This paper discusses the production of visually appealing computer-generated images, through the emulation of human drawing techniques and artificial evolution. Employing a database of line drawn objects from user-input, the Darwinian process of evolution produces original compositions with increasing levels of user sat-

Via a computer search, Altshuler and Steinberg found that there are 1296 + 1 combinatorial 3-manifolds on nine vertices, of which only one is non-sphere. This exceptional 3-manifold K 9 triangulates the twisted S -bundle over S . It was first constructed by Walkup. In this paper, we present a computer-free proof of the uniqueness of this non-sphere combinatorial 3-manifold. As opposed to the co...

1.0 INTRODUCTION The existence of a universal aesthetic preference has long been a topic of debate. Several years ago, thinking about generative art, I realised that it would be possible to evolve pictures according to the viewer’s personal preference. I also realised that the resulting pictures, if taken from a wide variety of people, might indicate some kind of universal aesthetic preference....

We study gas diffusion through computer-generated random fibre networks using random walk simulations. The simulation results are consistent with steady-state experiments. The comparison of the simulated time-dependent diffusion flux with one-dimensional diffusion theory suggests that the latter is invalid at low porosities and low thicknesses. We also find that, if sorption is relevant, steady...

In an earlier paper we studied real laminated lattices (or Z-modules) A„, where A, is the lattice of even integers, and A„ is obtained by stacking layers of a suitable (n — l)-dimensional lattice A„_, as densely as possible, keeping the same minimal norm. The present paper considers two generalizations: (a) complex and quaternionic lattices, obtained by replacing Z-module by /-module, where J m...

New technological tools are allowing the authorship of computer-generated faces that can easily move between very realistic, to cartoon-like, to painterly or even iconified -in both depiction and movement. These systems are beginning to allow artists, scientists and scholars to explore the notion of “face space”, whether as a realistic emotive character, an artistic portrait or symbolic facial ...

This project aims at the realization of a wearable supervision system for chemical installations based on the augmented reality paradigm. Augmented reality improves the perception the operator has of his surrounding environment by overlaying real-time computer-generated images onto the real world. This document describes the work realized from the beginning of this year. The first step was to i...

This paper is motivated by the computer-generated nonadditive code described in Rains et al [RHSN97]. We describe a theory of non-stabilizer codes of which the nonadditive code of Rains et al is an example. Furthermore, we give a general strategy of constructing good nonstabilizer codes from good stabilizer codes and give some explicit constructions and asymptotically good nonstabilizer codes. ...

The topic of skeletal animation and its associated techniques have previously been applied in the area of animating computer-generated characters for motion pictures and computer games. This paper investigates the use of similar techniques in the scope of exploring three-dimensional visualisations of graphs. A system is discussed which, after generating an initial 3D layout for a graph, creates...

Previous research illustrates that people can be influenced by the emotional displays of computer-generated agents. What is less clear is if these influences arise from cognitive or affective process (i.e., do people use agent displays as information or do they provoke user emotions). To unpack these processes, we examine the decisions and physiological reactions of participants (heart rate and...
