Class

• <DRM Strobing Light Behaviour>

Superclass

• <DRM Light Rendering Behaviour>

Subclass

• None.

Definition

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

The period field specifies in seconds the total period of time (both on and off).

The delay field specifies in seconds the initial delay before the light is illuminated, and is better characterized as a pre-start; it 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. It is most efficiently represented as shown in Figure 6.317.

  

  Figure 6.317 — <DRM Strobing Light Behaviour> example

  Since the <DRM Line> instance’s count 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 will always be on, unless a <DRM Light Rendering Properties Control Link> instance is added. The lights strobe every two seconds.
