Abstract: 물의 용존산소량을 고려한 얼음 생성 시뮬레이션 장치 및 방법이 개시된다. 좌표공간 분할부는 복수의 입자로 이루어진 액체가 사전에 설정된 3차원 좌표공간에서 고체로 변화하는 과정을 시뮬레이션하기 위해, 3차원 좌표공간을 동일한 크기의 복수의 격자로 분할한다. 입자상태 결정부는 각각의 격자 내부에 위치하는 입자 각각의 상태를 격자의 노드로부터 전달받은 열량에 따라 결정한다. 용존산소량 분배부는 결정된 입자의 상태가 고체인 얼음 입자와 결정된 입자의 상태가 액체인 물 입자 사이의 거리를 기초로, 얼음 입자가 가진 용존산소량을 물 입자로 분배한다. 렌더링부는 복수의 입자 각각이 가지는 열량 및 용존산소량을 기초로 각각의 입자의 최종 상태를 결정하여 렌더링한다. 본 발명에 따르면, 얼음이 생성되는 과정에서 내부의 공기 방울을 생성하여 사실적이고 세밀하게 얼음을 표현할 수 있다. 이때 용존산소량 필드를 생성하여 낮은 격자 해상도에서도 더 나은 결과를 산출할 수 있다. 그리고 거리장 기법을 이용하여 다양한 형태의 얼음을 생성할 수 있다. 또한 액체와 고체처럼 열 전도율이 다른 물질의 열 전도 시뮬레이션을 수행할 수 있다.

Abstract: PURPOSE: An ice formation simulation device considering the dissolved oxygen of water and a method thereof are provided to express ice realistically and minutely by generating air bubbles inside ice in an ice generating process. CONSTITUTION: A coordinate space partitioning part (110) divides a 3D coordinate space into the lattices of the same size for simulating the process of liquid, which is formed with particles, transforming into solid in the 3d coordinate space. A particle status determining part (120) determines the status of the particles inside the lattice according to the amount of heat delivered from the node of the lattice. A dissolved oxygen distributing part (130) distributes the amount of dissolved oxygen of an ice particle to a water particle based on the distance between the water particle and the ice particle. A rendering part (140) determines the final state of the particles based on the amount of heat of particles and the amount of dissolved oxygen of particles for rendering.
