KLOE Event Display Demonstration

The "o" packages are installed on the LNF UNIX cluster. So far I have created this demo for HP-UX only. The OSF/1 version will be available soon (I have just to compile and like the program).


% setenv DISPLAY <YourDisplay>:0
% cd ~wolf/o/Vis/v0/src

or if you just have a back&white X-terminal (like me) type:


% cd ~wolf/o/Vis/v0/src/bw

Then setup the Vis package and run the program:


% source ~wolf/o/Vis/v0/mgr/setup.csh
% $VISBIN/Vis.exe &

Here we go, now you should have the event display windows on your screen.

Select the Open file option in the File menu.
Select a file from the 10**6 event production. Then you should see the first event displayed. Please do not ask me what type of events is in the selected file. For sure, Caterina Bloise or somebody else can tell you.
Move the cursor in one of the display windows and click the right mouse button and select rotate. Then press the control key and move the mouse at the same time allowing you to rotate the detector in 3D. How fast you can rotate depends mainly on the CPU power of your box or the network speed.
Do the same with the scale option to zoom in and out.
Click on a module hit or use the rubberband box to pick and highlight more of them. Then the properties of this picked modules are displayed in the Wo console.
To zoom display objects for example module hits press and hold the Shift-Control key and the left mouse button and move the mouse to define the zoom area. After the release of the mouse button the area will be enlarged. Use the right mouse button and select back to unzoom.
Select the Print option in the File menu to create a postscript file.
Play with the other options in the Event and View menu.
Type control-e to read and display the next event.

You do not like the colors? The Motif interface is completely interpreted so you can modify them by yourself without recompiling the program. Copy the interface files Vis.odb and user.odb to your own directory, move there and modify them. Search for the string color in user.odb to see how colors are set. Then restart the Vis program as described above:


% $VISBIN/Vis.exe &

Now you should have some first impression. It think it's quite impressive so far.

Will be continued ...
