getDistance

public double getDistance(Point3D point)

Description copied from interface: Shape3D

Gets the distance of the shape to the given point, or the distance of point to the frontier of the shape in the case of a plain shape.

Specified by:

getDistance in interface Shape3D

contains

public boolean contains(Point3D point)

A point 'contains' another point if their euclidean distance is less than the accuracy.

Specified by:

contains in interface Shape3D

isEmpty

public boolean isEmpty()

Specified by:

isEmpty in interface Shape3D

isBounded

public boolean isBounded()

Description copied from interface: Shape3D

Returns true if the shape is bounded, that is if we can draw a finite rectangle enclosing the shape. For example, a straight line or a parabola are not bounded.

Specified by:

isBounded in interface Shape3D

getBoundingBox

public Box3D getBoundingBox()

Specified by:

getBoundingBox in interface Shape3D

clip

public Shape3D clip(Box3D box)

Specified by:

clip in interface Shape3D

transform

public Point3D transform(AffineTransform3D trans)

Specified by:

transform in interface Shape3D

equals

public boolean equals(Object obj)

Overrides:

equals in class Object
