Class

• <DRM Ambient Colour>

Superclass

• <DRM SEDRIS Abstract Base>

Subclass

• None.

Definition

An instance of this DRM class specifies the ambient reflectance component of a <DRM Primitive Colour> or <DRM Light Source>, providing the base colour to the lighting equation for the object being lit or the light itself, respectively.

Ambient light is the result of bouncing light rays around the environment until the light has been diffused so much that its source and direction cannot be determined. Consequently, <DRM Ambient Colour> is

• independent of the angle of the lit object to the light source
• independent of the angle of the lit object to the observer

The <DRM Ambient Colour> of an object is combined with the ambient component of each incoming light source to determine the colour due to the ambient light.
