我们介绍了一种方法,有效地计算精确的最短路径的边界的网格从一个给定的内部点存在的自相交。本文给出了自相交物体最短边界路径的形式化定义,并给出了一个计算实际最短边界路径的鲁棒算法,从而为在模拟可变形体物体时,利用不保证碰撞分辨率的快速模拟技术,解决碰撞和自碰撞问题提供了一种有效的解决方案。我们的评估包括复杂的自碰撞的情况下,大量的活动接触,表明我们的方法可以成功地处理它们,通过引入一个相对较小的计算开销。
We introduce a method for efficiently computing the exact shortest path to the boundary of a mesh from a given internal point in the presence of self-intersections. We provide a formal definition of shortest boundary paths for self-intersecting objects and present a robust algorithm for computing the actual shortest boundary path. The resulting method offers an effective solution for collision and self-collision handling while simulating deformable volumetric objects, using fast simulation techniques that provide no guarantees on collision resolution. Our evaluation includes complex self-collision scenarios with a large number of active contacts, showing that our method can successfully handle them by introducing a relatively minor computational overhead.
