B.2 Output of Measurement Data via Ethernet
• The first number gives the number of defined Flysticks.
• The data of each Flystick show up in blocks (three consecutive []) like:
[id qu bt][s

They contain:
1. ID number (id, starting with 0), quality value (qu, see below) and button infor-
mation (bt, see below),
2. Position (s
i
) and orientation angles (η θ φ) and
3. Orientation (b
i
) of the Flystick.
• The quality (qu) can (so far) just get the values 1.000 or −1.000. −1.000 means
that the target of the Flystick is not visible at the moment. Even in that case a
Flystick appears in the output data. Then dummy values are used for position (zero)
and orientation (zero matrix!). Informations about buttons are valid as long as the
wireless transmission is active.
• When buttons of the Flysticks are pressed the (decimal) number bt changes. It is
coded binary (i.e. switch 1 activated = bit 0 set, switch 2 activated = bit 1 set, . . . ).
Example (one line):
6df 1 [0 1.000 2][261.103 116.520 41.085 19.6522 -57.3530 116.5992]

B.2.7 Measurement Tools with sphere tip
Identifier 6dmt2.
Z
Note: this format version replaces the older 6dmt format (see B.2.9).
Use it whenever possible.
i
Only available, if the Measurement Tool license is present for
DTrack2 (available since version v2.9.1).
The output for Measurement Tool with sphere tip is defined as follows:
• The first number gives the number of calibrated Measurement Tools .
• The second number gives the number the following target data.
• The data of each tool show up in blocks (five consecutive []), like:
