In western painting it came from the primitive society when a few space factors appeared in the mural paintings sketched out by single line, the Greek bottle picture with the simple perspectivity, the Rome mural painting in which the perspectivity was originated, the Middle Ages when the perspectivity develop relatively slowly, the Renaissauce when the perspectivity highly developed, the Post Impressionism when Cezanne reformed the structure of space subjectively and orderly to open the gate of Modern Art, the 21 Century when the space was des-constructed and the idea of space developed pluratislically, at last the beginning of Actionism , to reach the end of the development of the space in painting, so to achieve the return from the three-dimensional illusion to the reality.

西方绘画由原始社会单线勾勒的壁画中极少的空间因素的运用，继而希腊瓶画中简单的透视。罗马时期透视法的萌芽，中世纪的相对滞缓的发展，文艺复兴时期对自然完善的表现至塞尚，则开启了现代艺术中空间主观化、秩序化的先河，进而出现二十世纪绘画空间解构、重组、多元化发展的状况，行为艺术的产生，实现了绘画空间由三维幻象到真实的还原，成为西方绘画的空间发展历程的终结点。
