Surface reconstruction is a technique for converting fine geometric models such as triangular meshes or unorganized points into a smaller number of curved surface patches. Here, the topology of surface patches should be taken into consideration, because the smoothness and continuity of the patches depend on their topology. This paper reports a method for forming the topology of surface patches for surface reconstruction methods, given an initial fine triangular mesh. It first clusters the triangular elements into several belt-like subregions along the mesh domain boundary, and then subdivides the subregions into rough elements. The rough elements can be used as surface patches by fitting them to the input triangular mesh. The topology of rough elements is suitable for surface reconstruction, because they are well-aligned along the domain boundary.
