“…In addition, the skip spheres still cut the calculation time by a factor of 50%. The results show that a model consisting of 1190 polygons can be simulated for real-time auralization upto third-order at an interactive rate [35].…”

“…It can be noticed that with simple models and low order of reflections the precalculation can be done at interactive rates, which allows also moving sound sources and changing geometry. By interactive rates, an update rate of about 30 Hz of reflection parameters is meant [35]. However, the precalculation time rises rapidly when the order of reflections grows.…”

“…However, it involves solving the BTM line integral over the edge length exposed to the sound field. As a result, BTM-based methods has a higher computational cost and recent research has focused on noninteractive acceleration techniques [32] used in offline simulations [33], [44] and edge subdivision techniques for interactive simulation of relative simple scenes [49], [8], [7].

Extending the frontier of visual computing, sound rendering utilizes auditory display to communicate information to a user and offers an alternative means of visualization. By harnessing the sense of hearing, sound rendering can further enhance a user's experience in a multimodal virtual world. In addition to immersive environments, auditory displays can provide a natural and intuitive human-computer interface for many desktop applications. In this paper, we give a brief overview of recent work at UNC Chapel Hill on fast algorithms for sound synthesis and sound propagation. These include physically-based sound synthesis for rigid bodies and liquid sound generation, as well as numeric and geometric algorithms for sound propagation. We highlight their performance on different benchmarks and briefly discuss some problems for future research._____________________________ 978-1-4244-3701-6/09/$25.00 ©2009 IEEE

“…This makes it possible to compute sound taking into account the geometric relationship between the receiver and the sound source [Takala and Hahn 1992;Funkhouser et al 1998;Funkhouser et al 1999;Tsingos et al 2001;Lokki et al 2002]. These methods, however, do not treat the synthesis of sound waves radiated from sound sources.…”

In computer graphics, most research focuses on creating images. However, there has been much recent work on the automatic generation of sound linked to objects in motion and the relative positions of receivers and sound sources. This paper proposes a new method for creating one type of sound called aerodynamic sound. Examples of aerodynamic sound include sound generated by swinging swords or by wind blowing. A major source of aerodynamic sound is vortices generated in fluids such as air. First, we propose a method for creating sound textures for aerodynamic sound by making use of computational fluid dynamics. Next, we propose a method using the sound textures for real-time rendering of aerodynamic sound according to the motion of objects or wind velocity.
