z#
- Quaternion.z#
Third element of the vector part of the Quaternion.
Given a quaternion \(\mathbf{q}=\begin{pmatrix}q_w & \mathbf{q}_v\end{pmatrix} = \begin{pmatrix}q_w & q_x & q_y & q_z\end{pmatrix}\), the third element of the vector part is \(q_z\).
- Returns:
q_z – Third element of vector part of the quaternion.
- Return type:
float
Examples
>>> q = Quaternion([2.0, -3.0, 4.0, -5.0]) >>> q.view() Quaternion([ 0.27216553, -0.40824829, 0.54433105, -0.68041382]) >>> q.z -0.6804138174397717
It can also be accessed directly, treating the Quaternion as an array:
>>> q[3] -0.6804138174397717
