Hi David,<div><br></div><div>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? : )</div>

This example creates a grid of X,Y points and adds a random Z<br>
component. There is no requirement for these points to be arranged in<br>
a grid.<br>

Take a look and let us know if that helps.<br>

Thanks,<br>
