QQuaternion convert euler angle to quaternion not work

[WuYaZi]

below is my code:

QQuaternion quat;
quat.fromEulerAngles(0, 0, thea);


orix = quat.toVector4D().x();
oriy = quat.toVector4D().y();
oriz = quat.toVector4D().z();
oriw = quat.toVector4D().w();

every time when i change thea , orix-oriw never changes, i wonder weather this is a bug? my qt version is 5.15.2.
and when i test my data on https://quaternions.online/,it has no problem.

Hi,

@WuYaZi said in QQuaternion convert euler angle to quaternion not work:

QQuaternion quat;
quat.fromEulerAngles(0, 0, thea);

There's no bug. You're not using the method correctly. It's a static method.

QQuaternion quat = QQuaternion::fromEulerAngles(0, 0, thea);

thks, i mixed qquaternion with eigen library.
