Earlier this week, at the Microsoft Windows 10 Event in New York, Microsoft shared their vision around 3D for everyone. As part of achieving that vision Microsoft announced they are joining the 3D Formats working group at Khronos to collaborate on its GL Transmission Format (glTF).
This tool converts COLLADA (.dae) models or OBJ models to glTF for use with Cesium. You may upload one at a time or multiple models with drag and drop. You can also select a single zip file containing both model and textures or drag and drop them together onto the canvas below. Once uploaded, a self-contained glTF file will be downloaded and a model preview will be shown below.
The Khronos Group today announced significant momentum behind the glTF (GL Transmission Format) royalty-free specification for the transmission and loading of 3D content. Since the launch of glTF 1.0 in September 2015, Khronos has released an open source glTF validator, commenced community review of the glTF 1.0.1 specification that incorporates industry feedback for enhanced interoperability, successfully registered glTF as a MIME type with IANA and has catalyzed a growing array of importers, translators and tools supporting the glTF standard. More information on glTF specifications and activities is available on the Khronos website. Read the press release.

Both AMD and Khronos Group now have their GDC related presentations online. You will find the AMD list of presentation on their new GPU Open website. Khronos has their presentations and videos listed on their event page archive.
The Khronos Group has put out a request for quote (RFQ) for a glTF Validator. The primary goal of this project is to create a glTF Asset Validator: a tool to validate that a glTF asset conforms to the glTF spec. This will be used to validate pipeline tools such as converters, exporters, and optimizers. Complete information is available online.
The Khronos Group is holding a series of sessions today in San Francisco. If your are at GDC, take a break and a 5 minute walk over to Green Space to see one of the several sessions Khronos will be hosting. Start the day off with Jon Peddie Research at 8:30AM PT. After a short break there will be 3 back-to-back sessions: WebGL+glTF at noon, Khronos Chapters lunch at 1PM and Vulkan at 2PM. Ending the day off will be a large Khronos Social from 7PM-9:30PM. All the details you need are on the Khronos event page. Unable to attend? No worries, Khronos has you covered with a Livestream of both the WebGL + glTF session and the Vulkan session. We're expecting a lot of people today and space is limited. Please be sure to register for one of the few remaining spots if you haven't done so already.
xeoEngine is an open-source WebGL-based 3D visualization engine which supports glTF as its native data format. xeoEngine intentionally does not yet load animations, cameras and lights from glTF. Instead, it focuses on loading static models while allowing us to access their components via its scene graph API, so that we can programmatically rig them with our own tweens, lights, cameras and so on. Also, xeoEngine currently ignores glTF shaders, opting instead to rely on its own internally-generated shaders.
The Khronos Group will be hosting a series of sessions again this year at Green Space in San Francisco. Lined up this year on March 16th will be sessions on WebGL, glTF, Chapters and Vulkan. A Khronos Social for developers to meet and chat with the developers that create some of the Khronos APIs will wrap up the day. Starting the day will be the now famous JPR Press Briefing on the Gaming Market. Complete details and registration for the Khronos sessions are available online. For anyone that cannot make the sessions, we will have live streaming and videos of the event will be available afterwards.
The week of March 16th is a busy one so be sure to add the annual Khronos Group sessions to your calendar. This year we have a great line up including Vulkan, WebGL and glTF. There will be a special Chapters Luncheon and after the day winds down join Khronos for a special evening social full of good conversation with the Khronos Group members who bring you Vulkan, WebGL, OpenGL, and more. Register today for all the sessions you will attend.
Cyrille Fauvel will present a short overview of the glTF format – a specification for the efficient transmission and loading of 3D scenes and models by applications – followed by a more detailed discussion and demonstration of the FBX to glTF converter that he has recently created.
