Une approche sémantique pour la réutilisation et l'adaptation de donnée 3D

Abstract : The number of applications and access devices 3D enabled increases steadily. This trend is encouraging the development of tools for the retrieval, the reuse and the adaptation of 3D data. Usually, such tools are developed in the narrow context of a specific application. This is partly because the 3D data are usually defined only by their geometry and by their appearance and are difficult to be considered in contexts independent from a specific application domain.
We consider these issues by proposing a solution that enhances 3D data description by semantic annotations and organizes them into a model (3DSEAM) according to the dimension described: geometry, appearance, topology, semantics and media profile. To accommodate the variability of the model in terms of semantic descriptions, we propose an extension of the OQL using 3DSEAM specific constructs. A platform (3DAF) federates the instantiation and the interrogation of such descriptions. Above 3DAF, we build a platform focusing on the reuse of 3D data and their semantics (3DSDL). In addition, we are adopting an approach of adapting 3D data based on semantic rules interpreted and executed by an adaptation platform (Adapt3D). The reuse and the adaptation processes employ an XML standard for 3D data: X3D. The transformations applied to data are implemented using XSLT.
An application that concerns the management of 3D urban scenes is proposed in order to validate the various formalisms introduced by our approach. The application is based on the instantiation of the description model using MPEG-7. The query process is supported by XQuery.
