Fuller | Geodesic Dome: The Structure Itself is a Climbing Frame

A spherical grid composed of equal-length members: all triangles are arranged according to the same set of geometric rules, and the efficiency of the structure allows extremely thin members to support large spans. This grid also happens to be the most suitable shape for climbing—every node is a position where hands can grip and feet can step, and it works for climbing from any direction. The members are steel or aluminum tubes, connected at nodes with simple joints, and are either painted a single color or left unpainted. The sphere is partially embedded in the ground to form a dome. The ground is sand or grass. Photographed during the day, the geometry of the grid and its transparency are simultaneously visible. Avoid: members thickened into solid structures, external cladding added, irregular grid arrangement, additional platforms and slides.

一個由等長桿件構成的球面網格:所有的三角形以同一套幾何規則排列,結構的效率讓極細的桿件就能撐起大跨度,而這個網格恰好也是最適合攀爬的形狀——每一個節點都是手可以抓、腳可以踩的位置,而且從任何方向爬上去都行得通。桿件為鋼管或鋁管,節點以簡單的接頭連接,表面塗成單色或不塗裝。球體局部埋入地面形成穹頂。地面為砂或草。日間拍攝,網格的幾何與其穿透性同時可見。避免:桿件加粗成實體結構、加設外覆面材、網格排列不規則、加上額外的平台與滑梯。
