1. ARTIS-GRAVIR / IMAG INRIA ERGA Lessons learned Isabelle Ratinaud Joëlle Thollot

2. ARTIS-GRAVIR / IMAG INRIA ERGA How to begin a collaboration ? A common research subject How to understand –Another scientific language –The goals of each speciality

3. ARTIS-GRAVIR / IMAG INRIA ERGA A computer graphist needs: –Terrain –Buildings, houses –Characters An archaeologist could have: –First step: excavation Topographical datas, numerical datas (x, y), objects –Second step: reconstruction Drawings (elevation, section), plans and maps An historian could have: –Human way of life, traditions, institutions … The datas ideally

4. ARTIS-GRAVIR / IMAG INRIA ERGA The datas in practice Lack of information –State of the remains after more or less 2000 years –Topographical datas in Greece Datas not immediately usable –More descriptions than drawings –Datas often unpublished and fragmented A computer graphist needs a visual and complete description of the scene

5. ARTIS-GRAVIR / IMAG INRIA ERGA 3D reconstruction Not only a research work for CG –Geometric modelisation: graphists –Demos, prototypes: engineers Validation of the results –Advices from the archaeologists –How to deal with the missing parts ? –How to deal with the hypotheses ? => Constant dialogue

6. ARTIS-GRAVIR / IMAG INRIA ERGA Rendering, Virtual Reality This is the job of the computer scientists  The easiest part of the project… Choice of the rendering style according to the archaeologists’ point of view

7. ARTIS-GRAVIR / IMAG INRIA ERGA What do we do now ? Pedagogical support: –Web site, CD ROM –Museum, archeological site Research in archaeology: –Validation of the hypotheses –Better understanding of the space  Need more work

8. ARTIS-GRAVIR / IMAG INRIA ERGA Happy few We have shared our knowledge Now Joelle knows what a doric column is and Isabelle what a billboard is ! For CG, a new scientific community : –Different points of view –New applications For archaeologists, another way to question their sources All of we want to continue this project !
