Function documentation

 TGraphPainter default constructor
TGraphPainter(TGraphDelaunay *gd)
 TGraphPainter constructor
 TGraphPainter destructor.
void FindTriangles()
 Find triangles in fDelaunay and initialise the TGraphPainter values
 needed to paint triangles or find contours.
TList * GetContourList(Double_t contour)
 Returns the X and Y graphs building a contour. A contour level may
 consist in several parts not connected to each other. This function
 finds them and returns them in a graphs' list.
void Paint(Option_t* option)
 Paint a TGraphDelaunay according to the value of "option":

   "TRI"  : The Delaunay triangles are drawn using filled area.
            An hidden surface drawing technique is used. The surface is
            painted with the current fill area color. The edges of each
            triangles are painted with the current line color.
   "TRIW" : The Delaunay triangles are drawn as wire frame
   "TRI1" : The Delaunay triangles are painted with color levels. The edges
            of each triangles are painted with the current line color.
   "TRI2" : the Delaunay triangles are painted with color levels.
   "P"    : Draw a marker at each vertex
   "P0"   : Draw a circle at each vertex. Each circle background is white.
   "PCOL" : Draw a marker at each vertex. The color of each marker is
            defined according to its Z position.
   "CONT" : Draw contours
   "LINE" : Draw a 3D polyline
void PaintContour(Option_t* option)
 Paints the 2D graph as a contour plot. Delaunay triangles are used
 to compute the contours.
void PaintLevels(Int_t* T, Double_t* x, Double_t* y, Int_t nblev = 0, Double_t* glev = 0)
 Paints one triangle.
 nblev  = 0 : paint the color levels
 nblev != 0 : paint the grid
void PaintPolyMarker(Option_t* option)
 Paints the 2D graph as PaintPolyMarker
void PaintPolyLine(Option_t* option)
 Paints the 2D graph as PaintPolyLine
void PaintPolyMarker0(Int_t n, Double_t* x, Double_t* y)
 Paints a circle at each vertex. Each circle background is white.
void PaintTriangles(Option_t* option)
 Paints the 2D graph as triangles
