Re: Positioning and reference grid

<t>[quote=NaturalPoint - Birch Zimmer]If you are not using a TrackIR3/TrackIR4 you may want to update the lens parameters to get more accurate readings. This can be done using INPVector3. You may still experience some axis crosstalk and non-linearity after the lens parameters are updated, its not un...

Acquisition with Track IR 5

<t>I have Track IR 4, for which I have written some code (using the OptiTrack API) that works. Now I bought the Track IR 5, and the same code that worked for Track IR 4 doesn't work for Track IR 5. The sensor's LEDs don't light up and there's no acquisition going on. The code that I use to open/star...
