Some freetrack questions

That's what they do.

You don't need to tell it where your head is relative to the camera.

I tend to work close to the screen and found an improvement in the Z axis (FOV) response by moving the ref point backwards by -100mm or so. You don't have to do this but it worked for me in FT 6DOF is all I am saying. My 3 point clip is horizontal and on headphones (rather than a hat).



You must enable the TrackIR interface checkbox and not the Freetrack Interface for IL2 (in the FT software Output menu). If the skull is moving then you should see movement in the game since you already have TrackIR enbled in your config file.

I use infrared (IR) diodes that I sanded down to enhance the brightness. This way I can use in full sunlight.

We haven't gotten a fix on whether freetrack will work with BOB COD, because TrackIR has been working on some things to make TrackIR proprietary enough that headtracker wannabe cannot steal their business.

We will probably learn the outcome soon as information is released on the COD.

For now, the Freetrack works very well with Il2

I only did the freetrack, because I enjoy doing the electronic gimmickery.
My head piece took all day one Saturday to built, but it is just perfect for freetrack. It is built in very compact package and slides into a clip on my headset. Very professional, and it works extremely well every time I use it.

Steal?
You mean "compete for".

I don't know. I get your point, but most of the packages that would do what TrackIR is supposed to do are free. So... I don't think in terms of competition when they aren't trying to make money. Actually, if they were real viable competitors they would probably have to do some competent workarounds in the code not to be sued.

Whatever sounds best to you is fine with me.

Yeah, I think what TrackIR are trying to do to freetrack is like a supermarket trying to stop you growing your own vegetables in your back garden by sabotaging your seedlings that the friendly farmer gave you.
Its not right and its not fair. You should be able to make something you could otherwise buy, using separate items you bought or were given.

Another example: You buy a ball of wool (LEDs, resistors and batteries). You already have some knitting needles (webcam). Your Gran then teaches you how to knit a scarf (freetrack software). Then along comes someone from Topshop (TrackIR) and breaks your poor gran's hands.

well, actually i'm using freetrack clip for my headset done with drinking straws, white leds, non IR, and a ps3 eyecam at 640x480@75fps and works very well, without any filter removed. I really hope freetrack can be used with COD.

Camera settings: I think the most important thing is that your room lighting doesn't change during various times of the day. This can be a real hassle. Maybe one lamp in the background. I use lens from old ski goggles with yellow tint for filter. I tried exposed film, but it was too dark. I also did not remove or mod my web camera. In the camera settings, I zero out the following settings: sharpness, constrast, white balance, saturation. I max out brightness and gain. My camera has max 30 fps, so I set exposure to 1/30 seconds. Freetrack does a trick and produces an output at 120 fps. Automatic gain control is off and anti flicker is on. I also use RGB24 for stream/compression. With my camera settings, it is very easy to find where to dial the threshold in. There is not much "in between". It's either all red and not working, all black and not working, or it is working as one fairly fat red dot.

In your web camera software, try making the aspect ratio that your camera produces the same or as close as possible to your monitor and do the same in the freetrak camera section. I don't mean resolution (as the camera will likely produce much lower resolution than your monitor) I mean aspect ratio. I feel like the freetrack curves fit the rotation of my head better when I do this. If you can't match the ratios exactly because of the options the software provides, try to get as close as possible (e.g., all widescreen ratios).

Also, I use filed infrared led.

Don't talk about things you don't know.

FreeTrack has your OWN API. FreeTrack "steals" nothing. Tha math behind tracking points in space is free.

Bohemia Interactive deliver FreeTrack support. If IL-2:CoD didn't do the same, will be a real shame.

FreeTrack don't use new encripted NP API. Devs can use FreeTrack API, as Bohemia Interactive did, and to a decent job.

If IL-2:CoD didn't came out of box with FreeTrack support, shame.
