Abstract : In this report, we present a method allowing to visualize and interact with massive virtual urban environments adapted to mobile and connected devices like PDA or mobile phones. These devices have a very limited computational power and a restricted display area. We address these constraints using two optimizations. The first one is locale, we propose a simplified representation of building' facades as an alternative for textured rendering. Feature lines are extracted from facade images and vectorised. The resulting representation is more compact than the original image and allows to optimize transmission and rendering costs. As a global optimization, we split up the urban scenery in cells using the Magellan framework. Then we compute visibility relationships between the cells in order to stream the model.
