Abstract

Visual rendering is the process of creating synthetic images of digital models. The modelling of sound synthesis and propagation in a virtual space is called sound rendering. In this article we review different audiovisual rendering techniques suitable for realtime rendering of three-dimensional virtual worlds. Virtual environments are useful in various application areas, for example in architectural visualisation. With audiovisual rendering, lighting and acoustics of a modelled concert hall can be experienced early in the design stage of the building. In this article we demonstrate an interactive audiovisual rendering system where an animated virtual orchestra plays in a modelled concert hall. Virtual musicians are conducted by a real conductor who wears a wired data dress suit and a baton. The conductor and the audience hear the music rendered according to the acoustics of the virtual concert hall, creating a lifelike experience.
