1st Key: Descritization
The whole structure can be considered as a repetition of modular units, which are classified as two types of continuous curved stripes from a construction point of view (one with strip openings and one without), with the same mathematic description.
2nd Key: Mathematics
Each of the single modular unit can be defined by an arch on the latitudinal direction, and a curve described by a periodic function on the longitudinal one. As a whole, the unit can be described by a mathematic equation composed of three variables.
3rd Key: Shape
Each modular unit can be seen as a result of lofting operation – that is, to take an arch as the section of the shape alongside a periodic curve (vice versa), so that the curved surface is generated.
