Method on mglGraph: void TriPlot (const mglData &id, const mglData &x, const mglData &y, const mglData &z, const char *sch=NULL): The function draws the surface of triangles. Triangle vertexes are set by indexes id of data points {x[i], y[i], z[i]}. String sch sets the color scheme. Previous color scheme is used by default. If string contain ‘#’ then wire plot is produced. First dimensions of id must be 3 or greater. Arrays x, y, z must have equal sizes. See also Dots, Crust.

Method on mglGraph: void TriPlot (const mglData &id, const mglData &x, const mglData &y, const char *sch=NULL, float zVal=NAN): The same as previous with z[i]=zVal.
