Khronos Finalizes glTF 1.0 Specification


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.

glTF Tips for Artists

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.
