void TGraph2DPainter::Paint ( Option_t * option )

virtual

Paint a TGraphDelaunay according to the value of "option":

Option	Description
"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.
