Item Physical Cyclic Animations(ACM Association for Computing Machinery, 2023) Jia, Shiyang; Wang, Stephanie; Li, Tzu-Mao; Chern, Albert; Wang, Huamin; Ye, Yuting; Victor ZordanWe address the problem of synthesizing physical animations that can loop seamlessly. We formulate a variational approach by deriving a physical law in a periodic time domain. The trajectory of the animation is represented as a parametric closed curve, and the physical law corresponds to minimizing the bending energy of the curve. Compared to traditional keyframe animation approaches, our formulation is constraint-free, which allows us to apply a standard Gauss–Newton solver. We further propose a fast projection method to efficiently generate an initial guess close to the desired animation. Our method can handle a variety of physical cyclic animations, including clothes, soft bodies with collisions, and N-body systems.
