Abstract
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.
