Client Tester Program
QuatView
includes a test program that demonstrates how to use the QuatViewClient class that is installed with QuatView.
The client tester program is a small GUI
application that simply reads a quaternion history file and transmits it to the QuatView server using the methods and properties provided by the QuatViewClient class as described here. Figure 20 shows the QuatView Client Tester GUI. The GUI has four input fields to
enter the server IP address, port number, playback file path, and the transmit delay
time. It also has two output fields that display the transmitted message count and
any status messages produced during the transmission. The bottom of the GUI has
two link buttons: one for connecting/disconnecting to/from the server and the other
for starting/stopping the quaternion transmissions.

Once a connection has been made to the QuatView server, the user can begin
sending the quaternion data file by clicking on the Transmit link button. The
program will then read and transmit the playback file with the specified delay time
between each quaternion. Alternatively, the user can request a variable or
"realtime" delay between each quaternion. This realtime delay is computed from the
time values in column 1 of the playback file.
Once a connection has been made or a transmission has begun, the user can stop
the transmission or disconnect at any time by clicking on the respective link button.
This will transmit a special stop signal or disconnect signal sent to the QuatView server. A stop signal will automatically be sent once the end of the playback file is
reached. If any network error occurs during the playback file transmission, then an
error signal will be sent so that the QuatView server can respond accordingly.
