Sažetak
The methods for the simulation of propagation of sound based on the principles of geometric acoustics have so far been used in homogenous environments. These methods are based primarily on the reflection, and calculate propagation only in homogenous media. The author in this paper presents alternative method based on the beamtracing method that can be used to calculate propagation of sound in non-homogenous environments. This method calculates not only reflection, but also the refraction of the sound waves. Also, the scene is not composed from the media and reflective boundaries. This method rather treats all objects in scene equally. All objects are treated as media in which sound propagates, and the discontinuums between objects cause reflection and refraction of sound. This method although more complex than its predecessors is able to calculate propagation of the sound more accurately, and can consider wider range of environments.
