[vtkusers] Montege 4X4 of some 3D Volume's slices

[Eric E. Monson]

Hey Daniela,

I guess I would suggest a different possibility. For each slice, you could set up a vtkImageReslice filter, and each one can go through a vtkImageMapToColors and then to a vtkImageActor. For each actor you can then use the SetPosition() method to arrange them in the 4x4 grid of images. Then, if you want to change the slices that are displayed, you just change the matrix that sets the "reslice axes" for that particular image. 

This method is taken directly from the ImageSlicing.cxx example in [vtk_source]/Examples/ImageProcessing/Cxx (or there are Python and Tcl examples of the same code in their respective subdirectories).

Talk to you later,
-Eric
