[vtkusers] getting a blank volume when trying to perform an x-ray projection in Java

[Mark Roden]

Hi David,

Thanks for this-- I'll take a look.  I definitely need the ability to
rotate freely, so having to write my own controller over the reslice
could be extremely painful.

What kinds of projections?  I really want an average intensity
projection, but I can't really see how to do that now.

Thanks,
Mark
