Rotation of a Kanizsa triangle in depth around its vertical axis causes a perception of a three-dimensional object with a flat, rigid illusory triangle between the inducing discs. When the inducing discs of a Kanizsa triangle were made thicker, the illusory triangle between the discs also became thicker. In the experiments both computer animation and real inducers made of plastic were used. The method promoted border perception in a three-dimensional illusory figure. We suggest that the perception of three-dimensional illusory objects is due to a process which is also used in the perception of real three-dimensional objects.
卡尼萨三角围绕其垂直轴进行深度旋转时，会让人感觉到一个三维物体，在诱导盘之间有一个扁平、刚性的虚幻三角形。当卡尼萨三角的诱导盘变厚时，盘之间的虚幻三角形也会变厚。在实验中，既使用了计算机动画，也使用了由塑料制成的真实诱导物。该方法促进了三维虚幻图形中的边界感知。我们认为，对三维虚幻物体的感知是由于一个在对真实三维物体的感知中也会用到的过程。
