1. Visualisation Tool Dave Bailey

2. What Do You Need?  Various packages –CLHEP  Use version >= 1.8.2.0 as there is a bug in anything earlier.  I used CLHEP 2.0.1.0 –Qt –Coin  Both are freely available on *nix. I just got the latest versions of both

3. Building  Compiling the vis package is straightforward –Just change the 4 top level makefile includes to point to your versions of CLHEP, Qt, Coin –If using CLHEP < 2.0 no changes needed  Make sure CLHEP is a shared library, static didn’t seem to work for me…  If using CLHEP > 2.0 you need to add using namespace CLHEP; to the top of Drawables/Ellipsoid.cc

4. Running It…  Package requires you Xserver to support OpenGL (GLX extension in the jargon) –If you’re on a *nix console, no problem –If you run Exceed on a windows box you’ve had it!  No support for GLX unless you buy Exceed3D which costs more for a site license than Exceed itself –Maybe look at using XWin-32 as that has GLX support  Or, perhaps, look at making the software more friendly to non-OpenGL systems. It ought to be possible –Most likely a question to take up with the authors

5. This is what you get Reconstructed Vertex Monte Carlo vertices and particles

6. Overall  It’s OK… –I didn’t find it all that easy to drive  Lack of documentation doesn’t make life easy… –It does let you examine individual objects –You can rotate, zoom etc. –You can save pictures in postscript  I’d suggest that a few more of us give it a try for now
