[vtkusers] How to write triangle strip into file

[Łukasz Tutaj]

Hi vtkUsers

I'm interesting in the best way of writing triangle strip into file. 
Which class should I use?? It is also important for me to know how the 
data is organised in the file, because I have to read it without using 
vtk, because I want to visualize this data using DirectX (vtk isn't good 
enough for my project).
Thanks for any help.
