Title: Adding semantic information to geometric models


Biography: Juan Carlos Torres


Both 3D software and hardware have matured. Nowadays it is possible to create precise 3D models of complex objects, edit them and print real objects from these 3D models.  But for many applications this is not enough. For instance, to manage 3D models of Cultural heritage artefacts we need also to associate non-geometric information linked to the model. For industrial applications this has been addressed using Building information modeling (BIM), that have evolved from Computer Aided Design.

Nevertheless BIM are not a good approach to link data to 3D meshes, as those created using laser scanner of structure from motion. Special methods have been proposed to associate data to the surface of 3D meshes. One successful approach is to apply the same techniques used by the Geographic Science community. The usefulness of GIS comes from the relation they implement between data and locations, which allows the user to perform spatial queries. In fact all the data is structured in a set of layers or maps, and every layer point has a known geographic coordinate. These ideas are also useful for any 3D model if we have data associated to its surface.
