See alsoClass DescriptionBrDetectorVolume is a BRAHMS base class providing information about detector geometry, and uniform access to a specific detector that may have additional information. Some of the basic functionality is that each detectorvolume contains a BrCoordinateSystem information and thus enable transformation between Local, Global and other Master Systems. In addition there are definitions of other volume parameters as active volume, shape etc. that can be helpful in projection of lines to detector specific planes. BrDetectorVolume():TNamed() Default Constructor. Set counter and list data members to zero. Don't use this constructor unless you have to and know what you are doing BrDetectorVolume(const Char_t *name, const Char_t *title, const Char_t *ASCIIFileName) :TNamed(name,title) This constructor should only be used in stand alone application / and not in connection with the VolumeDbManager. BrDetectorVolume(const Char_t *name, const Char_t *title) :TNamed(name,title) Normal named constructor BrDetectorVolume(const Char_t *name, TObjArray *asciiVolList) :TNamed(name,name) Constructor called from BrGeometryDbManager in MySQL mode BrDetectorVolume(const Char_t *name, const Char_t *title, Float_t sizeX, Float_t sizeY, Float_t sizeZ, BrVector3D& origin, BrRotMatrix& rotMatrix) :TNamed(name,title) Constructor specifying size, origin and rotMatrix directly ~BrDetectorVolume() SetVolumeParameters(float xl, float yl, float zl, float angle, float beta, float xl_center, float yl_center, float zl_center, char *type) void AddVerticalRotation(Float_t &theta2,Float_t &phi2, Float_t &theta3,Float_t &phi3, Float_t beta) void SetVolumeParameters(Float_t sizeX, Float_t sizeY, Float_t sizeZ, BrVector3D origin, BrRotMatrix rotMatrix) Alternate volume parameter setting routine. More modern KH 4-May-2001 Convenient to use with MySQL mode of DB after calling name, title constructor ListParameters() 2/22/02 - Slated to become obsolete - use Print() instead ReadASCIIFile(const Char_t *ASCIIFileName, const Char_t *DetectorName) void GlobalToLocal(const float* xg, float* xl, int flag) void GlobalToLocal(const BrVector3D& xg, BrVector3D& xl, int flag) BrLine3D GlobalToLocal(const BrLine3D& line) void LocalToGlobal(const float xl[3], float xg[3],int flag) void LocalToGlobal(const BrVector3D& xl, BrVector3D& xg,int flag) flag = 1 transform direction cosines flag = 0 transform coordinates BrLine3D LocalToGlobal(const BrLine3D& line) GetPosVector3D() Return volume position as a vector GetPosition() Return volume position as a vector GetFrontPlane() Get the Front Plane of the detector in the Master Coordinate system GetBackPlane() Return Back in Master Coordinate system. GetMidPlane() Return MidPlane in Master Coordinate system. void Print(Option_t* option) const Options: B Basic information D Detector information void Update() Update the geometry parameters to those of the run currently selected. Do it only if a new run is being selected. Not necessary to do it if this is being called for the same run as it was the last time through. Bool_t FillVolume() Fill the detector volume from entries in MySQL database. By convention, we store the volume parameters in the DB in coordinates of the volume (platform) they are sitting on. In addition, the name of the parent volume (platform volume is placed on) is specified. To fill the BrDetectorVolume with global values, we start with the volume name, continue to get other volumes out specified by parent volume name until we reach the CAVE volume. This is recognized by having a parent volume with a length of 0. After each volume is extracted from the DB, the coordinates are translated into the master system of the parent volume and the rotation matrix is convoluted with the existing rotation matrix. Once this is done, the parameters are used to fill vol Return status: kTRUE if volume found and successfully filled kFALSE if volume not found or not successfully filled BrDbDetectorVolume* GetDetectorVolumeWithCondition(const Char_t *name,Float_t specAngle,Int_t platformType) Get detector volumes out of the DB with name like one specified and valid time less than run time. Then search through and find the one valid at the latest time which is earlier than the current run. We do that by looking for the smallest difference between the start of validity and the run time.
