If you want complex scenes, animation, lights, and efficiency in distributing 3D models for use in a game engine or viewer, use the glTF format. This is especially ideal when you know exactly what tool will generate the glTF files and which tool will read the glTF files to ensure that they are fully compatible.
Which is better OBJ or glTF?
Compared to the OBJ file format, the glTF format provides a greater set of features. In addition to vertices, normals, basic materials, and texture coordinates that the OBJ file format does support, the glTF also supports: Hierarchical objects in the 3D scene structure.
What is glTF file used for?
GL Transmission Format (glTF) is an open-source and royalty-free 3D file that supports static models, animation, and moving scenes. glTF is used in games, native web applications, AR, VR, and 3D ads. You can also embed glTF files in documents like Microsoft Word or PowerPoint files.
