[vtkusers] volume rendering of TIFF images

[Lisa Sobierajski Avila]

Hello André,

VTK can only volume render single component images. I suspect yours has 
three components (check the number of scalar components in your output of 
the reader) and that's why you are seeing multiple copies of your data. Try 
passing the output of your reader through a luminance filter.
