Efficient representation and model generation method of conformal lattice filling thin-wall structure

The invention provides an efficient representation and model generation method for a conformal lattice filling thin-wall structure, and belongs to the technical field of additive design. Geometric information of the lattice structure is efficiently represented by the matrix, the lattice structure is quickly modified by modifying the matrix, and computer memory overhead is low. On the basis of the efficient geometric information representation method, an outer-layer thin wall recognition and thin-wall structure geometric model generation method of the lattice structure is provided, the outer-layer thin wall can be automatically generated according to an algorithm process, good connectivity is achieved between the outer-layer thin wall and the lattice structure, and the accuracy of the outer-layer thin wall recognition and thin-wall structure geometric model generation method is improved. And manual design and adjustment of the outer-layer thin-wall structure are not needed. By means of the geometric model gene
