A room acoustics design tool for MPEG-4 conforming scene design

The following paper discusses issues regarding scene composition for 3D interactive audiovisual application systems. These systems generally provide auditory feedback to die user, so that a virtual room can be experienced both visually and acoustically. Until now, the design process of the room acoustic properties has always been separated from the process of visual modelling of the room, mainly because the tools that scene designers normally use do not provide the necessary features for an acoustic description. The work presented here is a successful approach to solve this problem. It simplifies the modelling task while considerably shortening the time necessary to design such scenes.
