glTF
glTF (GL Transmission Format) is an open-standard file format for 3D scenes and models, designed for efficient transmission and loading in real-time applications. It uses JSON for metadata and binary data for geometry, textures, and animations, making it a 'JPEG of 3D' for web and mobile platforms. The format is widely supported by engines like Unity, Unreal, and Three.js, enabling seamless 3D content integration.
Developers should learn glTF when working on web-based 3D applications, AR/VR projects, or games that require lightweight and fast-loading 3D assets, as it reduces file sizes and improves performance compared to formats like OBJ or FBX. It is essential for modern 3D web development using libraries like Three.js or Babylon.js, and for cross-platform compatibility in tools such as Blender or Sketchfab.
