[Paraview] slice as background image?

[Armin Wehrfritz]

The "Camera parallel projection" is an advanced property and hence
hidden. You can find it by using the search or by toggling the advanced
properties (i.e. the small button with the wheel beside the search box).

Check the "Camera Parallel Projection" checkbox under the View properties panel. As long as your view direction is orthogonal to the slice plane, the streamlines will appear in the correct position relative to the slice plane after you translate one or the other.

The problem is that the slice and the streamlines are overlapping, and part of the streamlines are covered by the slice. I cannot change the origins of slice or streamlines in order to move them slightly forward or backward, because that would make me lose details of what I want to see. When I use the transform filter to translate the slice, I get a mismatch due to the perspective rendering.
