class HGeomTransform: public TObject

_HADES_CLASS_DESCRIPTION


 HGeomTransform

 Class to hold the orientation (rotation matrix) and the position
 (translation vector) of a coordinate system (system 2) relative to a
 reference coordinate system (system 1)
 It provides member functions to transform a vector or a point and an other
 coordinate system from its own coordinate system into the reference
 coordinate system and vice versa.
 Instances of this class can e.g. hold the lab or detector transformation of
 a geometry volume (see class HGeomVolume)

 Inline functions:

 HGeomTransform()

 HGeomTransform(HGeomTransform& t)
    copy constructor
 void setTransform(const HGeomTransform& t)

 void setRotMatrix(const HGeomRotation& r)
    copies the given rotation matrix
 void setRotMatrix(const Double_t* a)
    creates a rotation matrix taking an Double_t array with 9 components
 void setTransVector(const HGeomVector& t)
    copies the given translation vector
 void setTransVector(const Double_t* a)
    creates a translation vector taking an Double_t array with 6 components
 const HGeomRotation& getRotMatrix() const
    returns the rotation matrix
 const HGeomVector& getTransVector() const
    returns the  translation vector

Function documentation

HGeomTransform& operator=(const HGeomTransform& t)
HGeomVector transFrom(const HGeomVector& p)
 Transforms a vector (point) given in its own coordinate
 system (2) into the reference coordinate system (1)
 e.g. v2 is a vector (point) in the detector coordinate system;
 it can be transformed to a vector v2 the lab system with
    HGeomVector v2=mo.transFrom(v1)
 where mo is the coordinate system of the mother
HGeomVector transTo(const HGeomVector& p)
 Transforms a vector (point) given in the reference system (1)
 into the local coordinate system (2)
 e.g. v1 is a vector (point) in the lab system; it can be transformed to
 a vector v2 the detector coordinate system with
    HGeomVector v2=mo.transTo(v1)
 where mo is the coordinate system of the mother
void transTo(const HGeomTransform& s)
 Transforms the coordinate system into the coordinate system
 described by s. Both transformations must have the same reference
 system e.g. the lab system
 This function is e.g. used to transform a daughter coordinate system
 with a transformation relative to the lab into the detector coordinate
 system.
void transFrom(const HGeomTransform& s)
 Transforms the coordinate system described by s into the local
 coordinate system
 This function is e.g. used to transform a daughter coordinate system
 with a transformation relative to its mother into the lab system.
 e.g. daughterDetTransform.transFrom(motherLabTransform)
