摘要：本文提出了一种基于维度的三角网格变形方法。通过指定尺寸类型、定义尺寸的区域和目标尺寸，网格会自动变形，以满足目标尺寸。网格变形基于使用重心坐标的基于空间的变形。变形手柄由一组三棱柱组成，通过网格分割、简化和简化网格的偏移自动创建。在变形中，将变形空间和固定空间分配给手柄中的每个棱柱，通过对控制顶点应用仿射变换并对变形空间应用基于空间的变形来使网格变形。机械零件的结果表明了我们方法的有效性。
AbstractIn this paper, we propose a triangular mesh deformation method based on dimensions. By specifying the type of dimensions, the regions defining the dimensions, and the target dimensions, the mesh is automatically deformed so that it satisfies the target dimensions. Mesh deformation is based on space-based deformation using barycentric coordinates. The deformation handle, which consists of a set of triangular prisms, is automatically created by mesh segmentation, simplification and offsetting of simplified mesh. In deformation, the deformation and fixed spaces are assigned to each prism in the handle, and the mesh is deformed by applying affine transformation to the control vertices and space-based deformation to the deformation space. Results for the mechanical parts show the effectiveness of our method.
