The three elements of the rotation vector are - * <x*sin(theta/2), y*sin(theta/2), z*sin(theta/2)>, such that the magnitude of the rotation + * <x, y, z>. The three elements of the rotation vector are + * <x*sin(theta/2), y*sin(theta/2), z*sin(theta/2)>, such that the magnitude of the rotation * vector is equal to sin(theta/2), and the direction of the rotation vector is equal to the * direction of the axis of rotation. The three elements of the rotation vector are equal to * the last three components of a unit quaternion - * <cos(theta/2), x*sin(theta/2), y*sin(theta/2), z*sin(theta/2)>.
