Hi,

in the vtkImageViewer2 Class Reference ([https://vtk.org/doc/nightly/html/classvtkImageViewer2.html#details](https://vtk.org/doc/nightly/html/classvtkImageViewer2.html#details)) it is reported that “Any portions of your geometry that are in front of the displayed slice will be visible; any portions of your geometry that are behind the displayed slice will be obscured.”

Is there a way to avoid this behavior making every portion of the geometry visible, even when it is behind the displayed slice?

Thanks in advance.
