Definition |
An instance of this DRM class is a <DRM Light Source> instance that is considered to be located infinitely far away. It illuminates uniformly along a particular direction. Colour and control are inherited from the <DRM Light Source> class. A <DRM Infinite Light> instance has no bounds of influence and so affects all components of any <DRM Aggregate Geometry> instance that references it. |

Clarifications |
1A <DRM Classification Data> component, if present, allows a data provider to specify whether the <DRM Light Source> instance represents an environmental object, such as the sun. 2If a <DRM Light Source> instance is to be turned on and off dynamically, it has a <DRM Light Source Control Link> component to express that control mechanism. 3The <DRM Reference Vector> component specifies the direction of light source illumination and its vector_type = LIGHT_DIRECTION. |
