Abstract: A method and a device for simulating the realization of lighting effects in an environment are disclosed. The method may receive environment data, user input indicative of lighting effects, and data indicative of what installable devices exist. Based thereon, the method may generate at least one implementation option for each lighting effect and select one implementation option for each lighting effect. As a result, realization data based on the environment data and selected implementation options options can be generated. A simulator for simulating realization of lighting effects is adapted to communicate, on the one hand, with a user or other provider of environment and lighting effect data, and, on the other, with a source of information on installable hardware device. The simulator can be operable in a design mode, an implementation mode, a selection mode and a realization mode.
