In the emerging field of E-Commerce we show the great potential interest to create 3D virtual shopping centers. The study of a specific application: the creation of an electric household applicants warehouse enables us to highlight the possibilities of the VRML2.0 language to model, visualize and to do interactive walking inside the warehouse. Key features of VRML 2.0 are underlined and new extensions are proposed in order to achieve a better realistic and «human-like» behavior inside the virtual warehouse.
