Computational Design of Actuated Deformable Characters

We present a method for fabrication-oriented design of actuated deformable characters that allows a user to automatically create physical replicas of digitally designed characters using rapid manufacturing technologies. Given a deformable character and a set of target poses as input, our method computes a small set of actuators along with their locations on the surface and optimizes the internal material distribution such that the resulting character exhibits the desired deformation behavior. We approach this problem with a dedicated algorithm that combines finite-element analysis, sparse regularization, and constrained optimization. We validate our pipeline on a set of two-and three-dimensional example characters and present results in simulation and physically-fabricated prototypes.

我们提出了一种面向制造的驱动可变形角色设计方法，该方法允许用户使用快速制造技术自动创建数字设计角色的物理复制品。给定一个可变形角色和一组目标姿态作为输入，我们的方法会计算出一组数量较少的驱动器及其在表面上的位置，并优化内部材料分布，使得最终的角色呈现出期望的变形行为。我们通过一种专用算法来解决这个问题，该算法结合了有限元分析、稀疏正则化和约束优化。我们在一组二维和三维示例角色上验证了我们的流程，并展示了模拟结果以及实际制造的原型。
