Study_2 on Zaha Hadid's Mobile Art Pavilion

From its central axis, the practice created a polar grid that divides the torus into 36 segments each of 10 degrees.
This pavilion is made up of hundreds of moulded fiber reinforced plastic (FRP) mounted on a skeletal steel frame. Each piece had to fit together like a giant jig-saw puzzle. Width of each panel dose not exceed 7.38 feet, packed in 51 shippable containers.

The minimum or smallest bounding or enclosing box for a point set in N dimensions is the box with the smallest measure (area, volume, or hypervolume in higher dimensions) which all the points lie within.

The pavilion’s primary shape, the practice used a torus — the geometric term for a doughnut — with the exhibition in the ring and the courtyard in the hole. Then started to distort the torus to create wider, lower spaces and thinner, higher spaces, sometimes double height, that vary the experience around the loop. Cutting through all materials, this ordering system is expressed on the surface as black lines running longitudinally over the pavilion, then underfoot across the entrance terrace. The pavilion’s latitudinal divisions aren’t simply horizontal cuts parallel to the ground plane, they are contours within the 3D model, known as isoparms.
