Changing the optitrack axes

[ankitvora23]

Hi,

I understand that the Optitrack coordinate system by default is oriented as if the Y axis is pointed up and X and Z axes lie on the ground. Is there a way i could change these to get Z axis pointing upwards and X and Y lying on the ground ? I couldn't find any such transformation.
What I did find was to transform my rigid body frame but that is not what I essentially want.

Thanks,
Ankit

Hello ankitvora23,

Thank you for reaching out to the community regarding the Motive coordinate system.

Currently, it is not possible to change the axes in Motive. It is possible, however, to change the up axis in the realtime data stream if you are streaming data out of Motive. To do this, you can simply change the Up Axis in the Advanced Network Options. This can be found in the Streaming Pane.

It is also possible to place your Calibration Square in a different way in order to change the axes in Motive, but since Motive remains Y-Up, this means all 3D data will display sideways in Motive itself.
