GLTFLoader

GLTFLoader is a JavaScript library used for loading and parsing glTF (GL Transmission Format) files within web applications. glTF is a modern, efficient, and extensible format for transmitting 3D scenes and models, designed to be compact and performant for real-time rendering. GLTFLoader plays a crucial role in enabling the display of 3D content on the web, often in conjunction with rendering libraries like Three.js or Babylon.js.

The primary function of GLTFLoader is to take a glTF file, which can be in JSON format or a binary `.glb` format, and convert its data into a usable 3D scene representation that can be manipulated and rendered by a graphics engine. This process involves parsing the JSON or binary data, loading associated assets such as textures, and constructing the 3D objects, materials, animations, and scene graph.

Key features of GLTFLoader typically include support for various glTF extensions, animation playback, scene hierarchy management, and efficient handling of textures and geometry. By abstracting away the complexities of the glTF specification, GLTFLoader simplifies the integration of 3D models into web experiences, making it a popular choice for developers working with 3D graphics in browsers. Its implementation is often found within popular 3D frameworks, providing a standardized way to incorporate glTF assets.
