Class Point

java.lang.Object
  org.jzy3d.plot3d.primitives.AbstractDrawable
      org.jzy3d.plot3d.primitives.Point

All Implemented Interfaces:

ISingleColorable, IGLRenderer, ISortableDraw

Direct Known Subclasses:

PickablePoint

public class Point
extends AbstractDrawable
implements ISingleColorable

A Point3d is a storage for a Coord3d and a Color that represents a drawable 3d point.
The Point3d is used for:

• adding a Point3d to a Graph.
• providing to other primitives (e.g. Polygon) a way to associate a coordinate and a color.

A Point3d is defined by the following methods:

• setData() defines the point's position
• setColor() defines the point's color
• setWidth() defines the point's width
