Class Description


 Manages a detector rotation matrix. See class TGeometry.

TRotMatrix()
 RotMatrix default constructor.
TRotMatrix(const char *name, const char *title, Double_t *matrix)
 RotMatrix normal constructor.
TRotMatrix(const char *name, const char *title, Double_t theta, Double_t phi, Double_t psi)
 RotMatrix normal constructor.
TRotMatrix(const char *name, const char *title, Double_t theta1, Double_t phi1 , Double_t theta2, Double_t phi2 , Double_t theta3, Double_t phi3)
 RotMatrix normal constructor defined a la GEANT.

 The TRotMatrix constructor with six angles uses the GEANT convention:

 theta1 is the polar angle of the x-prim axis in the main reference system
 (MRS), theta2 and theta3 have the same meaning for the y-prim and z-prim
 axis.

 Phi1 is the azimuthal angle of the x-prim in the MRS and phi2 and phi3
 have the same meaning for y-prim and z-prim.


 for example, the unit matrix is defined in the following way.

     x-prim || x, y-prim || y, z-prim || z

     means:  theta1=90, theta2=90, theta3=0, phi1=0, phi2=90, phi3=0
~TRotMatrix()
 RotMatrix default destructor.
Double_t Determinant()
 Determinant() returns the value of the determiant of this matrix
Double_t* GetGLMatrix(Double_t *rGLMatrix)
  Convert this matrix to the OpenGL [4x4]

  [  fMatrix[0]   fMatrix[1]   fMatrix[2]    0  ]
  [  fMatrix[3]   fMatrix[4]   fMatrix[5]    0  ]
  [  fMatrix[6]   fMatrix[7]   fMatrix[8]    0  ]
  [     0             0           0          1  ]

  Input:
  -----
  Double_t *rGLMatrix - pointer to Double_t 4x4 buffer array

  Return:
  ------
  Double_t pointer to the input buffer
const Double_t* SetAngles(Double_t theta1, Double_t phi1, Double_t theta2, Double_t phi2,Double_t theta3, Double_t phi3)
 theta1 is the polar angle of the x-prim axis in the main reference system
 (MRS), theta2 and theta3 have the same meaning for the y-prim and z-prim
 axis.

 Phi1 is the azimuthal angle of the x-prim in the MRS and phi2 and phi3
 have the same meaning for y-prim and z-prim.


 for example, the unit matrix is defined in the following way.

     x-prim || x, y-prim || y, z-prim || z

     means:  theta1=90, theta2=90, theta3=0, phi1=0, phi2=90, phi3=0
void SetMatrix(const Double_t *matrix)
 copy predefined 3x3 matrix into TRotMatrix object
void SetReflection()
 SetReflection() -  checks whether the determinant of this
                    matrix defines the reflection transformation
                    and set the "reflection" flag if any
void Streamer(TBuffer &R__b)
 Stream an object of class TRotMatrix.
void SetName(const char *)
{ }
TRotMatrix()
Double_t* GetMatrix()
{return &fMatrix[0];}
Int_t GetNumber()
{return fNumber;}
Int_t GetType()
{return fType;}
Double_t GetTheta()
{return fTheta;}
Double_t GetPhi()
{return fPhi;}
Double_t GetPsi()
{return fPsi;}
Bool_t IsReflection()
{return TestBit(kReflection);}
