A vtkPoint is a geometric location. You need cells to visualize your data.<br>
in your case, you need Vert's, one for each Point. An easy way to create<br>
the verts is to use vtkVertexGlyphFilter.<br>
<br>
See for example:<br>

i need to ask the line by line documentation of this function, how these<br>
points and surface is formed?<br>

><br>
> Note that my VTK application is also consuming a lot of memory and CPU,<br>
