  • Description of Work

    The ARCHEOS research initiative set out to meet a number of goals. The first, and probably the most important goal was to establish a working relationship between archeologists, historians and architects on the one side, and computer graphics/VR researchers on the other. The second goal was to investigate issues relating to rendering styles, and notably non-photorealistic rendering, and in particular in relationship with archeological applications. The context of this second goal was concentrated in immersive or semi-immersive virtual reality systems, such as the workbench at INRIA Sophia-Antipolis, or the RealityCenter in Grenoble.

    A number of meetings and working groups (see next section), have taken place in the context of the ARCHEOS research initiative, with participants from different domains, establishing a core multi-disciplinary group of researchers. The discussions concentrated on three main directions: (i) computer graphics (CG) research directions, with an emphasis on non-photorealism and its application to archeology and history, (ii) the importance of CG and Virtual Reality (VR) for archeology and (iii) the development of Virtual Experiences to help archeologists and historians in their work, for education and for presentations to the general public.

    In terms of the CG research, the main thrust of work was guided by Joelle Thollot at the ARTIS research group of the GRAVIR Laboratory in Grenoble, France. Details of this research are presented below; a number of publications have resulted, notably on the rendering of paper canvas for walkthroughs, the simulation of emergent crowds and water-color style renderings. Another direction included the implications of using stereo for canvas representation, which is work in progress at REVES/Inria Sophia-Antipolis.

    A number of talks and a poster were presented at archeological forums based on initial results of this work. The initial reaction of archeologists has been very positive, and we believe that this work will foster further cross-disciplinary actions. The archeological work has concentrated on the Argos project, which is the center of interest of the ERGA  group in Grenoble, who participate in the project.

    Finally, based on our multi-disciplinary discussions, at REVES/Inria Sophia-Antipolis, we are designing VR experiences for educational and archaeological research purposes.

    Meetings/Discussions

    To date, we have had seven meetings, all of which included participants from the various disciplines involved. Other than the July 2003 meeting which concentrated mainly on CG research, allother meetings discussed various aspects of the interaction between the disciplines involved. We wish to highlight the meeting of September 2002 in Grenoble (Monbonnot), in which major archeologists of the Argos site (M. Pierart and A. Pariente) discussed at length how these technologies can help their work after seeing interactive demos developed by ARCHEOS. For a detailed list of the meetings and the participants, please see the Meetings page.

    CG Research Directions

    Under the direction of Joelle Thollot, Matthieu Cunzi investigated the important issue of rendering canvas in the context of walkthroughs for computer graphics, in the context of a DEA (2002). This resulted in a publication at Graphics Interface 03 , with the collaboration of G. Debunne, S. Paris from ARTIS and F. Durand from MIT.

    A second research direction involved the inclusion of crowds in archeological non-photorealistic renderings. This work was pursued by Laure Heigeas, under the supervision of Joelle Thollot and Annie Luciani in Grenoble during the academic year 2001-2002, resulting in a publication at Graphicon 2003.

    Under the direction of Joelle Thollot, Pascal Barla investigated issues related to water color renderings in a DEA (MSc) at ARTIS in 2003. Initial results have been presented in his DEA report.

    At REVES INRIA Sophia-Antipolis, Roman Bayon did his engineering school thesis work under the direction of George Drettakis. The goal was to investigate the implications of stereo for various NPR algorithms, and notably the canvas algorithm presented previously. This work is currently in progress, and a first report exists in French.

    All of the above activities were funded in part by ARC ARCHEOS.

    Conferences and Presentations

    I. Ratinaud and M. Cunzi will be presenting ARCHEOS at a Symposium on Argos to take place in Athens at the Ecole Francaise d'Athenes, organized by Marcel Pierart.

    I. Ratinaud  presented work related to ARCHEOS at a seminar in Fribourg in September 2003.

    I. Ratinaud and J. Thollot presented their poster at the International Conference of Classical Archeology 2003.

    In the context of ARCHEOS, M. Cunzi and J. Thollot presented their paper at Graphics Interface'2003.

    F. Letoublon organised a conferencein Grenoble in november 2002, where the Argos project and some of the  results of ARCHEOS were presented.

    G. Drettakis attended EGVE 2002 and P. Martinez SIGGRAPH 2003, where he presented virtual archeology work.

    Some of these trips were partially funded by ARCHEOS.

    VR Experience Construction

    At REVES/INRIA Sophia-Antipolis we are in the process of building two VR experiences/demonstrators, based on our discussions with the archeologists involved in the project.

    The first demonstrator illustrates the two hypotheses for the Tholos monument in the ancient Argos Agora. The images below are snapshots from the simulator which we have developed for these demos.

    Pierart Hypothesis
    Marchetti Hypothesis
    The Pierart Hypothesis in the VR system
    The Marchetti hypothesis in the VR system
    Interactive Tholos 1
    Interactive 2
    The reconstructed Tholos is superimposed on the remains of today
    The user can manipulate the pieces interactively

    The second demonstrator will show Argos through different eras, geometric, classical and Roman (shown above).
