Statement

I am a graduate student in the Department of Architecture at the University of Tokyo. My recent work began with a an art-science collaboration class taught by Tomohiro Tachi and Asao Tokolo. In this project, I explore curved surfaces generated by identical modules. My current interest focuses on how annular strips can construct variations of surfaces with constant negative curvature. Through the construction of geometric models, I investigate ways to visualize these mathematical phenomena. By allowing viewers to touch and transform the structure, the work invites an intuitive exploration of the parameters underlying the form.

This work allows viewers to explore continuous variations of saddle-shaped surfaces that emerge when the inner and outer edges of annular strips are joined. In a joint study with Prof. Tomohiro Tachi and Kanata Warisaya, we showed that the resulting surfaces of constant negative curvature can vary from a Beltrami pseudosphere to a flattened hyperboloid-type surfaces of constant negative curvature depending on how the ends of the strips are joined. Modular units are constructed from 3D-printed TPU annuli that first form an approximate pseudosphere, then are cut along a geodesic and fitted with sliders at the cut edges. Viewers can observe how the geodesics, perpendicular to the annular arcs, form helices and how frilled surfaces emerge.
