[Paraview] adding source to VTK (or any other format) file

[Rick Wagner]

Hi Battalgazi,

I think what you're looking for is vtkGlyph3D. Using a set of points  
with scalar values associated with them, you can display spheres and  
other items easily. Check out the tutorial at:
   http://www.psc.edu/general/software/packages/paraview/tutorial/ 
pvt.php

If you need to generate datasets, I recommend using PolyData, and you  
can find many good examples on how to do that in the VTK documentation.
