Cesium for Unreal Now Available

Cesium has announced that Cesium for Unreal is now available! Cesium for Unreal is free and open source under Apache 2.0 license. The plugin is built to unlock the entire 3D geospatial ecosystem in the Unreal Engine by combining a high-accuracy, full-scale WGS84 globe, open standards, 3D Tiles and glTF. Download today to visualize massive high-resolution, real-world photogrammetry and 3D content at runtime using 3D Tiles.

The Khronos Group and Web3D Consortium Deepen Cooperation on Open Standards for 3D on the Web

The Khronos Group and Web3D Consortium have entered into a liaison agreement to advance Web-based 3D visualization, modeling and streaming. The liaison is designed to foster interoperability and synergy between the X3D and glTF open standards. The organizations will begin collaborating with a shared goal to integrate glTF 2.0 into X3D V4 to improve visualization and streaming of 3D data.

Cesium for Unreal coming March 30

Cesium has announced that Cesium for Unreal will be available for download on March 30, 2021. It will be free and open source under Apache 2.0 license. The plugin is built to unlock the entire 3D geospatial ecosystem in the Unreal Engine by combining a high-accuracy, full-scale WGS84 globe, open standards, 3D Tiles and glTF.

migenius releases RealityServer 6.1 with new glTF 2.0 Importer

glTF has become such an important format that migenius needed more direct control over the way it was imported into RealityServer. To that end, RealityServer’s glTF importer has been re-written from the ground up. RealityServer still supports everything in the previous importer, but it has now added support for several more ratified extensions, further reducing the need to pre-process glTF files with unsupported extensions. The complete list of supported extensions is now as follows:

HERE Premier 3D Cities leverage the power of 3D Tiles and glTF

At CES 2021, HERE Technologies announced its release of HERE Premier 3D Cities, high-fidelity 3D models of 75 city centers around the world, with the goal of enabling transformative augmented reality applications, from supply chain management to vehicle navigation.

To deliver high-resolution 3D geometry over the web, HERE chose to use OGC’s “future-proof” 3D Tiles standard, originally created by Cesium and leveraging The Khronos Group glTF open standard. HERE’s 3D cities demonstrate that Khronos Group and OGC standards are successfully enabling the 3D graphics and 3D geospatial communities to achieve scaling, performance, and interoperability. 3D Tiles and glTF also enable HERE cities to include data layers and attributes aligned to physical geometry and terrain, and each structure is indexed and addressable, with accurate volume size, elevation, and color.

Godot Introduces glTF 2.0 Scene Exporter

For Godot 4.0, a bidirectional workflow with glTF was implemented to allow for a combination of in-engine and out-of-engine tooling to work seamlessly. Importing glTF scenes has been supported since Godot 3.0, and with this release you can now export your Godot scenes to glTF and then imported into other apps to make edits continuously. This workflow means you can work on your scene in Blender and then bring it back into Godot for more work.

Catching up after the Khronos 3D Commerce Working Group Webinar - Q&A

Recently, the Khronos 3D Commerce Working Group hosted a webinar to discuss its activities, including why industry alignment on the glTF file format (the “JPEG for 3D”) is crucial, and how standardization will bring new opportunities to any designer, retailer, manufacturer or technology company developing 3D experiences. The panel was led and moderated by Leonard Daly, President of Daly Realism, who was joined by industry experts from Wayfair, UX3D, Amazon Imaging Services, Autodesk, DGG, DreamView, Microsoft and Shopify. At the end of the webinar, the audience submitted questions for the panelists. The answers as a Q&A are now available online.

glTF Validator and glTF Tools for VSCode updated for new PBR Extensions

Lots of exciting glTF news today! Khronos announced three new new Physically Based Rendering extensions for Clear Coat, Transmission and Sheen which continues to build a powerful, interoperable, material model for the glTF ecosystem. As well, new versions of glTF Validator (2.0.0-dev.3.3) and glTF Tools for VSCode (2.3.2) were also published today, adding support for all three of the PBR extensions.

Khronos Releases Wave of New glTF PBR 3D Material Capabilities

Today, The Khronos Group announces the release of a set of new Physically Based Rendering (PBR) material extensions for glTF. glTF is Khronos’ royalty-free format for widespread, efficient transmission and loading of 3D scenes and models, known in the industry as the ‘JPEG of 3D’. PBR enables developers and artists to achieve photorealism through rendering parameters that correspond to real-world physical properties of materials in 3D assets. These new extensions for Clear Coat (KHR_materials_clearcoat extension), Transmission (KHR_materials_transmission extension) and Sheen (KHR_materials_sheen extension) build on the existing PBR capabilities of glTF 2.0, and together with additional upcoming extensions, are creating a powerful, interoperable, physically-based material model for the glTF ecosystem.

Faster Load Times with glTF’s GLB Format

The PlayCanvas team announced the Editor support of glTF GLB conversion with model and animation imports. This gives developers an order of magnitude reduction in load times compared to the JSON format while keeping similar gzipped download size. Using the Stanford Dragon model (2,613,679 vertices, 871,414 triangles), we can compare GLB and JSON parse times on a Macbook Pro 16 inch. The JSON format took over 3 secs just to parse the data, a peak memory usage of ~498 MB and a gzipped package size of 28.1MB. GLB speeds ahead taking only 0.193 secs which is 17x faster, uses a peak of ~25.2 MB of memory and a gzipped package size of 25.7MB!

Blog: Streamlining 3D Commerce with Material Variant Support in glTF Assets

In the world of e-commerce, many products come in different options, or variants. When shopping online, for example, colors and materials of a brand of shoe might have an image representing each option. And now, in addition to using 2D images, more and more retailers are starting to use 3D and AR to merchandise products in online channels to enable customers to more fully experience products or view items in their environment in rich 3D. Each time a customer views a different colored shoe, there’s a good chance that another complete 3D model is being loaded just to display that color variant. This leads to increased download times and wasted bandwidth as the files contain a lot of redundant data, including downloading exactly the same geometry multiple times. In turn this causes increased memory usage on the device, and slower interactivity, resulting in a poor customer experience. Learn how the Khronos Group and the 3D Commerce working group is improving this.

One challenge to deploying 3D at scale lies in its interoperability, or rather, in its lack thereof. Whilst the dream is to create a fully end-to-end digital workflow made up of previously siloed platforms that now seamlessly integrate and communicate, the reality is that 3D tools today don’t play particularly well with others. This Spotlight offers a roadmap to achieving simple integration and subsequent seamless data flow to underpin a future digital supply chain. You can view all of the panel discussions here:
