초록

3D 컴퓨터그래픽에서 유체를 이용한 사실적인 시각효과(Visual Effects)는 영상의 질적 완성도를 높이는데 중요한 요소로 작용한다. 유체의 각 속성을 제어하여 물, 불, 폭발 등의 사실적인 움직임을 생성시키는 과정을 유체 시뮬레이션(Fluid Simulation)이라 한다. 일반적으로 유체 시뮬레이션의 제작은 주 시뮬레이션(Main simulation) 작업단계에 집중되지만, 이를 위한 사전준비 단계(Initial set up)인 초기 방출자에 대한 효과적인 생성방법이 중요하다. 이에 본 연구의 목적은 유체의 초기 방출 운동과 형태에 관여하는 요소들을 분석하고 이를 초기 제작공정에 적용할 수 있는 효과적인 방법을 제시하고자 한다. 이를 위한 연구의 전개는 첫째, 기존 관련 연구에 대해 분석 및 문제점을 제기하고, 둘째, 보다 효과적인 유체효과 시뮬레이션 진행을 위해, Dynamic Fluid Emitter Creation과 User Design Type Emission Velocity Solution에 대한 두가지 실험을 진행한다. 본 연구를 통해, 사용자 설계형의 방출 제어 솔루션을 통해 효율적인 초기단계의 유체 시뮬레이션 제작방법을 제시한다.

The realistic Visual Effects using fluid simulation in 3D computer graphics are operated as important factors to improve the quality of images. The process of creating realistic motions of water, fire, explosion by controlling each property of fluid is called fluid simulation. In general, the creation of a fluid simulation concentrates on the main simulation work phase, however an effective method for initial set up is important for the main simulation work. The purpose of this study is to analyze the factors involved in the initial emission motion and shape of fluid and propose methods that can efficiently apply this into the initial set up. For the process of the research, first, problems are raised based on related researches, and second, two experiments, 'Dynamic Fluid Emitter Creation' and 'User Design Type Emission Velocity Solution', are conducted for more effective fluid simulation. Through this research, the effective fluid simulation of initial set up phase will be suggested through the user design-type emission control solutions.
