Abstract: A collision resolution modeling method between a particle and an object in a particle system is provided to flexibly control forces acting on a collision resolution method according to attributes of the particle system. With regard to a particle and a boundary particle, a bounce force acting in inverse proportion to a distance between the two objects is calculated. A repulsive force for modeling a non-bounce collision is calculated by changing a normal component of a force and speed acting on the particle. A damping force for the boundary particle and the particle is calculated. The calculated bounce force, repulsive force, and damping force are controlled to calculate overall forces for a particle system(100).

Abstract: 본 발명은 시간 연속적 텍스쳐 합성 기술에 관한 것으로, 삼각 메쉬(triangular mesh) 형태로 구성된 3차원 표면 위에 2차원 텍스쳐 이미지를 합성하는 기법으로, 특히 물과 같이 시간에 따라 형태나 위상이 급격하게 변화하는 표면에서도 텍스쳐가 부드럽게 변화하는 텍스쳐 합성 기법으로서, 특정 프레임의 텍스쳐를 합성할 때 이전 프레임의 텍스쳐 합성 결과를 참고함으로써, 프레임 간의 연속성을 최대한 보존한다. 따라서 시간에 따라 3차원 표면의 형태가 일그러지거나, 구멍이 뚫리거나 또는 원래 존재했던 구멍이 없어지는 등의 위상 변화가 잦은 애니메이션에서도 효과적으로 사용되는 것을 특징으로 한다. 본 발명에 의하면, 물과 같이 시간에 따라 형태나 위상이 급격하게 변화하는 3차원 표면에서 텍스쳐가 시간적으로 부드럽게 변화하는 텍스쳐 합성을 가능하게 할 수 있으며, 텍스쳐 합성 시 삼각형을 합성 단위로 함으로써 픽셀 기반 기법보다 효율적이고, 다중 스레딩을 도입함으로써, 합성 속도를 더욱 빠르게 수행할 수 있다.
