I would suggest looking through some of the examples:

http://www.vtk.org/Wiki/VTK/Examples/Cxx/PolyData/TriangleColoredPoints

and you should always try to generate the situation you are having in the
smallest possible compilable, self contained code. That is, don't read a
file, generate data programmatically (vtkSphereSource, etc). Remove all
extraneous calls (you have a writer in the above code that doesn't seem
necessary).

Also, you should use smart pointers instead of normal pointers so you don't
need the giant block of Delete() calls at the bottom (it makes the code
longer and less appealing to look at for us at a glance).
