Class Name: Strobing Light Behaviour
Subclasses
This DRM class is concrete and has no subclasses.
Definition
An instance of this DRM class specifies that the aggregating DRM object
appears to be a strobing light.

This class appears on only one page of the DRM class diagram.
Example
Consider a model of an airport, in which the data provider wishes
to place a strobing light string along a runway. The light emitted
is negligible at an ordinary viewing range, as depicted in
Figure 6.69:
Figure 69 — <DRM Strobing Light Behaviour> example
Since the count of the <Line> instance
is greater than zero, it does not appear to be solid; each of its
<Vertex> components is shown independently. The
light_diameter
in pixels is not applicable, and the light
is visible at any distance since no extingishing range is
specified. The runway lights are always on, unless a
<Light Rendering Properties Control Link>
instance is added. The lights strobe every two seconds.

Notes
Fields Notes
The period field specifies, in seconds,
the total period of time both on and off where on duration and
off duration are equal.
The delay field specifies, in seconds,
the initial delay before the strobing behaviour is to begin.
A separate delay for each light allows a series of lights to
appear asynchronous.
