Chapter 1 — Introduction to OpenUSD and Scene Description
OpenUSD organizes data using a scene graph, where objects are arranged in a hierarchical structure. Each node represents an element in the scene such as a transform, geometry, camera, or light.
Example: Scene hierarchy
#usda 1.0
def Xform "World"
{
def Xform "Car"
{
def Xform "Wheel_FL" {}
def Xform "Wheel_FR" {}
}
}The car object contains two wheel objects as children.
