In this paper, we propose a novel image indexing platform, so-called INVENIO (INdexing Visual ENvironment for multimedia Items and Objects). INVENIO offers to professional users both 2D and 3D content re-use facilities. Concerning the 2D aspects, the system is entirely based on the ISO/MPEG-7 normative specification. INVENIO integrates visual metadata extraction engine, annotation tools, image databases management tools, as well as appropriated, ergonomic user interfaces. In the case of 3D graphical content, INVENIO makes it possible to exploit existing animation curves for generating new content and thus accelerating the content production process
