Class Quaternion_F64

All Implemented Interfaces:

public class Quaternion_F64 extends Object implements Serializable

Specifies a 3D rotation using a quaternion. q = w + x*i + y*j + z*k, where (w,x,y,z) are the parameters of the quaternion and (i,j,k) are unit vectors representing the Cartesian axis.

If the quaternion is a unit quaternion then the following is true:
q = cos(theta/2) + (x*i + y*j + z*k)*sin(theta/2)
where 'theta' is the angle of rotation, (x,y,z) is the unit axis of rotation.
