I have a setup with two stereo projection screens at 90 degrees to each other and head tracking for the camera.
I am trying to create a configuration fie but am uncertain as to which coordinate system is being used w.r.t. the screen postions. It says XLocal, YLocal and ZLocal, but does this mean it is in the coordiante system of the tracking system, or for Unity ? Also, is this the centre of the screen or one of the corners (I need to arrange the screens so that they meet at 90 degerees along one edge) ?
