[vtkusers] Volume Rendering

[lappadj at libero.it]

Hi John,thank for your interest,but with this code i can't read the bmp 
image,i receive error in SetFilePattern("pat.%d").And i must specify 
the SetFilePrefix?To solve this problem is very important for me 
because is the only problem with vtk.

Thanks a lot

Massimiliano
