 ctor

TGeoCtub(Double_t *params)
 ctor with parameters

~TGeoCtub()
 dtor

void ComputeBBox()
 compute minimum bounding box of the ctub

Bool_t Contains(Double_t *point) const
 check if point is contained in the cut tube
 check the lower cut plane

Double_t GetZcoord(Double_t xc, Double_t yc, Double_t zc) const
 compute real Z coordinate of a point belonging to either lower or
 higher caps (z should be either +fDz or -fDz)

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 cut tube

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 cut tube

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.

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

 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, Double_t *spoint, Option_t *option) 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 SetCtubDimensions(Double_t rmin, Double_t rmax, Double_t dz, Double_t phi1, Double_t phi2, Double_t lx, Double_t ly, Double_t lz, Double_t tx, Double_t ty, Double_t tz)
