Abstract

The invention provides a curved surface grid generation method and device, equipment and a storage medium. The method comprises the following steps: constructing a triangular manifold grid on a curved surface; determining a corresponding subdivision node according to each grid edge of the triangular grid; the subdivision base point is located on the curved surface; connecting subdivision nodes corresponding to the grid edges forming the same triangle in the triangular grid, and obtaining subdivision grid edges; and constructing the curved surface grid by adopting the subdivided grid edges. According to the curved surface grid generation method and device, the electronic equipment, the storage medium and the computer program product, the characteristics of the extension direction of the curved surface do not need to be considered during use, the grid can be directly generated based on the nodes on the curved surface, and rich grid patterns can be generated.

Description

technical field [0001] The present disclosure relates to the technical field of computer graphics, and in particular to a method, device, device and storage medium for generating a curved mesh. Background technique [0002] With the development of computer-aided design technology, complex geometric surfaces have been widely used in architectural shape design and product shape design. In some application fields, due to the limitation of manufacturing process and cost, the complex geometric surface cannot be realized by the traditional method, but the space grid of the component is used, and the complex geometric surface is approximately expressed by the space grid. [0003] However, the spatial meshing of complex geometric surfaces needs to take into account the aesthetics of the mesh shape, the feasibility of the mesh, and the structural safety requirements; the existing methods for meshing complex combined surfaces are in some special applications. The aforementioned requi...
