Giotto di Bondone (1267–1337) is credited with first treating a painting as a window into space, but it was not until the demonstrations of architect Filippo Brunelleschi (1377–1446) and the subsequent writings of Leon Battista Alberti (1404–1472) that perspective was formalized as an artistic technique.

(1267至1337)被认为是第一个将绘画看作表达空间的窗口的人，但是，直到有了菲利波布鲁内列斯基(1377至1446)的示范和利昂纳巴蒂斯塔阿尔贝蒂）(1404至1472)随后的作品，透视法才作为一种艺术技巧正式确定其地位。

诸如玻璃电热烧锅、玻璃电热暖锅，玻璃电热牛奶杯、玻璃电热恒温电饭包、玻璃电热烤炉等一种放射线诊断时用的射线防护装置，包括方孔限光板（4）、圆孔限光板（1）、伺服电机、上限位开关（3）、下限位开关（7）等，装设在活动床球管遮光器前，依靠伺服电机上下限位开关及控制电路进行连锁控制，自动变换圆孔限光板的位置，将透视和点片时的多余射线遮挡住，使患者和医生都得到可靠的防护。

To them, the west sought too much to render 'the external appearance and relief of forms', and they rebuked westerners for exaggerated use of light and shade in their continual striving after effect in perspective and chiaroscuro.

对这些画论家来说，西方的艺术太「著重事物的外观和立体表面」。他们批评西方的画家因为受透视法和明暗对照法这两种理论影响，把画面的光度和阴影层次过度夸大。
