An outline projection of a rectangular solid object, rotating in depth, produces a moving rotating in depth illusory contour across the empty region where an edge would normally be located even though it is not physically present. Observers see a contour demarcating the junction of the two frontal surfaces of the object when it undergoes the figural transformation of rotation-in-depth. Two experiments, in which several types of temporal change were compared, demonstrated that translation, flicker, or no motion are ineffective in producing the contour compared to rotation-in-depth. Also the four lines constituting the two inducing vertices of the object were sufficient to produce the motion-induced contour during rotation-in-depth. Three demonstrations further clarifying the nature of the motion-induced contour are also reported.
一个在深度方向上旋转的长方体物体的轮廓投影，会在通常应该有一条边但实际不存在的空白区域产生一个在深度方向上移动旋转的虚幻轮廓。当物体进行深度旋转的图形变换时，观察者会看到一条轮廓线划分出物体两个正面的交界处。两项比较了几种时间变化类型的实验表明，与深度旋转相比，平移、闪烁或无运动在产生轮廓方面是无效的。而且构成物体两个诱导顶点的四条线足以在深度旋转过程中产生运动诱导轮廓。还报告了三个进一步阐明运动诱导轮廓性质的演示。
