[vtkusers] Really need help on volume rendering!!

[Crystal Li]

Hi all,

I'm new to vtk, and recently I need to do the volume rendering on GPU for
some medical image DICOM data...
Attached is the code I checked the classes and I think should work...

But It cannot get any rendering output as I expected..
Could anyone help me with it?
Do the vtkDICOMImageReader() function can read the DICOM file properly in
vtk?

Thank you so so much!!!
Crystal
