For a long time, some classic two-dimensional impossible figures have been known, which are also frequently used in design / art. Example are the works of M. C. Escher. - But how to implement 3D-impossible figures? Is it possible to find a solution by modeling and rendering in 3D software?

Camera View
Before modeling the correct camera view must be determined. Usually, you need to model with one axonometric projection view, such as the isometric view. In CINEMA 4D there are different camera views that are appropriate for different figures.

Modeling Techniques
After trying to build many 3D models of the various impossible figures, I summarized four main modeling techniques.

Cut
Cover

Shade
Separate
Combination
When modeling some impossible figures two or more methods need to be combined.

Cut + Shade
Alternative
When modelling some impossible figures there is not only one method.
