Abstract
Abstract A modelling and control system for creating lighting designs off-line and for controlling on-line the operation of the actual lighting systems producing those designs. Using a programmable computer, the modelling system prompts inputs by the designer/programmer describing model objects and their parameters including stage dimensions, set pieces and their locations, performers and their positions, trusses, lamps and their parameters such as color, focus, intensity, beam edge, and the relations among the objects. The sytem computes the resutant lighting scenes, organized as cues and arranged and formatted to be compatible with actual lighting controller usage. The system displays the model environment in such a way as to facilitate the modelling operation and its results. It also also generates a variety of spreadsheets for use by the designer.
