Résumé
The emergence of digital capture devices have enabled the developmentof 3D acquisition to scan the properties of a real object : its shape and itsappearance. This process provides a dense and accurate representation of realobjects and allows to avoid the costly process of physical simulation to modelan object. Thus, the issues have evolved and are no longer focus on modelingthe characteristics of a real object only but on the treatment of data fromacquisition to integrate a copy of reality in a process of image synthesis. In this thesis, we propose new representations for appearance functions from the acquisition with the aim of defining a set of multicale models of low complexity in size working in real time on the today's graphics hardware
