Detailed Description

EEmc Tower and Track Display class.

Author:

Piotr A. Zolnierczuk, Indiana University Cyclotron Facility

Date:

2004/01/19

This is a simple root TGeoXXXX based class. It displays EEMC tower geometry (the class inherits from EEmcGeomSimple) and allows for "turning on/off" individual towers as well as it displays muDST tracks (StMuTrack).

Sample snapshot

Remarks

Todo:

[medium] private member volumeName is not best implemented

[minor] speed of light redefined (should be taken from StarClassLibrary)

Bug:

the class requires an explitic set of magnetic field via SetMagneticField
