Getting Started
Measure the XY and Z distance from the centre of the TrackPod head to
the central stagemark following the convention shown in Figure 6:
• At the central stagemark the X, Y and Z are zero.
• X is the stage width, with positive values towards stage left and
negative values towards stage right.
• Y is the stage depth, with positive values towards upstage and negative
values towards downstage.
• Z is the stage height, with positive values above the stage floor.
Once you have measured the location of the TrackPod you must enter its
orientation. Figure 7 shows the conventions for TrackPod orientation.
Positions shown correspond to a zero value and the arrows indicate the
direction of positive movement:
To enter manual calibration data, you select the TrackPod in the 3D
window and press the “location” button in the TrackPod inspector.
After TrackPod calibration
Once TrackPods have been calibrated they appear in the correct location
in the 3D window of the PC software. You will also see the stagemarks
showing the distances that you entered. It is very important that the
TrackPods not be moved from their exact 3D position or orientation
once they are calibrated. If they are moved, even slightly, it will be
necessary to recalibrate them (but you can use the same stage marks and
measurements if they have not changed since the last calibration).
Tip: once the TrackPods are calibrated you can prevent the TrackPod
operators to access the calibration menu, by setting the operator’s
“access priviledges” in the preferences>trackpods section.
