 Default constructor specifying minimum and maximum radius

TGeoPara(const char *name, Double_t dx, Double_t dy, Double_t dz, Double_t alpha, Double_t theta, Double_t phi) :TGeoBBox(name, 0, 0, 0)
 Default constructor specifying minimum and maximum radius

TGeoPara(Double_t *param)
 Default constructor
 param[0] = dx
 param[1] = dy
 param[2] = dz
 param[3] = alpha
 param[4] = theta
 param[5] = phi

~TGeoPara()
 destructor

void ComputeBBox()
 compute bounding box

Bool_t Contains(Double_t *point) const
 test if point is inside this sphere
 test 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 para

Double_t DistToIn(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 para
   Warning("DistToIn", "PARA TOIN");
   Double_t snxt=kBig;

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)
--- Divide this paralelipiped shape belonging to volume "voldiv" into ndiv equal volumes
 called divname, from start position with the given step. Returns pointer
 to created division cell volume. In case a wrong division axis is supplied,
 returns pointer to volume to be divided.

TGeoVolume* Divide(TGeoVolume *voldiv, const char *divname, Int_t iaxis, Double_t step)
 Divide all range of iaxis in range/step cells

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, 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 SetPoints(Double_t *buff) const
 create sphere mesh points

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

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