From Andrei Gheata:
modifications needed for adding tracks for which
you do not know the parent at creation time.
creation:
TVirtualGeoTrack *TGeoManager::MakeTrack(Int_t id, Int_t pdg, TObject
*particle=0)
adding as daughter to other track:
Int_t TVirtualGeoTrack::AddDaughter(TVirtualGeoTrack *other);
returning the new daughter index.

New version of the geometry package from Andrei:
4 new files:
geom/inc/TVirtualGeoTrack.h
geom/src/TVirtualGeoTrack.cxx
geompainter/inc/TGeoTrack.h
geompainter/src/TGeoTrack.cxx
This new version adds support for track visualization. Adding tracks is a user task
and can be done using :
TGeoManager::AddTrack() for primary tracks. The manager class knows
about the current primary and provides utility methods to
retreive/change this. Users has to handle only TVirtualGeoTracks.
Secondaries can be added to their primary :
TVirtualGeoTrack::AddDaughter()
Points (x,y,z,tof) can be associated with a track :
TVirtualGeoTrack::AddPoint()
Providing tracks to the modeller and adding points are users tasks.
Track names should be supplied by users after creation :
TVirtualGeoTrack::SetName() - note that tracks are not tnamed
objects, but their names are globally handled by the TGeoManager. The
usage of ROOT default particle names are recommended for tracks since it
triggers special colors/line attributes.
Tracks are drawable/pickable objects. Drawing options are :
- default - only current track drawn
- /D - track and first level daughters
- /* - track and all descendents
- /N<name> - only tracks from particles with given <name>
If points with time of flight are supplied, the drawing range tmin,tmax
can be specified :
TGeoManager::SetTminTmax() (if no arguments time cut is supressed)
Tracks can be animated individually or global :
TVirtualGeoTrack::AnimateTrack(tmin,tmax,nframes,option)
TGeoManager::AnimateTrack(tmin,tmax,nframes,option)
Animation otions are :
/G - animate also geometry in the given time interval
/S - save all frames as .gif files
drawing options act as well in animation. Options can be concatenated
and should be upper case (due to /N<name>)
If tracks are defined, the geometry I/O takes them into account.
However, when loading a geometry file containing tracks, libGeomPainter
has to be loaded since it contains the class implementation definition :
gSystem->Load("libGeom")
gSystem->Load("libGeomPainter")
TGeoManager::Import("mygeom.root")
