gutz::Light Class Reference

#include <Light.h>

Inheritance diagram for gutz::Light:

List of all members.

Detailed Description

A Light interaction class.

A Light interaction class. Handles basic operations relating to light placement. Be sure to keep the clipping planes and screen size current. This class is a child of Camera, so interaction is identical to the cameras
