Table 6.113—DRM_Geometry

Property

Description

Superclass

· <DRM SEDRIS Abstract Base>

Class

· <DRM Geometry>

Subclass

· <DRM Geometry Hierarchy>

· <DRM Primitive Geometry>

Definition

This is an abstract DRM class encapsulating both:

a) the concepts of traditional geometry and

b) measured data and organizational methods used to organize instances of these traditional geometry and of other concrete DRM classes within a transmittal.

Example(s)

· A <DRM Geometry Model Instance> of a polygonal <DRM Model> of a helicopter.

· A collection of polygons making up the graphical representation of a forest canopy.

· A <DRM Property Grid Hook Point>, connecting a <DRM Property Grid> of terrain elevation data from DTED to the geometry of an <DRM Environment Root>.
