In exploring computational representations as structural artifacts, we began our iteration process with a section cutting from a cone. In the beginning, we have some seemingly fundamental difference in transformations. One idea goes to a structurally driven form, and generating shapes in parametric way. The other evolves through a surface transformation. To merge these two ideas, the final form starts from two section curves from a cone. By slightly rotate the upper curve, we got an ellipse. The upper curve was then moved up unevenly in each point and finally for two basic shape curve for parametric design. By using computational design software, we got multiple subdivision of curve, and sort out multiple lists of point. By connecting those lists of points in a mathematics order, the structure is generated. With the increasing of subdivide points, a shape between the two base curves also formed. The poly lines create a hollow structure, which also create possibility in weight loading aspect. Further iterating the shape of base curve, a shape that is more fitting to human body would be generated. The parametric calculation also provide some randomness in the final structure, giving the physical structure a future possibility of explore its new usage. We decided to put the structure into a public indoor space to give it a longer life span and with more human interactions. Further exploration could be made on how people access this shape of bench and how people’s behavior changed by the orientation of seats and shapes of structure.
