Note: supported just for compatibility. It is recommended to use the
newer Measurement Tool format
6dmt2
(see chapter B.2.7 on page 263)
whenever possible.

Only available, if the Measurement Tool license is present for
DTrack2 (available since version v2.2.0)
The output for Measurement Tools is similar to the format for Flysticks:
•
The first number gives the number of defined Measurement Tools .
•
The data of each tool show up in blocks (three consecutive
[]
), like:
[id qu bt][

They contain:
1. ID number (
id
, starting with 0 ), quality value (
qu
, see below) and button infor-
mation (
bt
, unused),
2. Measured position (
s
i
) of the tip,
3. Rotation matrix ( b
i
) of the tip’s orientation.
•
The quality (
qu
) can (so far) just get the values 1 . 0 and
−
1 . 0 .
−
1 . 0 means that the
target of the Measurement Tool is not visible at the moment.
•
The protocol is prepared for future Measurement Tools equipped with buttons (like
Flysticks). Until then
bt
is set to zero.
