본 논문에서는 GPU 기반으로 옷감을 찢는 데 필요한 동적 재메쉬 기법에 대해서 제안한다. 일반적으로 메쉬를 파괴(Fracture)하거나 찢는 시뮬레이션에서는 안정적인 동역학 계산하는데 있어서 동적 재 메쉬과정에 매우 중요하며 이 과정이 계산양이 가장 크다. 본 논문에서는 GPU 친화적인 동적 메쉬 알고리즘을 새롭게 제안함으로써 옷감 찢기 시뮬레이션을 실시간으로 보여준다.

In this paper, we propose a GPU-based method for real-time processing of dynamic re-meshing required for tearing cloth. Thin shell materials are used in various fields such as physics-based simulation/animation, games, and virtual reality. Tearing the fabric requires dynamically updating the geometry and connectivity, making the process complex and computationally intensive. This process needs to be fast, especially when dealing with interactive content. Most methods perform re-meshing through low-resolution simulations to maintain real-time, or rely on an already segmented pattern, which is not considered dynamic re-meshing, and the quality of the torn pattern is low. In this paper, we propose a new GPU-optimized dynamic re-meshing algorithm that enables real-time processing of high-resolution fabric tears. The method proposed in this paper can be used for virtual surgical simulation and physics-based modeling in games and virtual environments that require real-time, as it allows dynamic re-meshing rather than pre-split meshes.
