Pictorial relief is a quality of visual awareness that happens when one looks into (as opposed to at) a picture. It has no physical counterpart of a geometrical nature. It takes account of cues, mentally identified in the tonal gradients of the physical picture-pigments distributed over a planar substrate. Among generally recognized qualities of relief are color, pattern, texture, shape, and depth. This review focuses on geometrical properties, the spatial variation of depth. To be aware of an extended quality like relief implies a "depth" dimension, a nonphysical spatial entity that may smoothly vary in a surface-like manner. The conceptual understanding is in terms of formal geometry. The review centers on pertinent facts and formal models. The facts are necessarily so-called brute facts (i.e., they cannot be explained scientifically). This review is a foray into the speculative and experimental phenomenology of the visual field.

图形浮雕的几何形状。

绘画浮雕是一种视觉感知的质量,当人们看着(而不是看着)图片时会发生。它没有几何性质的物理对应物。它考虑了提示,这些提示是在分布在平面基材上的物理图片颜料的色调渐变中从心理上确定的。通常公认的浮雕质量是颜色,图案,纹理,形状和深度。这篇综述着重于几何特性,深度的空间变化。要知道像浮雕这样的扩展质量意味着“深度”维度,这是一种非物理的空间实体,可以以类似表面的方式平滑地变化。概念上的理解是基于形式几何。审查的重点是有关事实和形式模型。事实必然是所谓的残酷事实(即,不能科学地解释它们)。
