085bb6ed | 61 | // The structure AliITSgeomS: |
62 | // The structure AliITSgeomS has been defined to hold all of the | |
593e9459 | 63 | // information necessary to do the coordinate transformations for one |
64 | // detector between the ALICE Cartesian global and the detector local | |
65 | // coordinate systems. The rotations are implemented in the following | |
66 | // order, Rz*Ry*Rx*(Vglobal-Vtrans)=Vlocal (in matrix notation). | |
67 | // In addition it contains an index to the TObjArray containing all of | |
68 | // the information about the shape of the active detector volume, and | |
69 | // any other useful detector parameters. See the definition of *fShape | |
70 | // below and the classes AliITSgeomSPD, AliITSgeomSDD, and AliITSgeomSSD | |
71 | // for a full description. This structure is not available outside of | |
72 | // these routines. | |
73 | // | |
74 | // Int_t fShapeIndex | |
75 | // The index to the array of detector shape information. In this way | |
76 | // only an index is needed to be stored and not all of the shape | |
77 | // information. This saves much space since most, if not all, of the | |
78 | // detectors of a give type have the same shape information and are only | |
79 | // placed in a different spot in the ALICE/ITS detector. | |
80 | // | |
81 | // Float_t fx0,fy0,fz0 | |
82 | // The Cartesian translation vector used to define part of the | |
83 | // coordinate transformation. The units of the translation are kept | |
84 | // in the Monte Carlo distance units, usually cm. | |
85 | // | |
86 | // Float_t frx,fry,frz | |
87 | // The three rotation angles that define the rotation matrix. The | |
88 | // angles are, frx the rotation about the x axis. fry the rotation about | |
89 | // the "new" or "rotated" y axis. frz the rotation about the "new" or | |
90 | // "rotated" z axis. These angles, although redundant with the rotation | |
91 | // matrix fr, are kept for speed. This allows for their retrieval without | |
92 | // having to compute them each and every time. The angles are kept in | |
93 | // radians | |
94 | // | |
95 | // Float_t fr[9] | |
96 | // The 3x3 rotation matrix defined by the angles frx, fry, and frz, | |
97 | // for the Global to Local transformation is | |
98 | // |fr[0] fr[1] fr[2]| | cos(frz) sin(frz) 0| | cos(fry) 0 sin(fry)| | |

105 | // | |
106 | // Even though this information is redundant with the three rotation | |
107 | // angles, because this transformation matrix can be used so much it is | |
108 | // kept to speed things up a lot. The coordinate system used is Cartesian. | |

154 | // | |
155 | // Int_t fNlayers | |
156 | // The number of ITS layers for this geometry. By default this | |
157 | // is 6, but can be modified by the creator function if there are | |
158 | // more layers defined. | |
159 | // | |
160 | // Int_t *fNlad | |
161 | // A pointer to an array fNlayers long containing the number of | |
162 | // ladders for each layer. This array is typically created and filled | |
163 | // by the AliITSgeom creator function. | |
164 | // | |
165 | // Int_t *fNdet | |
166 | // A pointer to an array fNlayers long containing the number of | |
167 | // active detector volumes for each ladder. This array is typically | |
168 | // created and filled by the AliITSgeom creator function. | |
169 | // | |
085bb6ed | 170 | // AliITSgeomS **fGm |
171 | // A pointer to an array of pointers pointing to the AliITSgeomS | |
593e9459 | 172 | // structure containing the coordinate transformation information. |
085bb6ed | 173 | // The AliITSgeomS structure corresponding to layer=lay, ladder=lad, |
174 | // and detector=det is gotten by fGm[lay-1][(fNlad[lay-1]*(lad-1)+det-1)]. | |
593e9459 | 175 | // In this way a lot of space is saved over trying to keep a three |
176 | // dimensional array fNlayersXmax(fNlad)Xmax(fNdet), since the number | |
177 | // of detectors typically increases with layer number. | |
178 | // | |
179 | // TObjArray *fShape | |
180 | // A pointer to an array of TObjects containing the detailed shape | |
181 | // information for each type of detector used in the ITS. For example | |
182 | // I have created AliITSgeomSPD, AliITSgeomSDD, and AliITSgeomSSD as | |
183 | // example structures, derived from TObjects, to hold the detector | |
184 | // information. I would recommend that one element in each of these | |
185 | // structures, that which describes the shape of the active volume, | |
186 | // be one of the ROOT classes derived from TShape. In this way it would | |
187 | // be easy to have the display program display the correct active | |
188 | // ITS volumes. See the example classes AliITSgeomSPD, AliITSgeomSDD, | |
189 | // and AliITSgeomSSD for a more detailed example. | |

234 | // | |
235 | // Int_t GetStartSPD() | |
236 | // This functions returns the starting module index number for the | |
