[vtkusers] How to create XYZ plot?

[董理]

Hi David,

Thank you for reply! But that example just creates vtkPolyData with
vtkPoints, there is no code for mapping and rendering~ I am new to VTK, just
get the general concept of VTK, but not quite familiar with the programming
details. Can you show me a more concrete example? : )
