据介绍:



这是浙江大学和UNC Chapel Hill,URJC Madria的合作成果,使用了一种连续方法替代传统的惩罚法。



这个工作是他们早期碰撞检测工作向碰撞响应方向的延伸,非常简单和优雅的想法。

Figure 1: Sticking and penetration problems: We highlight sticking and penetration problems in the Chain Benchmark (a)(14.3k triangles, 60fps) and the Rings Benchmark (b)(7.4k triangles, 35fps) with traditional penalty methods. Our novel continuous penalty force formulation can alleviate these problems based on continuous collision and force computation.
Abstract
We present a simple algorithm to compute continuous penalty forces to determine collision response between rigid and deformable models bounded by triangle meshes. Our algorithm provides a well-behaved solution in contrast to the traditional stability and robustness problems of penalty methods, induced by force discontinuities. We trace contact features along their deforming trajectories and accumulate penalty forces along the penetration time intervals between the overlapping feature pairs. Moreover, we present a closed-form expression to compute the continuous and smooth collision response. Our method has very small additional overhead compared to previous penalty methods, while significantly improves the stability and robustness. We highlight its benefits on several benchmarks.
