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

Int_t DistancetoPrimitive(Int_t px, Int_t py)
 compute closest distance from point px,py to each corner

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 polycone

Double_t DistToSegZ(Double_t *point, Double_t *dir, Int_t &iz, Double_t c1, Double_t s1, Double_t c2, Double_t s2, Double_t cfio, Double_t sfio, Double_t cdfi) const

 starting from given point to the given direction.

void DefineSection(Int_t snum, Double_t z, Double_t rmin, Double_t rmax)
 defines z position of a section plane, rmin and rmax at this z.

Int_t GetNsegments() const

TGeoVolume* Divide(TGeoVolume *voldiv, const char *divname, Int_t iaxis, Int_t ndiv, Double_t start, Double_t step)
--- Divide this polycone shape belonging to volume "voldiv" into ndiv volumes
 called divname, from start position with the given step. Returns pointer
 to created division cell volume in case of Z divisions. Z divisions can be
 performed if the divided range is in between two consecutive Z planes.
  In case a wrong division axis is supplied, returns pointer to
 volume that was divided.
