public class Quat

extends javax.vecmath.Quat4f

A class for dealing with quaternions based on the java3d quat4d class.

Note: Flock of birds quaternions come in the following order:
w x y z;

while this class may expect arguments in this order:
x y z w.

Method Detail

transformq0Toq1

public static Quat transformq0Toq1(Quat q0,
                                   Quat q1)

Calculates the transformation that would take this quaternion (q0)to the given quaternion (q1).

Defined as q = q0* x q1
where q0* is the inverse of q0

Returns:

a Quat representing the transform

getAxisAngle

public void getAxisAngle(float[] aa)

Calculates the axis-angle representation of this rotation, and copies the value into aa. The format will be x y z a where a is in radians

Parameters:

aa - the float[4] that the axis-angle value will be copied in to.
