What is a USD file?

USD (Universal Scene Description) is an open-source 3D scene format developed by Pixar Animation Studios. It describes complex 3D scenes with hierarchical composition, materials, lighting, and animation. USDZ is Apple's single-file variant — a ZIP archive containing a USD file plus textures — used for AR Quick Look on iPhone, iPad, and Apple Vision Pro. USD is rapidly becoming the industry standard for 3D content exchange across film, games, AR/VR, and e-commerce.
