class TGeoTrap: public TGeoArb8

 TGeoArb8 - a arbitrary trapezoid with less than 8 vertices standing on
   two paralel planes perpendicular to Z axis. Parameters :
            - dz - half length in Z;
            - xy[8][2] - vector of (x,y) coordinates of vertices
               - first four points (xy[i][j], i<4, j<2) are the (x,y)
                 coordinates of the vertices sitting on the -dz plane;
               - last four points (xy[i][j], i>=4, j<2) are the (x,y)
                 coordinates of the vertices sitting on the +dz plane;
   The order of defining the vertices of an arb8 is the following :
      - point 0 is connected with points 1,3,4
      - point 1 is connected with points 0,2,5
      - point 2 is connected with points 1,3,6
      - point 3 is connected with points 0,2,7
      - point 4 is connected with points 0,5,7
      - point 5 is connected with points 1,4,6
      - point 6 is connected with points 2,5,7
      - point 7 is connected with points 3,4,6
   Points can be identical in order to create shapes with less than
   8 vertices.

TGeoTrap(const TGeoTrap& )
 Default ctor
TGeoTrap(Double_t dz, Double_t theta, Double_t phi)
 Constructor providing just a range in Z, theta and phi.
TGeoTrap(Double_t dz, Double_t theta, Double_t phi, Double_t h1, Double_t bl1, Double_t tl1, Double_t alpha1, Double_t h2, Double_t bl2, Double_t tl2, Double_t alpha2)
 Normal constructor.
TGeoTrap(const char* name, Double_t dz, Double_t theta, Double_t phi, Double_t h1, Double_t bl1, Double_t tl1, Double_t alpha1, Double_t h2, Double_t bl2, Double_t tl2, Double_t alpha2)
 Constructor with name.
~TGeoTrap()
 destructor
Double_t DistFromInside(Double_t* point, Double_t* dir, Int_t iact = 1, Double_t step = TGeoShape::Big(), Double_t* safe = 0) const
 Compute distance from inside point to surface of the trapezoid
Double_t DistFromOutside(Double_t* point, Double_t* dir, Int_t iact = 1, Double_t step = TGeoShape::Big(), Double_t* safe = 0) const
 Compute distance from outside point to surface of the trapezoid
TGeoVolume * Divide(TGeoVolume* voldiv, const char* divname, Int_t iaxis, Int_t ndiv, Double_t start, Double_t step)
--- Divide this trapezoid shape belonging to volume "voldiv" into ndiv volumes
 called divname, from start position with the given step. Only Z divisions
 are supported. For Z divisions just return the pointer to the volume to be
 divided. In case a wrong division axis is supplied, returns pointer to
 volume that was divided.
TGeoShape * GetMakeRuntimeShape(TGeoShape* mother, TGeoMatrix* mat) const
 In case shape has some negative parameters, these have to be computed
 in order to fit the mother.
Double_t Safety(Double_t* point, Bool_t in = kTRUE) const
 Computes the closest distance from given point to this shape.
void SavePrimitive(ostream& out, Option_t* option = "")
 Save a primitive as a C++ statement(s) on output stream "out".
void SetDimensions(Double_t* param)
 Set all arb8 params in one step.
 param[0] = dz
 param[1] = theta
 param[2] = phi
 param[3] = h1
 param[4] = bl1
