All Implemented Interfaces:

java.io.Serializable

public class SimpleLightNode

extends Node

Started Date: Jul 21, 2004

SimpleLightNode defines a scene node that contains and maintains a light object. A light node contains a single light, and positions the light based on it's translation vector. If the contained light is a spot light, the rotation of the node determines it's direction. If the contained light is a Directional light rotation determines it's direction. It has no concept of location.

Constructor Detail

SimpleLightNode

public SimpleLightNode(java.lang.String name,
                       Light light)

Constructor creates a new LightState object. The light state the node controls is required at construction time.

Parameters:

name - the name of the scene element. This is required for identification and comparision purposes.

light - The light to be moved around by this Node

Method Detail

updateWorldData

public void updateWorldData(float time)

updateWorldData modifies the light data based on any change the light node has made.

Overrides:

updateWorldData in class Node

Parameters:

time - the time between frames.
