Augmented CGI Films

The contribution of this paper focuses on the definition of a multimedia application targeted at turning CGI films into a richer and more interactive experience. We combine highquality animated graphics to present a compelling story and enrich it by introducing a certain degree of interactivity: allowing the user to watch films using different camera paths. One of the main goals is to provide alternative ways to observe different facets of the same story, different versions according to user profiles and preferences. We propose a generic coding scheme for high-quality 3D animation, and augment it with an XML content descriptor. Based on the MPEG-7 standard, the descriptor provides information such as preset camera paths that can be freely chosen by the user.
