[vtkusers] Visualize .mha MRI volume

[Aashish Chaudhary]

Hi Megha,

You can look at this example to help with your task (
http://www.vtk.org/gitweb?p=VTK.git;a=blob;f=Examples/VolumeRendering/Cxx/GPURenderDemo.cxx).
In that example you can use vtkGPUVolumeRayCastMapper instead of
vtkSmartVolumeMapper
to simplify things a bit.

As fas the reader goes, how did you confirm that you only got one slice?

Thanks,
