PointTracker
Many users asked us, if it would also be possible to merge the IR-tracker of FreeTrack into FaceTrackNoIR. Many already have a headset (3-point model) and would like to use the advanced features offered by FaceTrackNoIR combined with the fast IR-tracking of FreeTrack. Though the name clashes a bit with the "NoIR" part in the name FaceTrackNoIR, Patrick made this conversion of PointTracker.

Advantages
The great advantage of IR-tracking compared to face-tracking is the fact that only a few points (mostly 3 IR-leds) need to be tracked. This requires much less CPU-power than face-tracking. So this will offer either a lower CPU-load (giving 'the game' more power) or the tracking-frequency can be higher (giving higher accuracy).
Drawbacks
IR-tracking can be difficult, when the environment of the user is too brightly lit or if light-sources are located behind the user. Also, a 3-point model must be made to which IR-leds are attached. Examples and descriptions of how to make such a model can be found here on FreeTrack.
Settings
A full explanation of the settings can be found here on sourceforge
The Settings-screen of PointTracker looks like this:
Using the Enable axis checkboxes each of the 6 DOF's can be enabled or disabled. Disabled means, that the output value will not be sent to FaceTrackNoIR.
