提出了一种可展开伸展壳体的交互式计算设计方法。我们实现了可展开的辅助学作为三角形连杆，可以通过简单的扩展机构来驱动，以呈现所需的自由形状的目标形状。这些结构的核心特征是目标形状在2D联动布局中被直接且唯一地编码。因此，该结构可以在平面上制造和组装，并自动部署到其3D目标配置中，而不需要任何SCAfi旧的、模板或其他临时支撑结构。我们将重点放在通过Inflation或重力加载的自动展开上，这在以前的工作中已经给出了严格的理论分析。本文在这些结果的基础上，提出了基于优化的直接操作工具来编辑和调整扩展链接结构，以便ff生态地探索设计方案。此外，我们的解决方案实现了基于模拟的Form-fiNding，其中使用展开机构作为Form-fiNding力交互地构建所需的目标表面。我们提供了几个设计案例研究，展示了我们方法的eff效率，并强调了在体系结构中的潜在应用。
We propose an interactive computational design method for deployable auxetic shells. We realize deployable auxetics as triangular linkages that can be actuated with simple expansive mechanisms to assume a desired freeform target shape. The core feature of these structures is that the target shape is directly and uniquely encoded in the 2D linkage layout. As a consequence, the structure can be fabricated and assembled in the plane and automatically deployed to its 3D target configuration without the need for any scaffold, formwork, or other temporary support structure. We focus on automatic deployment via inflation or gravitational loading for which a rigorous theoretical analysis has been given in prior work. Our paper builds upon these results and presents optimization-based direct manipulation tools to edit and adapt an auxetic linkage structure to effectively explore design alternatives. In addition, our solution enables simulation-based form-finding, where the desired target surface is interactively constructed using the deployment mechanism as a form-finding force. We present several design case studies that demonstrate the effectiveness of our approach and highlight potential applications in architecture.
