Class Description

 PolyMarker3D is a 3D polymarker. It has three constructors.

   First one, without any parameters TPolyMarker3D(), we call 'default
 constructor' and it's used in a case that just an initialisation is
 needed (i.e. pointer declaration).

       Example:
                 TPolyMarker3D *pm = new TPolyMarker3D;


   Second one, takes, usually, two parameters, n (number of points) and
 marker (marker style). Third parameter is optional.

       Example:
                 TPolyMarker3D (150, 1);


   Third one takes, usually, three parameters, n (number of points), *p
 (pointer to an array of 3D points), and marker (marker style). Fourth
 parameter is optional.

       Example:
                 Float_t *ptr = new Float_t [150*3];
                         ... ... ...
                         ... ... ...
                         ... ... ...

                 TPolyMarker3D (150, ptr, 1);



TPolyMarker3D()
 3-D polymarker default constructor.

TPolyMarker3D(Int_t n, Marker_t marker, Option_t *option)
 3-D polymarker normal constructor with initialization to 0.

TPolyMarker3D(Int_t n, Float_t *p, Marker_t marker, Option_t *option)
 3-D polymarker constructor. Polymarker is initialized with p.

TPolyMarker3D(Int_t n, Double_t *p, Marker_t marker, Option_t *option)
 3-D polymarker constructor. Polymarker is initialized with p
 (cast to float).

~TPolyMarker3D()
 3-D polymarker destructor.

TPolyMarker3D(const TPolyMarker3D &polymarker)
 3-D polymarker copy ctor.

void Copy(TObject &obj)
 Copy polymarker to polymarker obj.

Int_t DistancetoPrimitive(Int_t px, Int_t py)
 Compute distance from point px,py to a 3-D polymarker.
 Compute the closest distance of approach from point px,py to each segment
 of the polymarker.
 Returns when the distance found is below DistanceMaximum.
 The distance is computed in pixels units.

void Draw(Option_t *option)
 Draws 3-D polymarker with its current attributes.

void DrawPolyMarker(Int_t n, Float_t *p, Marker_t, Option_t *option)
 Draw this 3-D polymartker with new coordinates. Creates a new
 polymarker which will be adopted by the pad in which it is drawn.
 Does not change the original polymarker (should be static method).

void ExecuteEvent(Int_t event, Int_t px, Int_t py)
 Execute action corresponding to one event.

void ls(Option_t *option) const
 List this 3-D polymarker.

void Paint(Option_t *option)
 Paint this 3-D polymarker.
 Option could be 'x3d', and it means that output
 will be performed by X3D package.

void PaintH3(TH1 *h, Option_t *option)
 Paint 3-d histogram h with 3-d polymarkers.

void PaintPolyMarker(Int_t n, Float_t *p, Marker_t, Option_t *)
 Paint 3-D polymarker with new coordinates from p. Does not change
 original polyline. Should be static method.

void Print(Option_t *option) const
 Print 3-D polymarker with its attributes on stdout.

void SavePrimitive(ofstream &out, Option_t *)
 Save primitive as a C++ statement(s) on output stream.

Int_t SetNextPoint(Double_t x, Double_t y, Double_t z)
 Set point following LastPoint to x, y, z.
 Returns index of the point (new last point).

void SetPoint(Int_t n, Double_t x, Double_t y, Double_t z)
 Set point n to x, y, z.
 If n is more then the current TPolyMarker3D size (n > fN) then
 the polymarker will be resized to contain at least n points.

void SetPolyMarker(Int_t n, Float_t *p, Marker_t marker, Option_t *option)
 Re-initialize polymarker with n points from p. If p=0 initialize with 0.

void SetPolyMarker(Int_t n, Double_t *p, Marker_t marker, Option_t *option)
 Re-initialize polymarker with n points from p. If p=0 initialize with 0.

void Sizeof3D() const
 Return total size of this 3-D polymarker with its attributes.

void SizeofH3(TH1 *h)
 Return total size of 3-D histogram h.

void Streamer(TBuffer &b)
 Stream a 3-D polymarker object.
