초록

사운드는 가상현실 및 컴퓨터 애니메이션에서 사용자의 현실감 및 집중도를 높이기 위한 중요한 요소이다. 최근에 컴퓨터 그래픽스 분야에서도 연구자들이 사운드 관련 연구들에 관심을 가지고 여러 컴퓨터 그래픽스 학술지와 학회에 주목할만한 연구결과들이 발표되고 있다. 본 논문에서는 컴퓨터 그래픽스 분야에서소개된 논문들을 중심으로, 컴퓨터 그래픽스에서 관심을가지는사운드연구의주제에대하여알아보고중요성을가지는논문들을소개한다. 특히본논문에서는다음두가지 분야의 논문들을 소개한다. 첫째, 사운드를 물리적으로 합성함으로써 그래픽스의 물리 법칙에 동기화되는 사운드를 생성하는것이다. 둘째, 음원에서나오는사운드가사람에게들리는음향적환경을모델링하는것이다. 사운드에대한연구에서주된관심은이러한음향학적인물리법칙을더욱효율적으로모델링하여적은자원으로도실제적인사운드효과를발생할수있는지에대한것이다. 이러한관점을중점으로다양한사운드관련논문들을살펴보고컴퓨터그래픽스와의관계를 살펴보도록한다.

Abstract

Sound is very important element to enhance and reinforce reality and immersion of users in virtual reality and computer animation. Recently, significant researches about sound modeling are presented in computer graphics cummunity. In this article, main subjects are explained and major researches are rewiewed based on the sound papers presented in computer graphics community. Specially, several papers about following two subjects are reviewed in this paper: 1) synthesing sound using physically-based laws and generating sound synchronized with graphics. 2) spatializing sound and modeling sonic environment. Many research about sound modeling have been focused on more efficient modeling of real physical law and generate realitic sound with limited resources. Based on this concept, various papers are introduced and the relationship between researches about sound and graphics is discussed.
