Typically we assume that the tracking is in meters and so is also the assumption in the document. You could either apply a transform on the tracker (scale) or on the scene. You can apply a tracker transform on the <VRPNConnection> tag <Tracker id="0" name="something"> <TrackerTransform value=" 1 0 0 0 0 1 0 0 0 0 1 0 0 0 0 1"> -nikhil > Thanks a lot for your input, it's much appreciated. > > Seán > > ------------ PVX file --------------- > > <?xml version="1.0" ?> > <pvx> > <Process Type="client" /> > <Process Type="server"> > <EyeSeparation Value="65"/> > <Machine name="hubble1" > Environment="DISPLAY=:0" > LowerLeft="-1560, 0, 480" > LowerRight="500, 0, 480" > UpperRight="500, 0, 1940"> > </Machine> > </Process> > </pvx> > >
