A method of evaluating proposed external illumination systems for buildings of historical and architectural importance by computer-generating photo-realistic images is described. A three-dimensional CAD model is created from a series of photographs of the building. Positions of the light sources are then decided and material properties assigned to all surfaces. Commercial computer simulation software is used to simulate the lighting. An example is given in which software using an alternative global illumination algorithm was used to model the lighting of a large public building, the CAD model of which was generated from 100 photographs taken with a digital camera. Both qualitative and quantitative results were achieved. 7 refs.
