Bruno Arnaldi – författare

Virtual and Augmented Reality have existed for a long time but were stuck to the research world or to some large manufacturing companies. With the appearance of low-cost devices, it is expected a number of new applications, including for the general audience. This book aims at making a statement about those novelties as well as distinguishing them from the complexes challenges they raise by proposing real use cases, replacing those recent evolutions through the VR/AR dynamic and by providing some perspective for the years to come.

The 9th Eurographics workshop on Animation and Simulation was held on Au- gust 31st -September 1st, 1998, at INESC Lisbon. The workshop was chaired by Bruno Arnaldi (IRISA Rennes, France) and Gerard Hegron (Ecole des Mines de Nantes, France). The local organizer Mario Rui Gomes (INESC Lisbon, Por- tugal) notably contributed to provide a harmonious environment. The main theme of this seventh workshop was centered on Virtual Reality versus Anima- tion and Simulation: from real time animation/simulation to physical perception of virtual environments. About twenty participants attended the workshop, rep- resenting eight countries: France, Spain, Austria, Switzerland, Ireland, Portugal, Germany and USA. The Program Committee selected eight papers among sub- mitted papers. Thirteen minutes of presentation and fifteen minutes discussion time per paper was also planned; this approach succeeded in creating a stimu- lating exchange atmosphere during the two days.Four sessions have been organized : Applications : in this session, two papers were presented, the first one deals with the use of simulation in natural desasters prevention while the second one concerns dynamic light sources for radiosity environments natural simulation : the first paper of this session presents works on real time behavioral simulation from psychological studies, the second one deals with identification of motion for living beeing. Interaction : the first paper presents a method for interactively animate solid using displacement contraints and the second paper presents the modeling of objects for interactive virtual human tasks.
