There where free headtracking systems wayyyy before NaturalPoint.
Cam2Pan started before TIR1.
freetrack interfaces with it's own DLL when it can (i.e. the latest beta of
armaII). when that is not there it uses NP's old interface. NP's new interface
is not used at all by freetrack.
Freetrack is not only free, but the software offers more options than NP's.
Many freetrack setups work better than TIR in sunlight as well.
If anyone wants a freetrack headset made, then PM me.
