奥尔比祖错视长方形有看起来向内侧凹的特性。如果背景加上同心圆的话,这种特性将被进一步突出。长方形看起来似乎发生了变形,是吗?坡根多尔夫错视如果用长方形挡住斜线的话,那么斜线看起来好像发生了偏移。左图中,与a连接的好像是b,但实际上是C,是吗?
Olbizo misses the rectangle to look concave inwardly. This feature will be further highlighted if the background is concentric. The rectangle seems distorted, is it? Poggenhoff Errors If the slash is blocked by a rectangle, the slash looks as if it has been offset. In the diagram to the left, it looks like b is connected to a, but is actually C, is it?
