Hierarchical radiosity is a very demanding process in terms of computation time and memory ressources even for scenes of moderate complexity. To handle complex environments, not tting in memory, new solutions have to be devised. One solution is to partition the scene into subsets of polygons (3D cells or clusters) and to maintain in memory only some of(More)
In this paper we propose a new metaphor of information retrieving, usable in heritage management and publishing. Based on the net, the user is able to participate in virtual guided tours, sessions of conferences-like. A human expert will be the guide for all the connected users. He will use different media (sound/video) to communicate; the members of the(More)
—Museums like marine aquariums are facing a difficult problem when trying to deliver information to their visitors. The exhibits they propose are dynamic by definition. Each may contain multiple autonomous entities that need to be described to the visitor. Classical communication means (panels, audio-guides ...) are static and do not adapt to the(More)
This paper introduces a new device model and a new interaction technique model to deal with plasticity issues for Virtual Reality (VR) and Augmented Reality (AR). We aim to provide developers with solutions to use and create interaction techniques that will fit to the needed tasks of a 3D application and to the input and output devices available. The device(More)
Museum are always looking for new attractions and ways of communicating with visitors. Here we describe an virtual guide as a new information support for visitors of an aquarium, using augmented reality technics. The guide is able to autonomously adapt to the particular constraints of this dynamic environment through the execution of a(More)
