The spatial structure of relief can be a three-dimensional form or a plane form; It can not only be attached to a certain carrier, but also exist relatively independently. Generally speaking, in order to meet the viewing or decoration needs of specific viewpoints, the prominent feature of relief relative to round sculpture is the two-dimensional or plane characteristics after shape compression. The difference between relief and round sculpture lies in its relative planarity and three-dimensional.

它的空間形態是介于繪畫所具有的二維虛擬空間與圓雕所具有的三維實體空間之間的所謂壓縮空間。壓縮空間限定了浮雕空間的自由發展，在平面背景的依托下，圓雕的實體感減弱了，而更多地采納和利用繪畫及透視學中的虛擬與錯覺來達到表現目的。與圓雕相比，浮雕多按照繪畫原則來處理空間和形體關系。

Its spatial form is the so-called compressed space between the two-dimensional virtual space of painting and the three-dimensional solid space of round sculpture. Compressed space limits the free development of relief space. Relying on the plane background, the sense of entity of round sculpture is weakened, and more virtual and illusion in painting and perspective are adopted and used to achieve the purpose of expression. Compared with round sculpture, relief mostly deals with the relationship between space and form according to the principles of painting.

但是，在反映審美意象這一中心追求上，浮雕和圓雕是完全一致，不同的手法形式所顯示的只是某種外表特征。作為雕塑藝術的種類之一，浮雕表現出雕塑藝術的一般特征，即它的審美效果不但訴諸視覺而且涉及觸覺。

However, in reflecting the central pursuit of aesthetic image, relief and round sculpture are completely consistent, and different techniques and forms show only some appearance characteristics. As one of the types of sculpture art, relief first shows the general characteristics of sculpture art, that is, its aesthetic effect not only appeals to vision, but also involves touch.

與此同時，它又能很好地發揮繪畫藝術在構圖、題材和空間處理等方面的優勢，表現圓雕所不能表現的內容和對象，譬如事件和人物的背景與環境、敘事情節的連續與轉折、不同時空視角的自由切換、復雜多樣事物的穿插和重疊等。

At the same time, it can give full play to the advantages of painting art in composition, theme and space processing, and show the contents and objects that the round sculpture cannot show, such as the background and environment of events and characters, the continuity and turning of narrative plot, the free switching of different time and space perspectives, the insertion and overlap of complex and diverse things, etc.

平面上的雕鑿與塑造，使浮雕可以綜合雕塑與繪畫的技術優勢，保持手法上的多樣性和多樣化。二維空間中的透視縮減，陪襯主體形象的背景刻畫或虛擬，使浮雕的塑造語言比之其它雕塑尤其是圓雕，具有更強的敘事性同時也不失一般雕塑的表現性。

The carving and shaping on the plane can integrate the technical advantages of sculpture and painting, and maintain the diversity and diversification of techniques. The reduction of perspective in two-dimensional space and the background depiction or virtualization of the main image make the modeling language of relief more narrative than other sculptures, especially round sculptures, without losing the expressiveness of general sculptures.
