Class Point3D

java.lang.Object
org.jfree.chart3d.graphics3d.Point3D
All Implemented Interfaces:
Serializable
public final class Point3D extends Object implements Serializable
A point in 3D space (this class is also used to represent vectors in 3D space). Instances of this class are immutable.

NOTE: This class is serializable, but the serialization format is subject to change in future releases and should not be relied upon for persisting instances of this class.
