Computer graphics makes it easy to transform one object into another. This well-known "morphing" is often used for film effects. Here is an example of geometry: the transformation of a sphere into a torus.

German translation of caption:

Mit den Mitteln der Computergrafik ist es leicht, Ojekte in andere zu verwandeln - eine als 'Morphing' gut bekannte und für Filmeffekte oft verwendete Methode. Hier ein Beispiel aus der Geometrie: die Verwandlung einer Kugel in einen Torus.

By experimenting with geometric morphing, you will often find aesthetically interesting intermediate stages. The resulting graphics are examples of a remarkable type of computer art known as "virtual sculptures", which you can display realistically even if it would be impossible in physical reality.
