Why Head Tracking?

[Uufflakke]

I experimented a bit with TrackNoIR a month ago and actually it works very good.
No hatclip with reflectors or LEDs needed. Just a webcam and their freeware.
But decided to switch back to Freetrack for a simple reason. TrackNoIR needs sufficient light shining on your face to make it work. My PC isn't positioned to a window or lamplight in front of me so the yellow tracking lines didn't appear. And then it became a real CPU eater.
When I tried it out with extra lamplight everything was okay and it was not CPU demanding anymore.
More info about TrackNoIR, its tweaking and settings you can find at one of the modsites. Don't know if I'm allowed to mention the name here.
