Take a Stroll in Another World

Another World II is a print by the famous Dutch artist M. C. Escher, depicting a cube with arch-like openings on each side. What makes the print interesting is that the depicted views in the arches are inconsistent, leaving the spectator puzzled as to the “impossible assembly” of views from different perspectives. In our work we invite the reader – and more so, the user of our software – to explore the strange geometry of this work by flying through a virtual Another World. The rendering of the inconsistent views is achieved by applying Portal Rendering. We point out the novelty of our work with respect to previous 3D computer models of different “impossible worlds” by M. C. Escher. We also suggest potential application contexts beyond the straightforward 3D reconstruction of Another World
