All Implemented Interfaces:

Serializable, Cloneable

public class PointLight
extends ChartNode3D
implements Serializable

A point light source.

A point light source is at a fixed point in space and radiates light equally in all directions away from the light source. The light's position is defined by the attribute "Position".

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

PointLight

public PointLight(Chart3D parent)

Creates a point light source at the origin.

Parameters:

parent - is the Chart3D parent of this node.

PointLight

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

Creates a point light at a specified position.

Parameters:

parent - is the Chart3D parent of this node.

x - is the x-component of the position.

y - is the y-component of the position.

z - is the z-component of the position.

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.

getPosition

public Point3f getPosition()

Returns the value of the "Position" attribute.

Returns:

The Point3f value of the "Position" attribute, if defined. Otherwise, (0, 0, 0) is returned.

setPosition

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

Sets the value of the "Point" attribute to a light point.

setPosition

public void setPosition(Point3f position)

Sets the value of the "Point" attribute to a light point.

Parameters:

position - is the location of the light.
