Class Description


TGeoTrd2()
 dummy ctor

TGeoTrd2(Double_t dx1, Double_t dx2, Double_t dy1, Double_t dy2, Double_t dz) :TGeoBBox(0,0,0)
 constructor.

TGeoTrd2(const char * name, Double_t dx1, Double_t dx2, Double_t dy1, Double_t dy2, Double_t dz) :TGeoBBox(name, 0,0,0)
 constructor.

TGeoTrd2(Double_t *param) :TGeoBBox(0,0,0)
 ctor with an array of parameters
 param[0] = dx1
 param[1] = dx2
 param[2] = dy1
 param[3] = dy2
 param[4] = dz

~TGeoTrd2()
 destructor

void ComputeBBox()
 compute bounding box for a trd2

Bool_t Contains(Double_t *point) const
 test if point is inside this shape
 check Z range

Double_t DistToOut(Double_t *point, Double_t *dir, Int_t iact, Double_t step, Double_t *safe) const
 compute distance from inside point to surface of the trd2

Double_t DistToIn(Double_t *point, Double_t *dir, Int_t iact, Double_t step, Double_t *safe) const
 compute distance from outside point to surface of the trd2

Double_t DistToSurf(Double_t * /*point*/, Double_t * /*dir*/) const
 computes the distance to next surface of the sphere along a ray
 starting from given point to the given direction.

Double_t GetAxisRange(Int_t iaxis, Double_t &xlo, Double_t &xhi) const
 Get range of shape for a given axis.

void GetVisibleCorner(Double_t *point, Double_t *vertex, Double_t *normals) const
 get the most visible corner from outside point and the normals

void GetOppositeCorner(Double_t * /*point*/, Int_t inorm, Double_t *vertex, Double_t *normals) const
 get the opposite corner of the intersected face

TGeoVolume* Divide(TGeoVolume *voldiv, const char *divname, Int_t iaxis, Int_t ndiv, Double_t start, Double_t step)
--- Divide this trd2 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.

void GetBoundingCylinder(Double_t *param) const
--- Fill vector param[4] with the bounding cylinder parameters. The order
 is the following : Rmin, Rmax, Phi1, Phi2

TGeoShape* GetMakeRuntimeShape(TGeoShape *mother) const
 in case shape has some negative parameters, these has to be computed
 in order to fit the mother

void InspectShape() const
 print shape parameters

void NextCrossing(TGeoParamCurve * /*c*/, Double_t * /*point*/) const
 computes next intersection point of curve c with this shape

Double_t Safety(Double_t *point, Bool_t in) const
 computes the closest distance from given point to this shape, according
 to option. The matching point on the shape is stored in spoint.

void SetDimensions(Double_t *param)
 set arb8 params in one step :

void SetPoints(Double_t *buff) const
 create trd2 mesh points

void SetPoints(Float_t *buff) const
 create trd2 mesh points

void SetVertex(Double_t *vertex) const
 set vertex of a corner according to visibility flags

void Sizeof3D() const
 fill size of this 3-D object
