Chapter 1 — Introduction to OpenUSD and Scene Description
OpenUSD (Open Universal Scene Description) is a framework and file format used to describe complex 3D scenes. It allows applications to represent objects, geometry, materials, lighting, and relationships within a structured scene graph. OpenUSD is widely used in animation, visual effects, simulation, and increasingly in real-time 3D applications.
Example: Minimal OpenUSD file
