Tools for simulation and visualization of complex illumination environments

The aim of this paper is to present the tools and methods developed for the visualization and simulation of industrial complex illumination projects, such as the ergonomics and usability of space inside buildings or the analysis of vial security scenarios. In such cases, not only realistic illumination but also moving objects or persons are key for human perception. The developed tools consist of two software packages for calculating lighting simulation, a package for the simulation of the human visual system and another package for the animation of human locomotion. All these software are integrated in our Cave-Like System. The simulations done with our hardware and software include the physical phenomena that happen when light and matter interact in complex environments where there are moving elements, amongst which virtual humans stand out. In this way, the results presented in the immersive environment are as close to reality as possible, as perceived by a human observer.
