QQuaternion

PyQt5.QtGui.QQuaternion

Description

The QQuaternion class represents a quaternion consisting of a vector and scalar.

Quaternions are used to represent rotations in 3D space, and consist of a 3D rotation axis specified by the x, y, and z coordinates, and a scalar representing the rotation angle.

Returns the length of the quaternion. This is also called the “norm”.

Returns the squared length of the quaternion.

normalize()

Normalizes the current quaternion in place. Nothing happens if this is a null quaternion or the length of the quaternion is very close to 1.

See also

length(), normalized().

---

normalized() → QQuaternion

Returns the normalized unit form of this quaternion.

If this quaternion is null, then a null quaternion is returned. If the length of the quaternion is very close to 1, then the quaternion will be returned as-is. Otherwise the normalized form of the quaternion of length 1 will be returned.

rotatedVector(QVector3D) → QVector3D

Rotates vector with this quaternion to produce a new vector in 3D space. The following code:

#     QVector3D result = q.rotatedVector(vector);

is equivalent to the following:

#     QVector3D result = (q * QQuaternion(0, vector) * q.conjugated()).vector();
