[vtkusers] Slicing a volume defining angles using ImageReslice

[Luca]

Hi!
I have to slice a 3D volume in a oblique orientation.
I used the example: 
http://vtk.org/gitweb?p=VTK.git;a=blob;f=Examples/ImageProcessing/Cxx/ImageSlicing.cxx
I define the obliqueElements vector, but I have to slice the volume in 
x, y, z direction. So I have to defines 3 obliqueElements vectors, one 
for each rotation... How could I concatenate the three rotations?

Thanks so much!
