Quaternion

public Quaternion()

Quaternion

public Quaternion(Real x,
                  Real y,
                  Real z,
                  Real w)

Constructs a new Quaternion with the given W/X/Y/Z coordinates.

Parameters:

w - the W coordinate.

x - the X coordinate.

y - the Y coordinate.

z - the Z coordinate.

Quaternion

public Quaternion(Real[] vec)

Constructs a new Quaternion with the given W/X/Y/Z coordinates.

Parameters:

vec - the coordinates in an array.

Quaternion

public Quaternion(Vector v,
                  Real w)

Quaternion

public Quaternion(java.lang.String s)

Constructs a new Quaternion by parsing the given String. This uses the MathUtil class to parse Real objects for the coordinates in a type-neutral manner.

Parameters:

s - the String to parse.
