HOWTO visually inspect the simulation geometry

This page shows how to use geant++ and root to check if the detector geometry has been done right.

Using hdgeant++

• hdgeant++ is based on GEANT3 and uses also paw. So being familiar with kumac is usefull. To check if some modification in an xml file has been done correctly you do the followoing:

1) generate the geometry fortran file in the hdds directory by "make hddsGeant3.F" 2) copy hddsGeant3.F into the HDGeant directory and recompile hdgeant++ by "make clean; make" 3) make sure you have "wc.kumac" and "wc.f" in your working directory 4) start "hdgeant++" in your working directory
