본 논문에서는 비눗방울에 나타나는 반사와 굴절 효과를 상용 게임엔진인 유니티 쉐이더(Unity shader)를 사용하여 구현하고 다양한 배경에서 합성할 수 있는 효율적인 프레임워크를 제안한다. 본 논문에서 제안하는 방법은 계산량이 큰 유체 시뮬레이션을 이용하지 않고, 스넬(Snell)의 법칙을 이용하여 박막 내부의 굴절 벡터를 계산하고, 막 표면의 표현을 위해 다양한 텍스처(Texture)를 적용하였으며, vertex의 조정을 통해 비눗방울 자체의 움직임을 나타낼 수 있다. 결과적으로 실시간으로 높은 품질의 비눗방울을 표현할 수 있기 때문에 게임뿐만 아니라 가상현실 및 다양한 실시간 애플리케이션에 활용될 수 있다.

Lately the VR (Virtual Reality) game genre is becoming increasingly more popular and it has been cementing its place in the market as its own independent game genre. The key advantage of VR is that it lowers the barrier between player and the virtual world, thus creating an immersive experience. The suggested method develops a game that allows the player to experience what it is like to be visually impaired using the unique characteristics of VR. A distinctive feature of this game is that the character is provided only a limited range of sight, which is created using silhouette outlines. This restrictive visual field is then grafted onto VR and the player can indirectly experience blindness in a highly immersive manner. The silhouette outline along with the particle system is created using Oculus Rift, a headset highly used in VR game development, and Unity 3D game engine. We will also explain in detail regarding the removal of borders between the objects.
