Table 6.190—DRM_Parallelepiped_Volume_Extent

Property

Description

Superclass

· <DRM Volume Extent>

Class

· <DRM Parallelepiped Volume Extent>

Subclass

· none

Definition

An object of this DRM class specifies the length and directions of the edges of a parallelepiped volume relative to an unspecified location for the volume center.

Example(s)

· A <DRM Bounding Volume> for a building will have a <DRM Parallelepiped Volume Extent> with:
      1^st edge_length = width, first <DRM Reference Vector> points to the right,
      2^nd edge_length = depth, second <DRM Reference Vector> points to the back, and
      3^rd edge_length = height, third <DRM Reference Vector> points up.
