All Implemented Interfaces:

Serializable, Cloneable

public class DirectionalLight
extends ChartNode3D
implements Serializable

A directional light.

A directional light is an oriented light with an origin at infinity. The direction is defined by the attribute "Direction".

The light's position is in a coordinate system in which the default viewport is the cube [-1,1] by [-1,1] by [-1,1].

Constructor Detail

DirectionalLight

public DirectionalLight(Chart3D parent)

Creates a directional light pointing in the negative z direction.

Parameters:

parent - is the Chart3D parent of this node.

DirectionalLight

public DirectionalLight(Chart3D parent,
                        double x,
                        double y,
                        double z)

Creates a directional light pointing with a specified direction.

Parameters:

parent - is the Chart3D parent of this node.

x - is the x-component of the direction vector.

y - is the y-component of the direction vector.

z - is the z-component of the direction vector.

Method Detail

addToSceneGraph

protected void addToSceneGraph(Group parent)

Description copied from class: ChartNode3D

Called to add this object to the scene graph.

Specified by:

addToSceneGraph in class ChartNode3D

Parameters:

parent - is the node in the scene graph at which this object is to be added.

getDirection

public Vector3f getDirection()

Returns the value of the "Direction" attribute.

Returns:

The Vector3f value of the "Direction" attribute, if defined. Otherwise, (0, 0, -1) is returned.

setDirection

public void setDirection(double x,
                         double y,
                         double z)

Sets the value of the "Direction" attribute to a light direction.

Parameters:

x - is the x-component of the direction vector.

y - is the y-component of the direction vector.

z - is the z-component of the direction vector.

setDirection

public void setDirection(Vector3f direction)

Sets the value of the "Direction" attribute to a light direction.

Parameters:

direction - Vector3f direction.
