    Implementing the continuous staircase illusion in OpenGL

Session/Category Title:   Geometric Modeling



    The inspiration for the project described in this sketch was certainly the M. C. Escher lithograph ASCENDING AND DESCENDING. An image of this drawing can be seen at http://www.worldofescher.com/gallery. It is based on the continuous staircase illusion of L. S. and Roger Penrose and depicts a three-dimensional scene that appears to have properties that contradict what is possible in an actual Cartesian representation of spatial objects. The goal of this project was to add animation and a navigable viewpoint to this illusion by using the three-dimensional environment of OpenGL.
