Method Detail

combine

public void combine(BoundingVolume parent,
                    BoundingVolume child)

Ensure that the parent bounds contains the child bounds entirely. It is assumed that the bounds are in the same coordinate system.

Parameters:

parent - The parent bound to expand to include this bounds

child - The child to make sure the parent contains

combine

public void combine(BoundingVolume parent,
                    float[] point)

Ensure that the parent bounds contains the child bounds entirely. It is assumed that the bounds are in the same coordinate system.

Parameters:

parent - The parent bound to expand to include this point

point - Coordinates of the point to make sure the bounds include

contain

public void contain(BoundingVolume parent,
                    BoundingVolume[] children)

Set the parent bounds to be the smallest container of the child bounds. The value of the containing bounds will be set to the minimal container.

Parameters:

parent - The bounds to set to contain the children

children - Listing of all the bounds to contain
