Abstract
International audience; The need for the real-time interactive co-visualization of 3D urban environments on a Web-based virtual Globe arises naturally in GIS but it still remains challenging due to the complexity of city models and their huge data sizes which largely overload the computational power and memory capacity of client devices. Especially on the Web, the visualization of city models makes their rendering not real-time because of the lack of content adaptation and progressive data transmission. This paper presents technical solutions for the co-visualization of massive city models in a Web-based virtual globe, allowing navigation over 3D cities on the g...
