This is where we want to arrive:

SLIC

Generic G4Driver

Database(Mokka)

getparams

Geant4

Detailed Geometry

create volumes / vis attrs

-Reconstruction-Alignment-Analysis

Processor(s)

Access according to needs

detailed geo+ visualization attrs

Geant4Visualization

Event Display

Parametrized Geo.

geometry+ visualization attrs

There would be only one leftfor all subdetectors and all models

Alignment const.

Calibration const.

Visualization attrs.

The Goal

SLIC

Idea was a bit too naïve:geometry (automatic conversion) is not enoughalso need sensitive detectors
