_____________________________________________________________________________
TGeoTorus - Torus segment class. A torus has 5 parameters :
R - axial radius
Rmin - inner radius
Rmax - outer radius
Phi1 - starting phi
Dphi - phi extent
_____________________________________________________________________________
TGeoTorus(Double_t *param)
Constructor based on an array of parameters.
param[0] = R
param[1] = Rmin
param[2] = Rmax
param[3] = Phi1
param[4] = Dphi
void GetBoundingCylinder(Double_t *param)
--- Fill vector param[4] with the bounding cylinder parameters. The order
is the following : Rmin, Rmax, Phi1, Phi2, dZ
Double_t Safety(Double_t *point, Bool_t in)
computes the closest distance from given point to this shape, according
to option. The matching point on the shape is stored in spoint.
Double_t ToBoundary(Double_t *pt, Double_t *dir, Double_t r)
Returns distance to the surface or the torus (fR,r) from a point, along
a direction. Point is close enough to the boundary so that the distance
to the torus is decreasing while moving along the given direction.
