[vtkusers] Question about what SetSlice() does from ImageViewer2

[Tina Zhang]

Hey,

In the documentation, it says that a call to SetSlice() changes the slice
displayed and the "depth of the displayed slice in the 3d scene." I was
wondering about what exactly that means.

I'm displaying DICOM images and I have a slider that lets the user go
through all the images but it seems like the camera stays put and, since
each slice is at a difference z-coordinate (I assume), the image "appears"
to get bigger. How do I counteract that?
