Calculating 3D Sound-Field using 3D Image Synthesis and Image Processing

This paper proposes several algorithms to compute the 3D sound-field in complex environments. The basic idea is to explore the similarities of light and sound propagation and take advantage of efficient rendering algorithms and hardware to compute the sound field. First we consider only the direct effect of sound sources. Then single reflections of the sound are also computed using the analogy of local illumination models. The main problem in establishing such an analogy is that the effects of different sources emitting different sound waves cannot be added. Instead we have to keep the information from which source this sound was emitted.
