+efficient transmission and loading of 3D scenes and models by applications.
+glTF minimizes both the size of 3D assets, and the runtime processing needed
+to unpack and use those assets. glTF defines an extensible, common publishing
+format for 3D content tools and services that streamlines authoring workflows
+and enables interoperable use of content across the industry.")
