Regarding the MotionFX Library. In what order is the quaternion given??

[VNava.1]

Hi, my name is Vincenzo,

I'm studying the MotionFX library and I want to understand In what order the quaternion is given by the MotionFX library.

Reading the manual, I know that the MotionFX can compute:

rotation, quaternions, gravity and linear acceleration data.

Regarding the quaternion, I don't understand how the elements are ordered. It is an array with 4 elements: qw,qx,qy,qz (q0,q1,q2,q3). I suppose that it is the order, but can someone confirm it?

Thank you in advance!

Hi Vincenzo,

In MotionFX library the q0, q1, q2, q3 is in qx, qy, qz, qw order.
