ListSurfacePlot3d

Question

I am trying to plot a surface plot, but the surface plot is empty. It does show the frame of the plot if I plot with ListPointPlot3D, but not with ListSurfacePlot3D.

How can I make this data into a surface plot?

v = Table[Table[{xgrid[[i]], xgrid[[j]], u[[i*j]]}, {i, 1,Length[xgrid]}], {j, 1, Length[xgrid]}];

ListPointPlot3D[v, ViewPoint -> {0, -2, 0}] /. Point -> Line
ListSurfacePlot3D[v, PlotRange -> All]
ListPlot3D[v, Mesh -> All]

Here is ListPointPlot3D:

Answer 1

The structure of your table is wrong. Look at the nesting of the lists. For ListPlot3D or ListSurfacePlot3D, you need v to be of the form {{x1,y1,z1},{x2,y2,z2},...}.

Try

v2=Partition[Flatten[v],3]

and then do ListPlot3D or ListSurfacePlot3D on v2.
