Superclass

· <DRM Geometry Hierarchy>

Class

· <DRM Property Grid Hook Point>

Subclass

· none

Definition

This DRM class represents a kind of <DRM Geometry Hierarchy>. A <DRM Property Grid Hook Point> is used to "instance" a <DRM Property Grid> into the world geometry. In particular, the origin of the spatial axes of a component <DRM Property Grid> is located at the <DRM Property Grid Hook Point> component <DRM Location>.

Since the <DRM Property Grid Hook Point> separates the <DRM Property Grid> data from the <DRM Location>, <DRM Property Grid> data can be reused by several <DRM Property Grid Hook Point>s.

Example(s)

· A one-dimensional <DRM Property Grid> of type OCEAN_FLOOR BATHYMETRY contains a depth axis only. The <DRM Property Grid Hook Point> <DRM Location> serves to position this grid ithe currently scoped 'world' spatial reference frame.

· A two-dimensional <DRM Property Grid> of type TERRAIN ELEVATION contains elevation relative to the southwest corner of the grid. The <DRM Property Grid Hook Point> <DRM Location> serves to position this grid corner into the three-dimensional world.
