Also when Alternative Pitch curve is used. 20120805 - WVR: The FunctionConfig-widget is used to configure the Curves. It was tweaked some more, because the Accela filter now also uses the Curve(s). ToDo: make the ranges configurable by the user. Development on the Toradex IMU makes us realize, that a fixed input-range may not be so handy after all.. 20120427 - WVR: The Protocol-code was already in separate DLLs, but the ListBox was still filled �statically�. Now, a Dir() of the EXE-folder is done, to locate Protocol-DLLs. The Icons were also moved to the DLLs 20120317 - WVR: The Filter and Tracker-code was moved to separate DLLs. The calling-method was changed accordingly. The face-tracker member-functions NotifyZeroed and refreshVideo were added, as requested by Stanislaw. 20110411 - WVR: Finished moving all Protocols to separate C++ projects. Every protocol now has it's own Class, that's inside it's own DLL. This reduces the size of the program, makes it more structured and enables a more sophisticated installer. 20110328 - WVR: Changed the camera-structs into class-instances. This makes initialisation easier and hopefully solves the remaining 'start-up problem'. 20110313 - WVR: Removed 'set_initial'. Less is more. 20110109 - WVR: Added setZero option to define behaviour after STOP tracking via shortkey. 20110104 - WVR: Removed a few nasty bugs (it was impossible to stop tracker without crash). 20101224 - WVR: Removed the QThread inheritance of the Base Class for the protocol-servers. Again, this drastically simplifies the code in the protocols. 20101217 - WVR: Created Base Class for the protocol-servers. This drastically simplifies the code needed here. 20101024 - WVR: Added shortkey to disable/enable one or more axis during tracking. 20101021 - WVR: Added FSUIPC server for FS2004. 20101011 - WVR: Added SimConnect server. 20101007 - WVR: Created 6DOF-curves and drastically changed the tracker for that. Also eliminated a 'glitch' in the process. 20100607 - WVR: Re-installed Rotation Neutral Zone and improved reaction after 'start/stop'. MessageBeep when confidence is back... 20100604 - WVR: Created structure for DOF-data and changed timing of ReceiveHeadPose end run(). 20100602 - WVR: Implemented EWMA-filtering, according to the example of Melchior Franz. Works like a charm... 20100601 - WVR: Added DirectInput keyboard-handling. '=' used for center, 'BACK' for start (+center)/stop. 20100517 - WVR: Added upstream command(s) from FlightGear 20100523 - WVR: Checkboxes to invert 6DOF's was implemented. Multiply by 1 or (-1). */ #include "tracker.h" #include "facetracknoir.h" /** constructor **/ Tracker::Tracker( FaceTrackNoIR *parent ) : confid(false), should_quit(false), do_center(false) { // Retieve the pointer to the parent mainApp = parent; // Load the settings from the INI-file loadSettings(); } Tracker::~Tracker() { } static void get_curve(double pos, double& out, THeadPoseDOF& axis) { bool altp = (pos < 0) && axis.altp; if (altp) { out = axis.invert * axis.curveAlt.getValue(pos); axis.curve.setTrackingActive( false ); axis.curveAlt.setTrackingActive( true ); } else { out = axis.invert * axis.curve.getValue(pos); axis.curve.setTrackingActive( true ); axis.curveAlt.setTrackingActive( false ); } out += axis.zero; } /** QThread run method @override **/ void Tracker::run() { T6DOF current_camera; // Used for filtering T6DOF target_camera; T6DOF new_camera; /** Direct Input variables **/ T6DOF offset_camera; T6DOF gameoutput_camera; bool bTracker1Confid = false; bool bTracker2Confid = false; double newpose[6]; double last_post_filter[6]; forever { if (should_quit) break; for (int i = 0; i < 6; i++) newpose[i] = 0; // // The second tracker serves as 'secondary'.
