Hi everybody!
I have AMD Barton 2500+ CPU and some A4Tech webcam. My CPU load is about 40% when Freetrack is active. Because of low FPS caused by CPU overload in the game (IL2) i was thinking about moving Freetrack and web camera to my notebook computer and send mouse output through the home network using Synergy software. I succeed to bring movement from my head to my desktop computer in this way: Head movement -> Web cam -> Freetrack (Notebook) -> Mouse movement (Notebook) -> Synergy server (Notebook) -> Network cable -> Synergy client (Desktop) -> Mouse movement (Desktop)... In windows.. mouse movement works well, but when enter the game, all mouse movement from notebook given by Freetrack, notebook mouse and touchpad are very raggedly and not precise. So.. does anyone tried something similar? I would like to hear if anybody have some idea why game don't understand both (desktop + notebook) mouse inputs in the same way, with the same precision and smoothing. Also, is there some chance and useful software to help Freetrack to send its output through the home network, but using "Direct game interface" option, because it will decrease webcam CPU load to zero. for people with more than one computer, at the same time it will be possible to send full 6DOF output from notebook, not just mouse XY. Thanks a lot! ~S~

Hehe, i was thinking about the same thing to take the load off the CPU for using two webcams if something like this:
http://forum.free-track.net/index.php?showtopic=492 is implemented. Anyway, would be great if FT could work in "slave" mode - not doing any actual tracking, but just receiving information from other instance of FT over LAN and generating proper output (direct game interface, ppjoy, mouse emulation) on the local machine. |

thanks for bringing that up, i've wanted to do this for quite a while now (IL2 is just way too sensitive to background CPU abuse).
i've always thought about way too complicated programming solutions, but your clever use of synergy made me realize that there had to be a solution around. and there is: using glovepie (famous for wii controller abuse, it's so damn mighty that it could even be possible to implement a wii-freetrack just with the built-in formula support...) i was able to pipe the freetrack data through OSC (kind of a midi successor for LAN, very good support in glovepie) from one computer to the other, with an instance of glovepie on each side. laptop (responsible for running freetrack, mine has a freshly hacked totally jitter free yet 100% responsive freetrackfilter mod, but that's another story, partially relevant for this one because it maybe takes a little more CPU) runs this simple script:
and the game computer runs this one: // this script reads input from a remote TrackIR and sends to game the IPs are obvious to change, the joystick buttons are for the recenter and (de)activate keys, replace for your favourite configuratoin enjoy! (i'll do as soon as i hit send)

Voila!
It took me about 5 mins to download and setup ....and it works great! Game view is now controlled through direct game interface GlovePie is very useful software. Thank you guys for helping me! I hope more people will find this thing useful. Thanks you usr also for writing this code, you make my day

Now, I just have a problem with re-centering. For this purpose, i am using F8 key on keyboard, and my stick button for centering is mapped to that key. But, for a some reason that doesn't work through this script. Maybe, there is some minor error in code that i can't see
i made changes to code for centering in this way, hope it's ok: |

Two things:
#1: when both glovepie and your joystick profile try to juggle around with virtual keystrokes i would not be too surprised if one could fail to read the virtual keystrokes of the other. i went straight to reading joystick buttons, but had to disable my joybutton->keystroke profile before it worked. #2: do the keys "pressed" by glovepie and the keys that freetrack listens to both match on your laptop? #3: i only announced two things, but i found a third issue, and this it's quite likely that it is the only one: i botched when copying the "laptop" script to my forum post, it's an outdated version that happened to live on my main computer and does not really work. please replace (on the "laptop" side) the lines if(osc.recenter) say("received") with if(osc.recenter) key.f11=true else key.f11=false this is also where you would change the keys if you want your freetrack to listen to some other keys. sorry for the inconvenience

this is really smart !!
Kestrel, are you thinking about this in the wishing list ? I'm also thinking about WideView User (maybe it's working allready with it though) |

There is the video I made, where you can see it in action.
Also, I replaced LEDs with reflective textile points on hat in combination with 6 IR illuminating LEDs mounted on A4Tech webcam. http://veljovic.blogspot.com/2008/01/head-tracking-update.html |

Me again
After a short time period, i found setup discussed above still working perfectly in IL2. But i have question for usr, or someone else who knows, is there some code i should add to this script on local computer script to make this Freetrack emulation work with MS FSX? Thanks a lot!

sorry, i have absolutely no idea how fsx does the looking thing. my microsoft flight simulator experience lies almost exclusively in abusing the FS4 "airplane designer" in attempts to build canard configurations that would make it off meigs peninsula in one piece or "roadworthy" supersonic jet cars (i was 12 or so)

everything is ok! i have tested freetrack on local machine and it works with no problems |

Hey guys, there's one problem here - the script will only work with GlovePIE 0.30. As of this date the "official" webpage lacks a download link for this version, stating that Version 0.30 has serious bugs in the Wiimote code that prevent it from reading the Wiimote motion sensor calibration when IR is also used in the script. Please use version 0.29. A new version of GlovePIE should be released shortly. So, the solution is simply to download it from another place while the author comes up with an update.
The exact issue is that in previous versions, the "FakeTrackIR" variable is not defined, so you get "compile" errors on the respective lines in the script. Cheers. |

Thanks to dimothy for that new...i almost lost half of my hair trying to set it up.

Hi Folks,
this sounds very easy but it isn´t with FS2004. I tried it and I can see the changing values in the debug line at the FS-part of glovepie but nothing happens in FS2004. Did somebody test this with FS9? Do I have to install something at the FS-side PC? Perhaps TrackIR or tirviews.dll or something with OSC? It would be great to have a fiew fps more with this constallation. Thanks for any answer /eisenfpferd/ |
