Ambient Sound with Signed Distance Fields and Gradient Fields

Ambient sound is an important part of any video game. They can present the player with the world that is beyond what is on the screen and can have a key role in creating an immersive experience. In this paper we propose methods to map static ambient sounds on worlds of any size. The first method uses signed distance field and the second uses gradient fields. This research also contains methods to save this field into files and options that can be used to reduce the size of the files.
