Class Description


TGeoSphere()
 Default constructor

TGeoSphere(Double_t rmin, Double_t rmax, Double_t theta1, Double_t theta2, Double_t phi1, Double_t phi2) :TGeoBBox(0, 0, 0)
 Default constructor specifying minimum and maximum radius

TGeoSphere(const char *name, Double_t rmin, Double_t rmax, Double_t theta1, Double_t theta2, Double_t phi1, Double_t phi2) :TGeoBBox(name, 0, 0, 0)
 Default constructor specifying minimum and maximum radius

TGeoSphere(Double_t *param, Int_t nparam)
 Default constructor specifying minimum and maximum radius
 param[0] = Rmin
 param[1] = Rmax

~TGeoSphere()
 destructor

void ComputeBBox()
 compute bounding box of the sphere
   Double_t xmin, xmax, ymin, ymax, zmin, zmax;

Bool_t Contains(Double_t *point) const
 test if point is inside this sphere
 check Rmin<=R<=Rmax

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.
