java.lang.Object
  com.brackeen.javagamebook.math3D.Rectangle3D

All Implemented Interfaces:

Transformable

public class Rectangle3D

extends java.lang.Object

implements Transformable

A Rectangle3D is a rectangle in 3D space, defined as an origin and vectors pointing in the directions of the base (width) and side (height).

Constructor Summary

Rectangle3D()
Creates a rectangle at the origin with a width and height of zero.

Rectangle3D(Vector3D origin, Vector3D directionU, Vector3D directionV, float width, float height)
Creates a new Rectangle3D with the specified origin, direction of the base (directionU) and direction of the side (directionV).
