Constructor Detail

MutableVector3D

public MutableVector3D()

Construct a MutableVector3D and initialise it to (0, 0, 0).

MutableVector3D

public MutableVector3D(double new_x,
                       double new_y,
                       double new_z)

Construct a MutableVector3D and initialise it to (new_x, new_y, new_z).

Parameters:

new_x - x component

new_y - y component

new_z - z component

MutableVector3D

public MutableVector3D(Vector3D v)

Construct a MutableVector3D equal to v.

Parameters:

v - the vector to copy from

MutableVector3D

public MutableVector3D(java.lang.String s)
                throws java.text.ParseException

Construct a new MutableVector3D by parsing a string. Parses the String s for a Vector3D given in the form (x, y, z) where x, y and z are doubles. All whitespace is stripped and "0" is recognised to mean the zero vector (0, 0, 0).

Parameters:

s - the string to parse

Throws:

java.text.ParseException - if there was an error parsing the string

Method Detail

setX

public void setX(double new_x)

Set the x component of this Vector3D

Parameters:

new_x - x component

setY

public void setY(double new_y)

Set the y component of this Vector3D

Parameters:

new_y - y component

setZ

public void setZ(double new_z)

Set the z component of this Vector3D

Parameters:

new_z - z component

multScalarInplace

public void multScalarInplace(double d)

Multiply each component of this Vector3D by the scalar d inplace.

addInplace

public void addInplace(Vector3D v)

Increment this Vector3D by the Vector3D v inplace.

subtractInplace

public void subtractInplace(Vector3D v)

Decrement this Vector3D by the Vector3D v inplace.
