Pink Octopus and Top Numbers

[chsims1]

Hi, I'm trying to decide if opentrack is tracking or not when using pointtracker. I have three crosses following my leds nicely in the video stream, and values displayed for raw translation and rotation. There are no numbers displayed at the top next to the pink octopus. Should this be moving like in FTNoIR?

Secondly, I cannot get opentrack to work with flightgear. I have set the flightgear output settings to 127.0.0.1 and port 5542 in opentrack. I have copied:

clientfiles/FlightGear/Protocol/headtracker.xml to FlightGear/data/Protocol/headtracker.xml

and have tried to run flightgear with:

fgfs --generic=socket,in,25,localhost,5542,udp,headtracker

I'm sure that I am doing something stupid, but I cannot see what.

Regards,

Ian Sutherland

Need to go to the mapping window and set the actual translation of input to output. Linear is recommended! Any kind of "deadzone" is pessimal and hurts muscle memory. If output is jerky, use the Accela filter instead and set it up to your liking for a balance between latency and idempotence.

Once you get this to work, flightgear will automagically work.

I'm really sorry, but I don't understand this. Ok, go to mapping window and options are Centre pose, Translation compensation and Axis inversion.The last one I understand. What do the other options do? The other tabs are graphs of how head motion is interpreted (presumably). How do I set the actual translation of input to output? If I get this working then I will produce some documention along the lines of "idiots guide to.." if only to remind me in a few months :)

Left-click on the blue-background graph to set a control point. Right-click on one to remove it. Left-drag to move it.

Gotcha...now I understand. I'd not bothered with the mapping thinking that I would do it later after things were working properly. I didn't realise it was an integral part of the tracking process.
