TrackIR vs Freetrack/Freelook/etc etc
[Or how to get a taste of what TrackIR is like, so that it will probably make you desire one even more!!!! Well that is what happened to me!!]
I have tried most of the alternatives to TrackIR,
The main problems are:
a) Framerate Hits: as these are software solutions, they require more CPU ticks to do their computations, from what I can tell, TrackIR seems to do alot of its processing on its own hardware chip. TrackIR framerate his is negligable (5% maybe) ... while the software versions are 20-60% frame hits.
b) Quality: TrackIR is basically a modified webcam, that appears to have the essential things it requires significantly boosted, and the stuff it doesnt need discarded (i.e. has very fast FPS, but only looks for IR-light, so discards images etc etc). When using a webcam, you have to tweak etc etc to get it to within paramaters that the software can comfortably work with.
* I ended up in a totally darkened room, with an IR-led on my hat, and if i moved too far it didnt respond or lost tracking. (i would call it a 65%-85% solution).
* With trackIR ... can use it in any light, at very good angles/distances ... I would say it is a 100-110% solution ... once you get used to it (especially doing a 6-look, which might take a few days) ... it becomes 2nd nature.
I sound like an advertisment for TrackIR, but CAUTION/BEWARE ANYONE trying these software alternatives ... you know what it is going to do ... once you get a feel for 6DO and head-panning ... you will desire the real TrackIR even more...lol
(Played with s/w and cam for 7 days ... then saved my pennies and bought a TrackIR ... took me 3-4 weeks of no-takeaway etc and didnt even have to increase my mortgage!!!..lol)
