Clarifications

1A <DRM Primitive Geometry> instance P has a <DRM Union Of Primitive Geometry> component only when P can be decomposed into nested <DRM Primitive Geometry> instances.

Example(s)

  • A geometric representation of a treeline, or a string of lights that follow the path of the <DRM Arc> instance.
