const eq::Matrix4f& Tracker::getMatrix

(

)

const [inline]

Gets the transformation matrix with the position and orientation data.

This function will not communicate with the tracker,.

Returns:

the transformation matrix.

bool Tracker::init

(

const std::string &

port

)

Configures the serial port and initialises the tracker.

Sets the _running state to true if the initialisation is successful.

Parameters:

port	the used serial port.

Returns:

true if the tracker works correctly, false otherwise.
