Class

  • <DRM Primitive Geometry>

Superclass

Subclass

Definition

An instance of a concrete class derived from this DRM class specifies data to describe a <DRM Geometry Representation> instance.

Clarifications

1 A <DRM Primitive Geometry> instance contains a <DRM Union Of Primitive Geometry> instance as a component only when that <DRM Primitive Geometry> instance can be decomposed into nested <DRM Primitive Geometry> instances, as (for example) a <DRM Polygon> instance can be decomposed into subfaces.
