Class Name: Geometry Node
Subclasses
This DRM class is concrete and has no subclasses.
Definition
An instance of this DRM class is a zero-dimensional
<Geometry Topology> instance
specifying the topological location of various geometry representations
and/or an endpoint of one or more <Geometry Edge> instances.
The location of a
<Geometry Node> instance is the same as that
of the spatially located <Geometry Representation> instance
or <Vertex> instance to which the node is associated. If the
<Geometry Node> instance is associated to more than one such
DRM object, the DRM objects shall be collocated.

Example
The endpoints of a <Geometry Edge> instance
representing part of the lighting of a runway are specified by
<Geometry Node> instances.

Notes

The <Geometry Node> instance
corresponds to the <Location> instance
representing the centre of each <Ellipse>
instance.
This relationship indicates the collection of
<Geometry Edge> instances that are bounded by the
<Geometry Node> instance, if any. For each
<Geometry Edge> instance associated with the
<Geometry Node> instance through the use of
an <Edge Direction> link object with
a forwards field value of
SE_TRUE, the <Geometry Node> instance
is the starting node of the <Geometry Edge> instance. For
each <Geometry Edge> instance associated with the
<Geometry Node> instance through the use of
an <Edge Direction> link object with
a forwards field value of
SE_FALSE, the <Geometry Node> instance
is the ending node of the <Geometry Edge> instance.
This is the <Geometry Face> instance that
contains the <Geometry Node> instance,
if one exists.
This is the <Geometry Volume> instance that
contains the <Geometry Node> instance,
if any.
The <Geometry Node> instance
corresponds to the <Location> instance
representing the centre of each
<Volume Object> instance.
