虽然表面水平过程的作用已经被证明，视觉插值模型往往强调轮廓关系。我们报告了两个实验的几何约束管理3D插值曲面片之间没有可见的边缘。观察员被要求分类对平面补丁指定的随机点的差异和可见通过圆孔（对齐或未对齐）在frontoparallel遮挡。在每次试验中，表面出现在平行或收敛的平面与垂直（实验1）或水平（实验2）倾斜和变量的倾斜。我们预计分类任务时，被认为是连接的补丁。我们发现3D相关与非相关补丁的灵敏度和速度有所提高。这里，3D相关性不涉及定向边缘，而是诱导从立体信息计算的贴片的定向。性能显着影响倾斜各向异性：灵敏度和速度都较差的水平倾斜补丁。我们发现几乎相同的3D性能相关性的优势，这表明一个各向同性的单位形成过程。结果被解释为证据表明，诱导倾斜约束表面插值在没有明确的边缘信息：3D轮廓和表面插值过程中共享共同的几何约束形式化的3D相关性。
Although the role of surface-level processes has been demonstrated, visual interpolation models often emphasize contour relationships. We report two experiments on geometric constraints governing 3D interpolation between surface patches without visible edges. Observers were asked to classify pairs of planar patches specified by random dot disparities and visible through circular apertures (aligned or misaligned) in a frontoparallel occluder. On each trial, surfaces appeared in parallel or converging planes with vertical (in Experiment 1) or horizontal (in Experiment 2) tilt and variable amounts of slant. We expected the classification task to be facilitated when patches were perceived as connected. We found enhanced sensitivity and speed for 3D relatable vs. nonrelatable patches. Here 3D relatability does not involve oriented edges but rather inducing patches' orientations computed from stereoscopic information. Performance was markedly affected by slant anisotropy: both sensitivity and speed were worse for patches with horizontal tilt. We found nearly identical advantages of 3D relatability on performance, suggesting an isotropic unit formation process. Results are interpreted as evidence that inducing slant constrains surface interpolation in the absence of explicit edge information: 3D contour and surface interpolation processes share common geometric constraints as formalized by 3D relatability.
