The authors describe the data structure necessary to provide real time simulation and visualization of complex environments and situations. For the past three years (1993-96) the LISITT in Spain, has been working on the SIRCA research project to study the development of small and medium size car driving oriented simulators, using VR and evaluating it in comparison with conventional technologies. SIRCA is currently running on Silicon Graphics platforms with different performance levels. The graphical output can be presented in a high definition computer or video monitor or in head mounted displays. The driver's interaction is produced through a sensorized cockpit. Users are able to steer, speed up, and brake while they wear the HMD or look at a monitor screen. A three degrees of freedom mobile platform is being installed to feed back acceleration sensations. The overall structure of the simulator has been described in other publications (S. Bayarri et al., 1994). We focus on some of the algorithms and data structures required to provide real time simulation of the complex urban environment and its visualization under the conditions of VR devices.
