Function documentation

Int_t Add(Float_t x, Float_t y, Float_t z)
 Add one 3D point defined by x,y,z to the array of the points
 as its last element
Int_t AddLast(Float_t x, Float_t y, Float_t z)
 Add one 3D point defined by x,y,z to the array of the points
 as its last element
Int_t DistancetoLine(Int_t px, Int_t py, Float_t x1, Float_t y1, Float_t x2, Float_t y2, Int_t lineWidth = 1)
 Compute distance from point px,py to an axis of the band defined.
  by pair points  (x1,y1),(x2,y2) where lineWidth is the width of the band

  Compute the closest distance of approach from point px,py to this line.
  The distance is computed in pixels units.


  Algorithm:

    A(x1,y1)         P                             B(x2,y2)

                     I
                     I
                     I
                     I
                    M(x,y)

  Let us call  a = distance AM     a2=a**2
               b = distance BM     b2=b**2
               c = distance AB     c2=c**2
               d = distance PM     d2=d**2
               u = distance AP     u2=u**2
               v = distance BP     v2=v**2     c = u + v

  d2 = a2 - u2
  d2 = b2 - v2  = b2 -(c-u)**2
     ==> u = (a2 -b2 +c2)/2c

   Float_t x1    = gPad->XtoAbsPixel(xp1);
   Float_t y1    = gPad->YtoAbsPixel(yp1);
   Float_t x2    = gPad->XtoAbsPixel(xp2);
   Float_t y2    = gPad->YtoAbsPixel(yp2);
Int_t SetNextPoint(Float_t x, Float_t y, Float_t z)
 Add one 3D point defined by x,y,z to the array of the points
 as its last element
Int_t GetN()
 GetN()  returns the number of allocated cells if any.
         GetN() > 0 shows how many cells
         can be available via GetP() method.
         GetN() == 0 then GetP() must return 0 as well
Float_t * GetP()
 GetP()  returns the pointer to the float point array
         of points if available
         The number of the available celss can be found via
         GetN() method.
         GetN() > 0 shows how many cells
Float_t * GetXYZ(Float_t* xyz, Int_t idx, Int_t num = 1) const
 GetXYZ(Float_t *xyz,Int_t idx,Int_t num=1) fills the buffer supplied
 by the calling code with the points information.

  Input parameters:

   Float_t *xyz - an external user supplied floating point array.
   Int_t    num - the total number of the points to be copied
                  the dimension of that array the size of the
                  array is num*sizeof(Float_t) at least
   Int_t    idx - The index of the first copy to be taken.

  Return: The pointer to the buffer array supplied
virtual ~TPoints3DABC()
{;}
Int_t DistancetoPrimitive(Int_t px, Int_t py)
Int_t GetLastPosition()
 GetN()  returns the number of allocated cells if any.
         GetN() > 0 shows how many cells
         can be available via GetP() method.
         GetN() == 0 then GetP() must return 0 as well
