- Three levels of API?
- Low level (equivalent to Geant4 geometry objects)
- Initially dumb objects, sufficient to create Geant4 geometry
- Medium level (similar to GEAR::Vertex::API)
- High level (allows finding which detectors exist)
- Low level (equivalent to Geant4 geometry objects)
- have collection of driver classes
- one subdetector level
- gcj comliant Java ( to be called from C++/Marlin)
- read in 'free format' from parameters from xml elements
- should probably be similar to compact/gear
- low level implemetation:
- create "queue" of geometry instructions
- logical volumes
- physical volumes
- placements
- material
- etc
- have converters that go through queue of instructions and create
- G4Detector
- HepRep
- GDML / LCDD
- create "queue" of geometry instructions
- medium and high level: GEAR++ interface(API)
points to cover
- GEAR++ interface deifinition (medium and high level)
- tracking (and clustering PFA)
