Class

• <DRM Strobing Light Behaviour>

Superclass

• <DRM Light Rendering Behaviour>

Subclass

• None.

Definition

An instance of this DRM class specifies that the aggregating DRM object appears to be a strobing light.

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.

Constraints

• Publishable object

Example(s)

• 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 6.334:

  

  Figure 6.334 — <DRM Strobing Light Behaviour> example

  Since the count of the <DRM Line> instance is greater than zero, it does not appear to be solid; each of its <DRM 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 <DRM Light Rendering Properties Control Link> instance is added. The lights strobe every two seconds.
