How can user access the linear and rotational velocity and acceleration of a rigid body using TT? Using this callback handler? // (un)Register a callback handler to handle an acceleration change virtual int register_change_handler(void *userdata, vrpn_TRACKERACCCHANGEHANDLER handler, vrpn_int32 sens...

In "vrpn_Tracker.h", // Description of the next report to go out vrpn_int32 d_sensor; // Current sensor vrpn_float64 pos[3], d_quat[4]; // Current pose, (x,y,z), (qx,qy,qz,qw) vrpn_float64 vel[3], vel_quat[4]; // Cur velocity and dQuat/vel_quat_dt vrpn_float64 vel_quat_dt; // delta time (i...

<t>I'm wondering if TrackingTools estimates the linear and angular velocities and accelerations?<br/> <br/> I found some protected variables related to velocities in the sample codes. But don't know how to access them.<br/> <br/> I guess these variables are commonly used in many applications. It wil...
