Abstract. We present a client/server system that is able to display 3D scenes on handheld devices. At the server we extract the geometry that is visible for each client and send it. We also extract texture and material information. The clients, running on mobile devices, use that information to render realistic images. Our geometry extraction algorithm employs multiresolution and view-dependent simplification. We present results of our system running on PocketPC 2003 PDAs.

The popularity of 3d graphics has grown exponentially in the latest years, which has lead to an increase in the range of applications where this kind of representations are used. The monitoring of industrial processes is an area where this type of simulation is rarely used, being much more common to show the information in traditional 2d interfaces.An application for data visualization in maritime container terminals is introduced here. We have developed a modular system adaptable to any stacked objects problem. This paper describes the architecture of our system, its features, and the graphics techniques applied to achieve a high frame rate and keep it independent of the data size.
