Relief is carved out of the plane image of a sculpture bump ups and downs, is a cross between painting and sculpture in the round between artistic expression.
Relief of the three-dimensional space can be constructed three-dimensional shape can also be both a flat shape; either attached to a carrier, but also relatively independent existence. Generally speaking, in order to fit specific needs or decorative ornamental point of view needs, the relative relief is characterized by the prominent sculpture in the round shape after compression characteristics of two-dimensional or flat. Relief and sculpture in the round of the difference lies in its relative flatness and three-dimensional. It is a form of space between the paintings and a sculpture in the round two-dimensional virtual space has the so-called three-dimensional physical space between the compression space. Compression space relief space limits the freedom of development, relying on the flat background, the sculpture in the round of the weakened physical sense, and more adoption and use of drawing and perspective and the illusion of virtual learning to achieve the performance goal. Compared with the sculpture in the round, relief and more space in accordance with drawings and physical principles to deal with the relationship. However, reflecting the pursuit of the aesthetic image of the center, reliefs and sculpture in the round is exactly the same way in different forms of display only certain physical features. As one of the types of sculpture, relief sculpture showing first the general characteristics, that is, its visual and aesthetic effect is not only involved in resorting to touch. At the same time, it can play very well the art of painting in composition, subject matter and spatial processing, and other areas, the performance can not show the contents of the carvings and objects, such as the background of events and people and the environment, narrative and plot a continuous transition different time and space to switch perspectives, complex and diverse other things interspersed and overlapping. Plane carving and shaping, so that relief can be integrated sculpture and painting technology, to keep the way of diversity and diversification. Reduced two-dimensional space perspective, the background image depicts the main foil or virtual, so that relief of shape other than the language of sculpture, especially sculpture in the round, with a stronger narrative also lose the general performance of the sculpture.
Different levels of compression space, the formation of the two basic forms of relief - high relief and low relief.
High relief from the bit as high, thick, body compressed to a lesser extent, so the spatial structure and shape characteristics closer to sculpture in the round, and even some full use of sculpture in the round of local treatment approach. Often use three-dimensional high-relief undulating or exaggerated physical space to handle the formation of a sense of spatial depth and concentration of the strong visual impact, the relief image of the shape for the arts with a special performance of the force and charm. Paris Charles de Gaulle Square, famous buildings on the Arc de Triomphe relief, "starting in 1792," is a masterpiece of high relief. Relief sculpture in the round with the artist's handling of the combination to be successful, each stacked full demonstration of the wrong people, ups and downs of a complex hierarchy, gives a strong, blowing visual impact.
Bas-relief from the bit lower, larger body compression, strong graphic sense, greater close to the form of painting. It is not primarily rely on physical effects of space to create a space, make more use of means or painting depicting perspective, illusion and other more abstract approach to cause the compression space, which will help strengthen relief for the carrier dependent. Mesopotamia's ancient Assyrians, probably longer than most good means of artistic expression with this artist. In a series of "Assyrian hunting map", they use a good bas-relief techniques, full of rhythm and rhythm demonstrated vibrant artistic images, and complex momentum aptly show people and animals inner feelings.
Relief and reducing levels of choice, and to consider the performance of the object function, theme, location, and light and other environmental factors, including environmental and light plays a decisive role. Excellent sculptor always good to deal with these relationships, so that works to achieve good visual effects.
Fully express thoughts and feelings in the basic creation of aesthetic principles, different forms of relief have focused on the art of character or performance adaptability. Generally speaking, high relief the larger spatial depth and strong plastic, to give expression to their feelings solemn, calm, serious, deep effects and grand and imposing; bas-relief flowing to fill the gap places the painting of lines and Multi-view cut plane of the composition, convey the calm atmosphere and light music as lyrical romantic tenderness.
The development of sculpture in the round sculpture increasingly strengthened its relative independence, by contrast, although the more subject to one kind of relief dependency, that is "flat" or "wall" of dependence, but its unique performance characteristics and rich sculptural modeling tool is still the other art forms can not be replaced. Moreover, its aesthetic properties to promote the revolution in modern art, it is also increasingly strengthened its relative independence. Fixed "wall" of dependence and adaptation in the modern relief is no longer on the way as the classical relief seemed so to strong, stiff and can not be shaken. In terms of modern relief, as the carrier or the environment "wall" is a free, optional, and it therefore has the freedom to develop the vast space
