提出了一种平面连杆机构的交互式编辑方法。给定工作链接作为输入，用户可以对所选部件的形状或运动进行有针对性的编辑，同时保留其他，例如，重要的功能方面。为了使这个过程直观和高效，我们提供了许多不同抽象级别的编辑工具。例如，用户可以通过移动关节直接改变连杆的结构，编辑连杆上选定点的运动，或对其外壳的大小施加限制。我们的方法在这些编辑过程中防止简并配置，从而确保机制始终正确运行。链接编辑对性能提出了标准方法无法提供的严格要求。为了实现交互式和强大的编辑，我们建立在一个符号运动学的方法，使用封闭形式的表达式，而不是数值方法来计算联动装置及其衍生物的运动。我们展示了我们的系统上的一组不同的例子，说明了潜在的适应和个性化的结构和现有的联系的议案。为了验证我们编辑的设计的可行性，我们制造了两个物理原型。
We present a method for interactive editing of planar linkages. Given a working linkage as input, the user can make targeted edits to the shape or motion of selected parts while preserving other, e.g., functionally-important aspects. In order to make this process intuitive and efficient, we provide a number of editing tools at different levels of abstraction. For instance, the user can directly change the structure of a linkage by displacing joints, edit the motion of selected points on the linkage, or impose limits on the size of its enclosure. Our method safeguards against degenerate configurations during these edits, thus ensuring the correct functioning of the mechanism at all times. Linkage editing poses strict requirements on performance that standard approaches fail to provide. In order to enable interactive and robust editing, we build on a symbolic kinematics approach that uses closed-form expressions instead of numerical methods to compute the motion of a linkage and its derivatives. We demonstrate our system on a diverse set of examples, illustrating the potential to adapt and personalize the structure and motion of existing linkages. To validate the feasibility of our edited designs, we fabricated two physical prototypes.
