Bonjour a tous,

J'ai télécharger et installer parfaitement bien FreeTrack pour mon pc.
En regardant dans les dossiers, j'ai trouvé freetrack_c_interface.cpp
Or j'aimerai utilisé freetrack dans un programme en cpp perso

Es ce qu'il y a une personne qui sait comment utilisé ce fichier car j'ai rien trouvé dans la doc.

je vous remercie pour votre réponse

Il faut poser cette question à "The_target" !  :rolleyes:

Ce fichier fait partie du "SDK FreeTrack" à l'intention des développeurs qui souhaiteraient implémenter FreeTrack dans leur logiciel !

Ces commandes sont envoyées à FreeTrack par l'intermédiaire de la DLL "FreeTrackClient.dll"

Dans le SDK tu as aussi un fichier "FreeTrackTest.exe" qui permet de valider si ton application envoie bien les données de tracking ... #3 30/01/2009 - 17h44

Sorry but I only able to read french :)

I've been reviewing the code of freetrack_c_interface.cpp and is outdated, mainly because the data structure that is supposed to fill is outdated with respect to v2.2.

The updating seems trivial if you look at

TFreeTrackData = packed record
   DataID : Cardinal;



and compare it to the struct in


There is also a function that seems to be missing in the current FreeTrackClient.dll,
you can comment its occurrences in
freetrack_c_interface.cpp, surely you won't need it.

It would be desirable to find freetrack_c_interface.cpp within the source code, and some reference to C++ interfacing in the FAQ or manual.

Right now we are reading the 6DOF from a WiiMote using the corrected version of freetrack_c_interface.cpp,

What can be done to calibrate the given numbers to to exact physical positions, for example relative to a reference in the camera of the WiiMote??. We are thinking about using WiiMote to get the position of the head of a robot (because we don't have absolute encoders), and this requires some degree of precision in physical space.
