Class |
· <DRM Connected Geometry Edge> |

|
Definition |
An object of this class defines a topological relationship between a <DRM Geometry Node> and an ordered set of <DRM Geometry Edge>s, indicating that the <DRM Geometry Node> connects the <DRM Geometry Edge>s. |
||||||
|
Example(s) |
· Consider a <DRM Geometry Edge> representing part of the boundary of a <DRM Geometry Face>, which in turn represents a lake. The <DRM Geometry Edge> naturally contains two <DRM Geometry Edge Terminal Node>s, which in turn contain <DRM Geometry Node>s. In order to supply clean, high-level topological information, the data provider gives each of these <DRM Geometry Node>s a <DRM Connected Geometry Edge> component, which relates it back to the <DRM Geometry Edge> of which it is a part. This allows a consumer, encountering one of the <DRM Geometry Node>s, to determine what edges it participates in. |
