Abstract: This paper shows the use of web resources to create environments for visualizing self-intersecting truncated polyhedra and their respective duals. These environments were created using Virtual Reality (VR) resources, which allow the visitor to manipulate the polyhedra and compare the polyhedra and their duals. Geometric transformations of homothety (scale), translation and rotation were used to build the virtual rooms, using HTML page hierarchies structures, and inserting each polyhedron in its respective virtual room. The resources presented in this work can be used in the classroom to visualize polyhedra with immersive goggles and even in Augmented Reality (AR) using smartphones and tablets.........
Keywords: virtual reality; self-intersecting truncated polyhedra; augmented reality; duality; geometry.
