This paper presents an application in the field of illumination and traffic engineering with the definition of its rendering pipeline. The system incorporates a new solution for the calculation of the energy that arrives at each polygon of the scenery from point light sources in the direct illumination step.
Also, we introduce an extension of the radiosity method to incorporate physical surface light sources with intensity distribution curves and a set of image transformation for the correct display of the results according with the behavior of the human visual system. The simulation methods are based on spectralsampling allowing photorealistic rendering of planned lighting hardware as well as safety checks of dark areas in the street.
