This object was produced by students during a digital fabrication course that I taught. Students studied the geometries of compound curved surfaces, and multiple methods of constructing them from flat sheet materials. As most construction materials cannot be stretched to form compound curved geometries, we need to create a series of flat patterns that can be assembled into a visual approximation. A surface that can be reduced to a flat pattern without being distorted is called developable. This student team chose to reduce the original curved surface into a triangulated mesh, as each face would automatically be a flat plane. The pieces are aggregated together with zip ties as a joinery system.
