A new blog post on UploadVR provides a blueprint for people to think about the spatial computing revolution over the next six years. Part of this future looks how a combined roll-out of OpenXR with the broader adoption of formats like glTF may allow us to start to see the underpinnings of an actual interconnected universe like the OASIS or Metaverse.
Draco is a glTF extension for mesh compression along with an open-source library developed by Google to compress and decompress 3D meshes to significantly reduce the size of 3D content. Cesium has been collaborating with Khronos and Google to make Draco a glTF extension, and you can now load Draco compressed models and 3D tilesets in Cesium. Learn more about Draco, how it works and what it has to offer.
glTF continues to gain strong industry momentum with new support from major players including Facebook, Adobe, Epic, and Unity, in addition to the ongoing support from the grassroots open-source community. Facebook’s recent adoption of glTF 2.0 enables its users to place and see 3D content in their News Feeds, underscoring the social media platform’s plan to enable users to bring 3D objects and assets with them across AR, VR, mobile, and web experiences — using open standards. Khronos has released new glTF testing tools, samples, and exporters to support this growing ecosystem.
Sketchfab has just announced a download API for their entire 3D catalog. The API lets you search by titles, tags, categories, polygon count and more. The initial scope of the download API lets you import content available under a Creative Common license – more than 150,000 3D models available today – in glTF format. As a step two, the API will also let you easily import your own content, as well as content you purchased on the Sketchfab store. Alongside the release of the download API, Sketchfab introduces import add-ons for Unity, Unreal and Godot, as well as native integrations with Torch3D, Minsight, Spatial stories, Selerio, StellarX, Valorem’s Holobeam, AnimVR, Plattar, Sketchbox3D and Looking Glass.
This years Khronos Developer Day Sessions were the biggest yet, with over 1500 people attending. Most of the sessions were standing room only. Khronos would like to thank the attendees, the speakers, and the support staff who made this day possible. It’s not over yet! On Thursday night there will be a WebGL & glTF Meetup. And, if you were not able to make it to GDC this year, we’ve you covered as well. The presentations are online, video of the sessions will appear online later this week, and we have all your favourite Khronos Standards Merchandise for gals and guys available online.
Verge3D is based on WebGL and integrate a glTF exporter. Verge3D enables developing and publishing models, scenes and entire 3D web applications online. Verge3D includes a visual editor called Puzzles which allows for setting up interactive scenarios for your web apps. This tool is based on Google’s Blockly framework used in education and other industries. If you are a 3D artist, you will appreciate Puzzles which gives you the power to directly express your creativity in the realm of interactive 3D Web.
Starting today, Facebook is rolling out support for the industry standard glTF 2.0 file format for Facebook 3D posts. 3D objects or scenes saved in glTF can be dragged straight to a browser window to add to your Facebook account. The company is also adding the feature to its platform tools so developers can build ways to export creations to Facebook from various apps. With glTF 2.0 support, Facebook is opening up even more ways to share 3D content on Facebook from more creation tools and platforms. They’re introducing new Graph API endpoints with 3D Post support so developers can build seamless 3D sharing into any app — letting people share interactive objects or scenes directly to Facebook with just a click. Learn more about glTF and what Facebook is doing here, and check out a cool example of glTF in action here.
The Khronos Group announces the release of a geometry compression extension to glTF 2.0 using Google Draco technology to significantly reduce the size of glTF models and scenes. The Khronos glTF Draco extension specification is accompanied by optimized, open source compression and decompression libraries on the Draco GitHub site to enable the rapid deployment of glTF compressed geometry into tools, engines, applications, and browsers everywhere.
The Khronos™ Group, an open consortium of leading hardware and software companies creating advanced acceleration standards, announces the release of a geometry compression extension to glTF™ 2.0 using Google Draco technology to significantly reduce the size of glTF models and scenes. The Khronos glTF Draco extension specification is accompanied by optimized, open source compression and decompression libraries on the Draco GitHub site to enable the rapid deployment of glTF compressed geometry into tools, engines, applications, and browsers everywhere.
Standards make life easier, and we depend on them for more than we might realize — from knowing exactly how to drive any car, to knowing how to get hot or cold water from a faucet. Balancing the need for a stable standard, while at the same time allowing technology advances to be rapidly exploited, is a big part of what Khronos does. There are two ways a Khronos standard can be extended: Vendor Extensions and Khronos Extensions. Read on to learn how both of these work within Khronos.
Unreal Engine 4.19 preview has a experimental importer for glTF. This is an open format, that, once final, should work better than FBX, and actually work great with Blender. The Unreal Engine forums mentions that “Right now its much superior to FBX for some simple cases. The cool point about glTF is that the same file holds a full scene, with multiple 3d objects, each of them with animation, and each of them with materials, and each material actually imports as a material graph, and with textures.” Take a look and tell us what you think.
The Khronos Group will be at GDC & VRDC 2018. Be sure to mark us in your calendar for the Khronos Dev Day on March 19th in Moscone, West Hall, Room 3022. This years sessions are now posted and include WebGL, glTF, OpenXR and Vulkan. Be sure to book mark the Khronos GDC event page and checkout some of our other upcoming events and meet ups.
Startup Sketchfab is taking one of its biggest steps yet today and launching features so that users can buy and sell 3D objects. The company is supporting the industry standard glTF as its download format, which should make it easy for creators to take the objects purchased from the site and import them into creativity software.
Authoring content for a new file format can be exciting, liberating, and at the same time scary. To be the most efficient and avoid frustration, it helps to understand the format’s requirements. To help achieve this, Patrick Ryan from Microsoft has created a walk through following several paths for authoring content in the glTF format as well as outlining specific settings to maximize your success. Patrick touches on both free and commercial software packages to ensure everyone has a path into glTF. Let’s get going… check out this glTF how-to.
