With specially arranged inducing elements on a white surface of uniform luminosity, a phenomenally complete Necker cube can be seen in any array where only the 'corners' of the cube are physically represented. The subjectively seen bars of the cube disappear when the inducing 'discs' are seen as 'holes' in an interposing surface, through which the corners of a partially occluded cube are viewed. Illusory brightness effects are also observed in connection with the different organizations of this ambiguous figure.
在均匀亮度的白色表面上设置特殊的诱导元素，在任何仅物理呈现立方体“角点”的阵列中，都能看到一个极其完整的内克尔立方体。当诱导“圆盘”被视为插入表面中的“孔洞”时，主观上看到的立方体线条就会消失，透过这些孔洞可以看到一个部分被遮挡的立方体的角点。与这个模糊图形的不同组织形式相关联，还观察到了虚幻的亮度效应。
