本文采用视觉、经验和形式化的方法（Li & Zaidi，Vision Research，40（2000）217; Li & Zaidi，Vision Research，41（22）（2001 a）2927）来检验定向纹理成分在传递朝向或远离观察者的凹表面和凸表面的真实感知中的作用。结果表明，对组件，定向对称的轴的最大曲率，联合收割机提供的测地线方向调制是至关重要的真实的形状感知。节距的程度决定了关键部件对的方向。透视对于凹凸的真实感知是至关重要的，无论音高的程度如何。本文的结果再次证实，真实的形状感知依赖于提取关键模式的定向能量，但也表明，一类纹理能够传达真实的感知一般的意见，可发展的形状是更严格的比李和Zaidi（美国光学学会杂志A，18（2001年b），2430）。
This paper uses visual, empirical and formal methods (Li & Zaidi, Vision Research, 40 (2000) 217; Li & Zaidi, Vision Research, 41 (22) (2001a) 2927) to examine the roles of oriented texture components in conveying veridical percepts of concave and convex surfaces that are pitched towards or away from the observer. The results show that pairs of components, oriented symmetrically around the axis of maximum curvature, combine to provide the geodesic orientation modulations that are critical for veridical shape perception. The degree of pitch determines the orientations of the critical pair of components. Perspective is crucial to the veridical perception of concavities and convexities, regardless of the degree of pitch. The results of this paper reconfirm that veridical shape perception depends on extracting critical patterns of oriented energy, but also show that the class of textures capable of conveying veridical percepts of developable shapes in general views is even more restricted than that identified by Li and Zaidi (Journal of Optical Society of America A, 18 (2001b), 2430).
