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 | |
