|---|
| 5 | # |
|---|
| 6 | # This program is a test harness for the VtkVis visualization |
|---|
| 7 | # engine. It allows you to monitor the commands being sent back |
|---|
| 8 | # and forth between a standard Rappture application and the VtkVis |
|---|
| 9 | # server. You can also send your own commands to the server, to |
|---|
| 10 | # debug new features. |
