Hi,
i'm trying to use OptiTrack SDK to perform head tracking in a 3D CAD application. I'm using a TrackIR 5 camera, but i'm having some problems with value of variables. I know that INPVector class isn't officially supported but i'd like to try the device to understand if it can be used in my application.
I'd like to know witch is the output range of each variable coming from the device.

I hope someone can help me...thanks!

There isn't a specific hard limit for the translation axes (X,Y,Z) but there is a practical limit based on how much the device can move in mm (possible non-linearity of results aside).

The output of rotational axes will be constrained by the amount you can rotate the tracked clip from its original orientation and still have all of the reflectors tracked.
