Cesium announce the release of Cesium 1.15. Highlights include: Support for glTF 1.0 and the KHR_binary_glTF and KHR_materials_common extensions. Also, updated the online model converter to output glTF 1.0; Decreased GPU memory usage in BillboardCollection and LabelCollection by using WebGL instancing; New CZML examples thanks to Tiff Lu and Adam Cole from the University of Pennsylvania.
Khronos announced that the glTF™ 1.0 (GL Transmission Format ) royalty-free specification for transmission and loading of 3D content has been finalized for Ratification and is immediately available for use by tools and application vendors. glTF is an efficient, interoperable asset delivery format that compresses the size of 3D scenes and models, and minimizes runtime processing by applications using WebGL™ and other APIs. glTF also defines a common publishing format for 3D content tools and services.
During this virtual AR Community meeting on Thursday October 15, 2015 participants will learn about the status of the Khronos Group glTF specification, experiences with implementation and we will discuss the role of glTF in reducing the complexity and bandwidth of compressing and transmitting 3D assets for use in AR experiences. Presenters will share the work the Khronos Group members are doing, trends in use of glTF and how this will impact AR. Speakers include: Neil Trevett, VP NVIDIA and President Khronos Group; Patrick Cozzi, Cesium and Marius Preda, Institut Telecom Sud-Paris.
Next week Patrick Cozzi will be giving a talk on the state of WebGL and glTF at the Graphical Web conference. He will have some exciting progress to share on glTF, and he also wants to capture the state of the entire WebGL ecosystem. If you are working on a WebGL engine, tool, or browser/driver/platform, and want Patrick to include an update for it, please contact him with the details by the morning of Friday September 18th. The slides will be posted online afterwards.
glTF is an up and coming format for transmitting 3D models, tailored for WebGL and OpenGL they like to think of it as a 3D model codec. There's three.js and Node.js support, as well as a COLLADA and separate FBX converter. There's more explanation of glTF in the presentation at the WebGL BOF. Compression progress here, discussion here. Special thanks to Patrick Cozzi and the folks over at Real-Time Rendering Blog.
The Khronos Group has added another Request For Quote (RFQ). This one is to update the glTF three.js loader on GitHub to reflect the latest versions of the glTF specification and three.js library, and to drive feedback into the final glTF 1.0 specification. Complete details for glTF, OpenGL ES, SPIR-V and OpenVX RFQs available online.
CesiumJS just released a demo streaming over 135,000 buildings in Washington, DC using tiles of glTF in Cesium. The demo is fairly fast and there are more optimizations to come. Over 135,000 measurement-quality structures with rooftops from CyberCity 3D.
Cesium uses the web-friendly glTF format for 3D models. Cesium provides an online COLLADA-to-glTF converter that allows us to drag and drop a COLLADA model and its textures to produce a glTF model for use in Cesium. This blog post is a series of tips for authoring 3D models and then exporting them to COLLADA to get the best performance and robustness.
The Khronos Group will be at SIGGRAPH Asia this coming weekend. Neil Trevett, Khronos Group President and VP of Mobile Content at NVIDIA will be speaking. There will be a panel session "Next Frontiers For Interactive Applications" on Saturday followed by a tech-talk "What's Next In Graphics APIs?" on Saturday December 6th which will cover the rapidly changing landscape of acceleration APIs for mobile devices and the Next Generation OpenGL Initiative first revealed at SIGGRAPH 2014.
Organized by The Immersive Technology Alliance, the Immersed conference features two days of sessions by worldwide virtual reality (VR), augmented reality (AR), and 3D experts. Some of the international speakers include John Gaeta (The Matrix Trilogy Academy Award winner, Lucasfilm), Mary Spio (Next Galaxy), Neil Trevett (The Khronos Group, Nvidia), Scott Broock (Jaunt), Shannon Blake Gans (New Deal Studios), Karl Krantz (Silicon Valley Virtual Reality), and more. Canada’s Habib Zargarpour (Creative Director, Microsoft Studios), Gord Harris (Christie Digital), David Nalasco (AMD), James Milward (Secret Location), Ana Serrano (Canadian Film Centre Media Lab), Ray Sharma (XMG Studio), James Stewart (Geneva Film Company), and more will also be speaking. Temporary code “ImmerseMe” reduces registration by $75. Deeply discounted exhibition options available for qualified early start-ups requiring media and investment group attention. Free exhibition opens to the general public on the Sunday afternoon. Limited space! Register for free online and in advance.
