Clarifications

1 A <DRM Geometry Node> associated with a <DRM Point> instance represents the topology of that <DRM Point>.

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

Example(s)

  • The abstract representation of the sun, a <DRM Point> in space from which the light emanates.

  • The headlight of a jeep as viewed from a kilometre away.
