[vtkusers] vtk volume rendering

[Crystal Li]

Hi all,

I want to do the volume rendering for nifti files (.nii)..
I use the following to read an .nii file:

from nifti import NiftiImage
data_set="/home-nfs/local/pythonGPUdata/test/KKI2009-01-DTI.nii"
nim = NiftiImage(data_set)
img_data=nim.data
img=vtkImageImportFromArray()
img.SetArray(img_data)


Is this the correct way to read nifti file in vtk?
When I run the render in this way, there is always a "segmentation fault"
while rendering....

Do anyone have the similar experience?

Any help is appreciated!!
Thank you very much!
Crystal
