  org.apache.commons.math3.geometry.euclidean.threed.AbstractEllipse
      org.apache.commons.math3.geometry.euclidean.threed.Disk

All Implemented Interfaces:

Serializable, Shape, SolidShape

public final class Disk
extends AbstractEllipse
implements Serializable

Implements a representation of a disk.

The disk is defined by a center, a normal to the plane containing the disk, and a radius.
This class implements the SolidShape interface.

Use sample :

// normal to the disk
final Vector3D normPlane = new Vector3D(...);
// center of the disk
final Vector3D centerDisk = new Vector3D(...);
// Radius of the disk
final double diskRadius = 6.55957;
// We create the disk
final Disk myDisk = new Disk(centerDisk, normPlane, diskRadius);
final double rez = capDisk.distanceTo(something);
