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.
The annual Augmented Reality Conference hosted by Metaio - InsideAR - will be held in Munich, Germany on October 29-30th. Neil Trevett will be presenting on Bringing Spatial Awareness to Mobile AR including Google Project Tango and Advances in Mobile Sensing – and will provide insights on how Khronos APIs can be used to accelerate advanced AR applications. Metaio hosts InsideAR in Munich, Tokyo and Beijing, and had great success last year with more than 800 participants from industry, research, OEMs and developers.
NVIDIA has co-sponsored the WebGL Widget contest by contributing a new Shield Gaming Tablet as one of the prizes. This is in addition to two WebGL books Toni Parisi by sponsored by O’Reilly media; and the WebGL book by Sumeet Arora sponsored by Packt Publishing. Submit your best WebGL Widget by November 25 for a chance to win! We've recently increased the size limit from 30K to 200K. What can you create?
The COLLADA to glTF converter online tool allows you to convert your COLLADA models to glTF for use with Cesium. Simply drag-and-drop your COLLADA file (.dae) and any images it references by zipping them together. A self-contained glTF file will be downloaded once the conversion is finished, and a model preview will be shown below.
