Distortions and Displacements in 2D

Distortions are a common means to present complex information in an expressive and easily comprehensible way. To enhance the viewer’s perception, one or more areas of interest to the viewer are emphasized — they are brought to the focus. Typically, the areas lying in the focus are enlarged at the expense of their surroundings; they can be shown with more detail. Hence, distortion is a way to cope with the limited space of a presentation area, in general the screen or a sheet of paper.
