What is the meaning of the matrix #4

Hi Alex, coming from the vive-diy-position-sensor project. I am trying to understand what are those outputted parameters.

For example: " b0 origin -1.528176 2.433746 -1.969393 matrix -0.839498 0.340747 -0.423244 -0.041220 0.736752 0.674906 0.541798 0.584028 -0.604456"

is base station 0, originated at location -1.5... 2.4... -1.9.... (x,y,z I supposed). What I don't have a clue is the matrix, what are those numbers for?

Thanks

It's a 3d rotation matrix of the base station, see https://en.wikipedia.org/wiki/Rotation_matrix

I see. I guess i have to have the VR headset to do the job? I am going to ask around for one.

Thanks Alex!
