Abstract:
Ambiguous objects provide visual shape information that can be interpreted differently depending on the viewing direction. Generating effective ambiguity objects is difficult and therefore requires easy-to-use computational modelling. In this paper, we propose a Three-Dimensional (3D) modelling tool to generate an object that can be perceived differently from two different viewing directions. The tool uses solid models of cylindrical surfaces parallel to each of the viewing directions. These models are intersected at the central axis and rotated according to the viewing direction, using the intersection as the origin. Finally, by transforming each Two-Dimensional (2D) figure drawn by the user in each viewing direction into a cylindrical surface, a 3D ambiguous object can be generated. These 2D figures can be drawn using mouse click events. The generated ambiguous objects can be fabricated on a 3D printer to demonstrate the usability of the proposed tool. Our experiments show that ambiguous objects consisting of simple and complex shapes were successfully generated.
