BoundingBox

public BoundingBox(BoundingBox bb)

BoundingBox

public BoundingBox(javax.vecmath.Point3d[] atoms)

Constructs a BoundingBox by calculating maxs and mins of given array of atoms.

Parameters:

atoms - the atom array

Throws:

IllegalArgumentException - if atom array is empty

NullPointerException - if input is null

BoundingBox

public BoundingBox(BoundingBox[] boxes)

Given a set of bounding boxes returns a bounding box that bounds all of them.

Parameters:

boxes - an array of bounding boxes

Throws:

IllegalArgumentException - if input array is empty

NullPointerException - if input is null

Method Detail

getDimensions

public double[] getDimensions()

Returns the dimensions of this bounding box.

Returns:

a double array (x,y,z) with the dimensions of the box.

overlaps

public boolean overlaps(BoundingBox o,
                        double cutoff)

Returns true if this bounding box overlaps given one, i.e. they are within one cutoff distance in one of their 3 dimensions.

Parameters:

cutoff -

Returns:

contains

public boolean contains(javax.vecmath.Point3d atom)

Check if a given point falls within this box

Parameters:

atom -

Returns:

translate

getMinMax

public double[] getMinMax(double[] array)

Returns an array of size 2 with min and max values of given double array

Parameters:

array -

Returns:

toString

public String toString()

Overrides:

toString in class Object
