Virtualization, Virtual Environments and Content-based Retrieval of Three-Dimensional Information for Cultural Applications

摘要

The present paper proposes a virtual environment for visualizing virtualized cultural and historical sites. The proposed environment is based on a distributed asynchronous architecture and supports stereo vision and tiled wall display. The system is mobile and can run from two laptops. This virtual environment addresses the problems of intellectual property protection and multimedia information retrieval through encryptation and content-based management respectively. Experimental results with a fully textured 3D model of the Crypt of Santa Cristina in Italy are presented, evaluating the performances of the proposed virtual environment.
