Openness Ratio: Density Variation on the Same Panel

A metal plate with varying perforation density. The plate surface is covered with circular holes, whose diameter and spacing continuously change from one end to the other: at one end, the holes are small and sparse, approaching a solid surface, while at the other end, the holes are large and dense, approaching a mesh. Thus, the same plate simultaneously functions for both concealment and transparency. Light passing through from behind forms a gradient of light spots. Avoid: using uniform perforations, making the change in hole diameter discontinuous or abrupt, making the holes too large and losing the sense of a plate, using irregularly arranged holes.

一片開孔密度變化的金屬板。板面上佈滿圓形的孔洞,孔的直徑與間距從一端到另一端連續變化:一端的孔小而稀疏接近實面,另一端孔大而密集接近網狀。因此同一片板同時具有遮蔽與穿透的功能。背後的光透過來時形成漸層的光點。避免:使用均勻一致的開孔、讓孔徑的變化跳躍不連續、把孔做得過大失去板的感覺、使用不規則排列的孔洞。
