Description

Class

  • <DRM Geometry Node>

Superclass

Subclass

  • None.

Definition

An instance of this DRM class is a zero-dimensional <DRM Geometry Topology> instance specifying the topological location of various geometry representations and/or an endpoint of one or more <DRM Geometry Edge> instances.

The location of a <DRM Geometry Node> instance is the same as that of the spatially located DRM object of which the node is a component.

Clarifications

1The <DRM Geometry Node> instance corresponds to the <DRM Location> instance representing the centre of each <DRM Ellipse> instance.

2The other half of this relationship is supplied by the <DRM Geometry Edge> component of the <DRM Geometry Node> instance.

3This is the <DRM Geometry Face> instance that contains the <DRM Geometry Node> instance, if one exists.

4This is the <DRM Geometry Volume> instance that contains the <DRM Geometry Node> instance, if any.

5The <DRM Geometry Node> instance corresponds to the <DRM Location> instance representing the centre of each <DRM Volume Object> instance.
