Detailed Description

A tracker is an interface to a tracking subsystem such as VRPN. As such it might have several different types of sensors attached to it.

Constructor & Destructor Documentation

Tracker::Tracker (  std::size_t  numTrackers = 0  )  [protected]

constructor automatically creates as many TrackedTransforms as passed as parameter

---

Member Function Documentation

TrackedTransform * Tracker::getTransform (  std::size_t  pos  )

Return the reference to the ith tracked transform in the sensor. Is this the same as a sensor number? Parameters: pos  the position on the list Returns: a pointer to a trackedTransform

bool Tracker::requestSensor (  unsigned int  sensorID  )  [virtual]

request a sensor. Parameters: sensorID  the sensor ID. Returns: true if sensor exists. False if this sensor is not available. Reimplemented in osgTracker::VRPNTracker.

void Tracker::setTransform (  std::size_t  pos, TrackedTransform *  xform )  [protected]

store the tranform xform as the element in the position pos on the list of transforms Parameters: pos  the position on the list xform  the transform Returns: a pointer to a trackedTransform
