![]() Based on a proposal by Fraunhofer originally presented at SIGGRAPH 2016, Physically based rendering (PBR) was added, replacing WebGL shaders used in glTF 1.0. The second version, glTF 2.0, was released in June 2017, and is a complete overhaul of the file format from version 1.0, with most tools adopting the 2.0 version. In October 2016, Microsoft joined the 3D Formats working group at Khronos to collaborate on glTF. Adoption of glTF 1.0 Īt SIGGRAPH 2016, Oculus announced their adoption of glTF citing the similarities to their ovrscene format. On October 19, 2015, the glTF 1.0 specification was released. At SIGGRAPH 2012, Khronos presented a demo of glTF, which was then called WebGL Transmissions Format (WebGL TF). The file format was conceived in 2012 by members of the COLLADA working group. As such, its creators have described it as the " JPEG of 3D." Releases glTF 1.0 ![]() It is intended to be a streamlined, interoperable format for the delivery of 3D assets, while minimizing file size and runtime processing by apps. ![]() An open standard developed and maintained by the Khronos Group, it supports 3D model geometry, appearance, scene graph hierarchy, and animation. Alternatively, both formats may be self-contained by directly embedding binary data buffers (as base64-encoded strings in. glb files may reference external binary and texture resources. A glTF file uses one of two possible file extensions. GlTF is a standard file format for three-dimensional scenes and models.
