plane_XYZ coordinate system

[D4vx]

Hi, firstly would like to thank you and all contributors working on this code base - its a very interesting piece of work.

I have extracted the plane_XYZ data from the inference method and wanted to know if the resultant data is indeed stored as X,Y,Z?

i.e.
[[-1.2226353 2.188383 -0.90884477]
[-1.2185622 2.1879408 -0.9086611 ]
[-1.214491 2.187499 -0.90847766]
...
[ 1.0764412 1.9388486 -0.8052121 ]
[ 1.0796382 1.9385015 -0.8050679 ]
[ 1.0828342 1.9381547 -0.8049239 ]]

[[-1.2199904 2.183649 -0.91069716]
[-1.215927 2.1832092 -0.9105137 ]
[-1.2118648 2.182769 -0.9103302 ]
...
[ 1.0743777 1.9351318 -0.8070523 ]
[ 1.0775691 1.9347862 -0.8069082 ]
[ 1.0807592 1.9344406 -0.80676407]]

[[-1.217357 2.1789358 -0.9125416 ]
[-1.213303 2.1784978 -0.91235816]
[-1.2092502 2.1780596 -0.91217464]
...
[ 1.0723221 1.9314294 -0.8088856 ]
[ 1.0755078 1.9310851 -0.8087414 ]
[ 1.0786922 1.9307408 -0.8085972 ]]]

I ask because the frame of reference provided in the predecessor repo (PlaneNet) refers to the following:

The plane equation is in the camera frame, where x points to the right, y points to the front, and z points to the up.
PlaneNet - Plane Representation

Is the data actually stored as X,Y,Z and should be interpreted as such? or do I need to read it as X,Z,Y?

Sorry if this appears an obvious question - I am fairly new to this discipline of machine learning and visual interpretation.

Thanks
