Detailed Description

a class for parsing .mt files output by the Polaris software

At present, the acquired motion tracking data is formatted as

  23/5/2003 18:18:32 - 11 1 966_IRSL_II
  record
  record
  ...

where each record is a line containing the following numbers

    Sample Time (secs since midnight in local time)
    Random #
    Tool Number (as a character)
    Q0, Qx, Qy, Qz
    Tx, Ty, Tz
    RMS Error

or something like

67820.806  2 A : ---- Missing ----

when the Polaris was not able to find the position of the tool.

Warning: All times are in local time, and are hence subject to the settings of your TZ environment variable. This means that if the data is processed in a different time zone, you will run into trouble.
