3D-mesh models are widely used to represent real objects in synthesized scenes for multimedia or cultural heritage applications, medical or military simulations, video games and so on. Indexing and analyzing these 3D data is a key issue to enable an effective usage of 3D-mesh model for designers and even for final users. The researches of our group mainly focus on these problems. In this paper, we present the work of our group for the DELOS NoE during the year 2006. We have worked on two approaches for 3D-model indexing and analyzing: view-based approach and structural approach. View-based approaches for 3D-model indexing are a very intuitive way to retrieve 3D-models among wide collections by using 2D natural views (as a human uses to represent 3D-objects). Structural analysis of a 3D-mesh model gives a structural decomposition of the object from a raw boundary representation of it, then this decomposition can be used to segment or index 3D-models.
