Harness is an experimental metacomputing system based upon the principle of dynamic reconfigurability both in terms of the computers and networks that comprise the virtual machine, and in the services offered by the virtual machine itself. In this paper we describe how the capability to reconfigure the virtual machine plugging services on demand can be exploited to design dynamically reconfigur...

—While the animation and rendering techniques used in the domain of textile simulation have dramatically evolved during the last two decades, the ability to manipulate and modify virtual textiles intuitively using dedicated ergonomic devices has been definitely neglected. The project HAPTEX combines research in the field of textile simulation and haptic interfaces. HAPTEX aims to provide a virt...

Virtual microscopy may be defined as the simulation of microscopy, over a computer network, as opposed to real microscopy using a physical microscope. The term ‘‘microscopy’’ is derived from Greek roots: ‘‘mikros’’ (small) and ’’skopeo’’ (to view). A technical definition for the term ‘‘virtual’’ is a ‘‘simulation of the real thing’’ [1]. Synonyms for virtual microscopy include digital microscop...

Virtual environment induces simulator sickness effect for some users. The purpose of this research is to compare the simulation sickness relative with parallax affect in one-screen and three-screen HoloStage system, measured by Simulation Sickness Questionnaire (SSQ). The results show the subjects tested in three-screen has less sickness than one-screen and effect from the Oculomotor (O) more t...

This paper presents a traffic simulation system based on multi-agent animation method. The behaviour model of individual virtual agent defines the driving characteristics of the vehicle agent and cell-based configurations allow real-time dynamic path planning and efficient traffic flow simulations. By incorporating the advantages of discrete cellular automation algorithms and the continuous mod...

Research areas that require interactive visualization of simulation data tend to dismiss virtual reality due to the lack of accessible tools for application specialists. This paper presents an integral toolkit for interactive visualization in virtual reality environments. The toolkit defines a framework to build applications that allow the user to interact with arbitrary simulation software and...

Networked haptic virtual environments were increasingly being used in medical simulation, aircraft maintenance training etc. The authors previously proposed virtual coupling schemes for NHVE’s and tested it for constant delay simulated by buffers. They are currently working on a time varying delay simulation of the virtual coupling schemes. Here the authors present the implementation of network...

Currently there is a tendency to integrate Virtual Reality characteristics and production processes models. This tendency is leading to the creation of the next generation simulation systems that will provide quantitative data for the process, increased visualization, fly through and interaction capabilities in a virtual environment. This review aims at clarifying the technologies involved in t...

R apid change is under way on several fronts in medicine and surgery. Advances in computing power have enabled continued growth in virtual reality, visualization, and simulation technologies. The ideal learning opportunities afforded by simulated and virtual environments have prompted their exploration as learning modalities for surgical education and training. Ongoing improvements in this tech...
