保持离散微分特性的交互式网格编辑技术有望支持汽车钣金件等机械零件的设计。然而，现有的方法缺乏操作的能力，形状特征和硬约束，这是常见的工程应用。在产品设计中，三维模型上的某些区域经常需要在变形过程中精确地保持表面类型和参数。在本文中，我们提出了一个离散的框架保持形状的形状特征，使用硬约束的交互式形状变形。计算变形的形状，以便形状特征平移和旋转，同时根据操纵手柄保持其原始形状。此外，我们展示了如何使用线性约束来约束形状特征的运动。所实现的系统可以实现约束变形的实时响应。
Interactive mesh editing techniques that preserve discrete differential properties are promising to support the design of mechanical parts such as automobile sheet metal panels. However, existing methods lack the ability to manipulate form-features and hard constraints, which are common in engineering applications. In product design, some regions on a 3D model are often required to precisely preserve the surface types and parameters during deformation. In this paper, we propose a discrete framework for preserving the shapes of form-features using hard constraints in interactive shape deformation. Deformed shapes are calculated so that form-features translate and rotate while preserving their original shapes according to manipulating handles. In addition, we show how to constrain the motion of form features using linear constraints. The implemented system can achieve a real-time response for constrained deformation.
