Overview

Geometric propagation Very fast Can be used realtime Several propagation methods Reflection Diffraction Transmission

SLIDE 3

Propagation

Reflection Primary propagation method Causes echos

SLIDE 4

Propagation

Diffraction Sound bends around corners

SLIDE 5

Propagation

Transmission Sound travels through materials Hear sounds through walls

SLIDE 6

Implementation

Goals Base on frustum tracing system Add Transmission Add transmission properties Attenuation Refractive properties Support object interiors

SLIDE 7

Implementation

Accomplished Transmission Refraction Pass through Single transmission property Only supports thin walls

SLIDE 8

Future work

Support for interiors Multiple methods

f transmission

Multi-material objects Similar to multitexturing

SLIDE 9

Demo

SLIDE 10

Summary

Adds dimension to simulation Important for realism Allows much greater awareness Slower, but still realtime
