不可能方塊

不可能方塊
一個實際存在的物體,方塊的兩個邊上有缺口,若在特定角度下觀看時,就像是不可能方塊

不可能方塊是由M. C.埃舍爾版畫望楼英语Belvedere (M. C. Escher)》中創作的不可能物體[1][2]

不可能方塊是將奈克方塊中呈現的模稜兩可詮釋具體的表現出來。而且不可能方塊的各邊是實心的,不像奈克方塊只用一條線表示,因此在視覺上的衝突較大。不可能方塊是二維的圖像,但在人類的眼睛會試圖將它詮釋為一個三維物體的投影。若是一般各邊為實心,且各邊沒有缺口的方塊,不論以哪一個角度來看,都不可能出現不可能方塊的投影。但若將各邊為實心的方塊,利用強迫透視的原理在適當位置製造缺口,在適當角度下觀看,會出現不可能方塊的投影[3]

除了埃舍爾外,像喬斯梅伊英语Jos De Mey等藝術家,也有有關不可能方塊的藝術品[4]。 在1966年的《科学美国人》中有一張修改後的照片,名為「Freemish箱子」,內容就是不可能方塊[3][5],有一份奧地利邮票也是以不可能方塊為主題[6]
