The underground deposit of the Orgnac aven is an accumulation that could host a wildlife trapped in the Quaternary. It has a pure morphology, unconstrained by wall effects. For two years, this deposit is the subject of archaeological and paleontological excavations and is studied by lasergrammetry. This preliminary work shows the integration of spatial data for the research in the 3D model and presents some perspectives : sedimentary surface fitting, taphonomic analysis, 3D reconstruction and virtual reality.Le cône d'éboulis de l'aven d'Orgnac constitue un dépôt endokarstique qui a pu accueillir une faune piégée au cours du Quaternaire. Il présente une morphologie pure, non contrainte par des effets de paroi. Depuis deux ans, ce cône fait ...
