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 |
