View Direction
The Region of Interest (ROI), also referred to as the Render Box in rendering, contains the section of
the volume you want to render. Therefore, objects that are not inside the box are not included in the
render process and are cut out (this is important in surface mode to allow a free line of sight). This may
or may not be the entire VOI.
You can adjust the view direction of the ROI.
