Topology-Disturbing Objects: A New Class of 3D Optical Illusion
نویسنده
چکیده
A new class of objects, called topology-disturbing objects, is presented. These objects appear to disturb topological properties when they are seen from two specific viewpoints; for example, two objects appear to be separated when seen from one viewpoint while they appear to be intersecting when seen from the other viewpoint. This cannot happen physically, but due to the phenomenon of an optical illusion, it can be perceived to occur. A general method for designing this class of objects is presented and examples are given. These objects might provide a new resource for arts and entertainment.

Anomalous Mirror Symmetry Generated by Optical Illusion
This paper introduces a new concept of mirror symmetry, called “anomalous mirror symmetry”, which is physically impossible but can be perceived by human vision systems because of optical illusion. This symmetry is characterized geometrically and a method for creating cylindrical surfaces that create this symmetry is constructed. Examples of solid objects constructed by a 3D printer are also shown.
متن کامل3D Modelling of Under Ground Burried Objects Based on Ground Penetration Radar
There is a growing demand for mapping and 3D modelling of buried objects such as pipelines, agricultural hetitage, landmines and other buried objects. Usually, large scale and high resolution maps from these objects are needed. Manually map generation and modeling of these objects are cost and time consuming and is dependent on lots of resources. Therefore, automating the subsurface mapping and...
متن کاملمدلسازی روابط توپولوژیک سه بعدی فازی در محیط GIS
Nowadays, geospatial information systems (GIS) are widely used to solve different spatial problems based on various types of fundamental data: spatial, temporal, attribute and topological relations. Topological relations are the most important part of GIS which distinguish it from the other kinds of information technologies. One of the important mechanisms for representing topological relations...
متن کاملIllusion Media: Generate Virtual Objects Using Realizable Metamaterials
Transformation optics offers an unconventional strategy to the design of metamaterial devices. In this letter, we propose a class of optical transformation media, illusion media, which can render the enclosed object invisible and generate one or more virtual objects as desired. An arbitrary object enclosed by such an illusion medium layer appears to be one or more other objects. We apply the pr...
متن کاملA New Class of Resonant Discharge Drive Topology for Switched Reluctance Motor
Switched reluctance motor (SRM) drive has a remarkable characteristic, high efficiency, and good controllability, which makes it attractive for high-speed applications. In this paper, the basic control strategy for a switched reluctance motor drive circuit is explained and then three different resonant discharge topologies for SRM drive circuit are proposed. Due to resonantly discharging of exc...
