Example

1. Consider a representation of the sun in a game set in the outer solar system. The data provider in this transmittal has chosen to represent the sun as a <Point> instance with a <Light Rendering Properties> component.

2. Consider a <Model> instance J representing a jeep. J has a <Geometry Model> component, which in turn has a <LOD Related Geometry> component L with lod_data_type = SE_LODDATTYP_DISTANCE. The branch of L representing the jeep as viewed from a kilometre away represents a headlight as a <Point> instance having a <Light Rendering Properties> component.
