Take a look at vtkImageReslice. Here's how you might set it up:

vtkImageReslice volReslice
volReslice SetInput [volumeReader GetOutput]
volReslice SetOutputOrigin 0 0 0
volReslice SetOutputSpacing 1 1 1
volReslice SetOutputExtent \
    0 [expr $gWindowSize - 1] \
    0 [expr $gWindowSize - 1] \
    0 [expr $gWindowSize - 1]
volReslice SetResliceAxesDirectionCosines \
    0 0 1 \
    0 1 0 \
    1 0 0
volReslice InterpolateOn
volReslice SetOutputDimensionality 3

SetResliceAxesDirectionConsines sets the direction in which the reslicer
reslices the volume. Then connect it to an image viewer:

imageViewer SetInput [volReslice GetOutput]
imageViewer SetZSlice 128
imageViewer SetColorWindow 200
imageViewer SetColorLevel 100

You can have a slider call:

imageViewer SetZSlice $newSlice

to change the slice interactively.
