[vtkusers] tile of renderers

[José M. Rodriguez Bacallao]

well, I know that I could have a list of renderers, the problem is
that I don't know how to select an specific slice for that renderer
from a 3D vtkImageData and if there is a simple way of synchrionizing
all the renderers when I change from one slice to another.

answering your question about achieving other orientations with
ViewUp, well, right now I can achieve axial, coronal and sagital
orientations using methods from vtkInteractorStyleImage, for example:

        style = vtk.vtkInteractorStyleImage()
        style.SetInteractionModeToImageSlicing()
        style.SetZViewRightVector((1, 0, 0))
        style.SetZViewUpVector((0, -1, 0))
        style.SetXViewRightVector((0, 1, 0))
        style.SetXViewUpVector((0, 0, 1))
        style.SetYViewRightVector((1, 0, 0))
        style.SetYViewUpVector((0, 0, 1))

this are my vectors when I am reading dicom images with gdcm and it's
original orientations (the reader is not flipping images)
I don't now if I can achieve other orientations using this methods but
I think that if you user vtkImageResliceMapper or vtkImageSlice you
can do it.
