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.

Luxion KeyShot v5.1 is a conceptual design software that enables designers to import and enhance exisitng 3D models, creating variations for manufacturing, marketing or customer approval. KeyShots designers are able to import COLLADA files, as well as BIP, Alias WIRE, PTC Creo, Rhinoceros, SketchUp, SolidWorks, Solid Edge, Pro/ENGINEER, IGES, STEP, OBJ, 3ds, and FBX data. Users can paint, modify lighting, adjust the camera angle, edit and select background to create an image in real time using these imported models.
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.
CopperCube, the game engine focussing on WebGL has just been released in version 5. It now includes terrain support, video playback, network communication, iOS 8 WebGL support, shader programming, animation blending, and much more. There are also two new WebGL demos available on its website, showing it in action. A list of the new features with images is available as well.
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.
