Quaternion
(w, x, y, z)[source]¶ Bases:
object
Class to represent a 4D Quaternion.
Parameters: - w (float) – Real value of Quaternion
- x (float) – x coordinate of Quaternion
- y (float) – y coordinate of Quaternion
- z (float) – z coordinate of Quaternion
-
static
Euler
(vector)[source]¶ Create a quaternion using Euler rotations.
Parameters: vector (Vector3) – Euler rotations Returns: Generated quaternion Return type: Quaternion
-
static
FromAxis
(angle, a)[source]¶ Create a quaternion from an angle and an axis.
Parameters: - angle (float) – Angle to rotate
- a (Vector3) – Axis to rotate about
-
angleAxisPair
¶ Gets or sets the angle and axis pair.
Notes
When getting, it returns a tuple in the form of
(angle, x, y, z)
. When setting, assign likeq.eulerAngles = (angle, vector)
.
-
conjugate
¶ The conjugate of a unit quaternion
-
copy
()[source]¶ Deep copy of the Quaternion.
Returns: A deep copy Return type: Quaternion
-
eulerAngles
¶ Gets or sets the Euler Angles of the quaternion
-
normalized
()[source]¶ A normalized Quaternion, for rotations. If the length is 0, then the identity quaternion is returned.
Returns: A unit quaternion Return type: Quaternion
