public class BoundingBox3
extends Object
implements Cloneable, Copyable

3D bounding box This implements a three-dimensional rectangular box with sides parallel to the coordinate planes. This is intended to be used to compute "bounding boxes" of geometry but could be used more generally. If the x dimension of the bounding box's size is < 0, the bounding box is considered to be "undefined"; this is what the bounding box of the empty set is. This differs from a zero-size bounding box, which is the bounding box of a point. Undefined behavior will result if the x dimension of the bounding box's size is >= 0 and the y or z dimensions of the bounding box's size are < 0.

BoundingBox3(): Create a new undefined bounding box.
BoundingBox3(BoundingBox3): Create a new bounding box identical to the specified one.
BoundingBox3(Point3, Vector3): Create a new bounding box with a specified center and size.

BoundingBox3

  public BoundingBox3()

Create a new undefined bounding box.

BoundingBox3

  public BoundingBox3(BoundingBox3 copy)

Create a new bounding box identical to the specified one.

BoundingBox3

  public BoundingBox3(Point3 center,
                      Vector3 size)

Create a new bounding box with a specified center and size. The size is the full width, height, and depth of the box. Internally, however, the "half-size" (half of each dimension) is stored, and this is what can be retrieved (using getHalfSize()).

clear

  public void clear()

getCenter

  public final synchronized Point3 getCenter()

Return the center of the bounding box. This Point3 is owned by the BoundingBox3; don't modify it.

getHalfSize

  public final synchronized Vector3 getHalfSize()

Return the half-size of the bounding box. This Vector3 is owned by the BoundingBox3; don't modify it.

setValue

  public final void setValue(Point3 center,
                             Vector3 size)

Set the center and size of the bounding box.

setValue

  public final void setValue(Point3 leftBottomBack,
                             Point3 rightTopFront)

Set the value of the bounding box to be just large enough to include the points leftBottomBack and rightTopFront. Each component of the point leftBottomBack must be less than or equal to the corresponding component of rightTopFront.

setCenter

  public final void setCenter(Point3 center)

Set the center of the bounding box.

setCenter

  public final void setCenter(float x,
                              float y,
                              float z)

Set the center of the bounding box

setSize

  public final synchronized void setSize(Vector3 size)

Set the size of the bounding box

setSize

  public final synchronized void setSize(float x,
                                         float y,
                                         float z)

Set the size of the bounding box

setHalfSize

  public final synchronized void setHalfSize(Vector3 size)

Set the size of the bounding box by specifying a half-size.

setHalfSize

  public final synchronized void setHalfSize(float x,
                                             float y,
                                             float z)

Set the size of the bounding box by specifying a half-size.

zeroSize

  public final synchronized void zeroSize()

Set the bounding box to have zero size.

infiniteSize

  public final synchronized void infiniteSize()

Set the bounding box to have infinite size.

undefined

  public final synchronized void undefined()

Set the bounding box to be undefined.

union

  public void union(BoundingBox3 b)

Compute the smallest bounding box which contains this and b

include

  public void include(Point3 p)

If p does not lie inside the bounding box, recompute the bounding box to be the smallest box containing the original box and the point p.

include

  public void include(float x,
                      float y,
                      float z)

If (x, y, z) does not lie inside the bounding box, recompute the bounding box to be the smallest box containing the original box and the point p.

inside

  public boolean inside(float x,
                        float y,
                        float z)

Return true if the point (x, y, z) lies inside of the bounding box.

inside

  public boolean inside(Point3 p)

Return true if the point p lies inside of the bounding box.

transform

  public void transform(Matrix4 m)

rayIntersection

  public float rayIntersection(Ray3 ray)

Returns the distance (scaled by the magnitude of the ray direction vector) from the ray origin to a bounding box. If the ray origin is inside or on the bounding box, the distance returned will be zero. A negative return value indicates that the ray does not intersect the bounding box.

copy

  public void copy(Copyable cop)

clone

  public Object clone()

Overrides:: clone in class Object

equals

  public boolean equals(BoundingBox3 b)

toString

  public String toString()

Overrides:: toString in class Object
