3D Realization of Penrose Polygons Using Non-Rectangularity Trick

This paper generalizes an impossible figure called a "Penrose triangle" to regular polygonal figures and proposes method for constructing real 3D objects from such figures. Two well-known tricks, namely the curved surface trick discontinuity trick, have been used construct However, these tricks are very sensitive viewpoint. The proposed uses only planar faces connects them wherever they appear be connected. resulting thus less viewpoint in sense that impression of impossibility does not disappear when slightly changes. Moreover, constructed same symmetry as original figures, preserving their elegance.
