Clarifications

¹This <DRM Geometry Node> instance corresponds to the <DRM Location 3D> component of the <DRM Volume Object> instance.

²A <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 A <DRM Polygon> instance can be decomposed into multiple <DRM Polygon> instances representing subfaces.

³The <DRM Location 3D> component specifies the centre of the volume specified by the <DRM Volume Extent> component.

Example(s)

A <DRM Volume Object> instance represents a column of a building by specifying a cylindrical shape.
