sgLightObject Class Reference

#include <sgLightObject.h>

Inheritance diagram for sgLightObject:

Detailed Description

This class extends fxLight to provide mission level static light objects.

These light objects can also be used as dynamic lights and linked to mission level particle emitters for coordinated particle system light sources (flickering,...).
