had over 200 RSVPs and an amazing lineup of speakers. Join Khronos member Patrick Cozzi (Cesium) and other speakers for this gathering of the Silicon Valley WebGL/WebVR meetup group.

Khronos announces newest Associate Member DGGThe Khronos Group would like to welcome its newest Associate Member DGG (Darmstadt Graphics Group GmbH). DGG develops RapidCompact, a software that reduces the size of 3D data sets in a fully-automatic fashion, optimizing 3D models for different use cases such as VR, AR and 3D on the Web. Being a spinoff of the Fraunhofer Society, DGG embraces innovation as well as standardization efforts, which has made them a strong supporter of Khronos’ glTF format.

COMSOL Multiphysics Supports glTF File Export for 3D Simulation ResultsThe latest release of COMSOL Multiphysics, version 5.4, includes a new postprocessing feature: the ability to export 3D simulation results plots as GL Transmission Format (glTF) files. 3D results can be exported in just a few clicks and by specifying a file path and name. glTF files are then ready to be opened in any applicable graphics tool or third-party graphics viewer so that you can display and manipulate the 3D results — and even superimpose them on a customized background! Learn more about how to export your 3D simulation results as glTF files and share them via viewers in this post on the COMSOL.

The Microsoft Mixed Reality Extension SDK is an open source project under the MIT license which lets developers and community members extend the AltspaceVR host app's worlds with multi-user games and other dynamic experiences. Among many other things, the SDK enables you to create extensions that can modify the scene graph by loading glTF assets and scene files, instantiating primitives or the host app's built-in assets, or programmatically build meshes.

Students of Patrick Cozzi, glTF Working Group Chair, in the GPU course at University of Pennsylvania will be live streamed Monday, December 10, at 6pm EST. The students have built final projects with everything from WebGL to Vulkan to CUDA to DXR - ranging from photon mappers to water sims to feature detection algorithms. Many of the projects use glTF for models.
