The use of Virtual Environments for Training is strongly stimulated by important needs for training on sensitive equipments. Yet, developing such an application is often done without reusing existing components, which requires a huge amount of time. We present in this paper a full authoring platform to facilitate the development of both new virtual(More)
In this article, we present a parallel image processing system based on the concept of reactive agents. Our system lies in the oRis language, which allows to describe 5nely and simply the agents’ behaviors to detect image features. We also present a method of segmentation using a multi-agent system, and two biological applications made with oRis. The(More)
The aim of all education is to apply what we learn in different contexts and to recognise and extend this learning to new situations. Virtual learning environments can be used to build skills. Recent research in cognitive psychology and education has shown that acquisitions are linked to the initial context. This provides a challenge for virtual reality in(More)
A multiagent architecture is proposed in order to build a physics laboratory in virtual reality. Thermodynamics experiments are used for its validation. Classical numerical resolution of thermodynamics problems comes up against the number and variability of boundary conditions. Based on molecular dynamics, a multiagent approach is proposed, resting upon(More)
This paper introduces a Virtual Reality platform based on a dynamic multi-agent programming language. These tools have been designed to show that simulating a MultiAgent System in a virtual environment with dynamic properties can be used for Interactive Prototyping. This kind of prototyping has to be considered when the designed system cannot be described(More)
In this paper we propose a new metaphor of information retrieving, usable in foundation heritage management and publishing. Based on the net, the user is able to participate in virtual guided tours, sessions of conference-like. A human expert will be the guide for all the connected users. He will use different media (sound/video) to communicate; the members(More)
Brood sorting, observed in some ant colonies, is a major example of social insects ability to solve problems at the collective level. Two processes characterize this phenomenon : a process of aggregation of all brood items in a single cluster, coupled with a process of segregation of items in concentric annuli, each containing items of different type. The(More)
