Definition

This is an abstract DRM class that specifies a conceptual abstraction of the standard topological elements - <DRM Geometry Node>s, <DRM Geometry Edge>s, and <DRM Geometry Face>s.

Example(s)

·         The interrelationship between points, lines, areas and volumes as in a depiction of a chain of mountains.
