[vtkusers] MIP Volume Rendering

[E.R]

Many thanks for your response.

I used, as you told me, Mesa classes (as in your code) and the window to image filter! 
I noticed that, its return a vtkImageData with 8bit values, although my images are 16bit! How can I avoid this 16bit to 8bit transform? I just want a 16bit vtkImageData, like my originals. 

Your answer will be precious.
