Two of the recent areas of research in Computer Graphics are street-lighting simulation and cooperative work. In the first, the user can generate images that give information about the perceptibility of streets at night. The second deals with specific difficulties posed when a certain problem is tackled bz several users simultaneously. Two work in the first area the users need to have proficiency at different levels, namely at the designer level, at the technical and at the legal level. As it is difficult for any user to be expert in all of these, problems can arise. We propose computer supported cooperation of multi-disciplinary users as a way to solve some of these problems. In this paper we describe an extension to LISA (Street-Lighting Simulation System) to support cooperation of multi-disciplinary users. The extension is made in three directions. The first is to add a cooperative user interface to enable a group of users to build scene descriptions cooperatively. The second is to enable different users to visualize separately the rendered results of the simulation. Finally the third direction, very important to enhance the group effectiveness, is to support communication among users.
