A high-quality block structure of a 3D model can support many important applications; however, the automated generation of a high-quality block structure is still a challenging problem. In this paper, a dual surface-based approach to automated and valid block decomposition of 3D models is proposed. First, dual loops for block decomposition are generated with the help of a computed frame field whose three types of degenerated singularities are corrected. Then, a required dual surfaces set is constructed to suitably separate all the boundary elements of the 3D model and singularities of the frame field with the help of the basis of the non-trivial loops on the boundary surfaces. Finally, a valid block structure is obtained by performing dual operations along the dual surfaces on the hex mesh generated by splitting the tetrahedral mesh of the 3D model. Experimental results showed the effectiveness of the proposed approach. |
