AI Technical Summary
Existing technologies suffer from low computational efficiency, high storage requirements, and inaccurate facet dimensions when generating mesh representations of hybrid rod and spherical lattices. This leads to easy breakage of the lattice structure at stress concentration points, affecting manufacturing accuracy and efficiency.
A computer-implemented method is used to generate an efficient mesh representation by identifying the intersections of constraint curves and rays on the mixed lattice surface. This method combines the traveling cube algorithm and Delaunay triangulation to process different curvature regions, ensuring that the facets accurately reflect the local curvature.
It improves the manufacturability and modeling efficiency of lattice structures, reduces the number of facets, improves stress concentration issues, and enhances the structural integrity and printing accuracy of parts.
