## Class Description

     SPHE is a Sphere. It has 9 parameters:

         - name       name of the shape
         - title      shape's title
         - material  (see TMaterial)
         - rmin       minimum radius
         - rmax       maximum radius
         - themin     theta min
         - themax     theta max
         - phimin     phi min
         - phimax     phi max

TSPHE()

     SPHE shape normal constructor

TSPHE(const char *name, const char *title, const char *material, Float_t rmax) : TShape(name, title,material)

     SPHE shape "simplified" constructor

~TSPHE()

     SPHE shape default destructor

Int_t DistancetoPrimitive(Int_t px, Int_t py)

     Compute distance from point px,py to a PSPHE

     Compute the closest distance of approach from point px,py to each

void SetEllipse(const Float_t *factors)

void SetNumberOfDivisions (Int_t p)

void SetPoints(Double_t *points) const

     Create SPHE points

void Sizeof3D() const

void MakeTableOfCoSin() const

void Streamer(TBuffer &b)

     Stream a class object
