18// Class AliMUONSlatGeometryBuilder
19// -------------------------------
20// Abstract base class for geometry construction per chamber.
21//
f4a7360f 22
2057e0cc 23
24
c10e6eaf 25// This Builder is designed according to the enveloppe methode. The basic idea is to be able to allow moves
26// of the slats on the support panels.
27// Those moves can be described with a simple set of parameters. The next step should be now to describe all
28// the slats and their places by a unique
29// class, which would make the SlatBuilder far more compact since now only three parameters can define a slat
30// and its position, like:
2057e0cc 31// * Bool_t rounded_shape_slat
32// * Float_t slat_length
33// * Float_t slat_number or Float_t slat_position
cd8824a7 34// Reference system is the one described in the note ALICE-INT-2003-038 v.2 EDMS Id 406391
