Three-dimensional structures such as longitudinal vortex appear in the two-dimensional vortex street wake of a cylinder. These structures are very complex structures. It is important to understand the details of the three-dimensional structures in the two-dimensional vortex street wake. The purpose of this study is to construct the three-dimensional structures from layered cross-sectional images and to understand its structures. In the flow visualization, four cylinders with different diameter were used to change the Reynolds number. The 3D structure constructed in this study could be observed from any angles and the details of its structures were revealed.
