The object is processed by compression, and the three-dimensional space is represented by factors such as perspective, and only one or two sides can be viewed. Reliefs are generally attached to another plane, so they are used more in architecture and can often be seen on utensils. Due to its compression characteristics, it occupies a small space, so it is suitable for decoration in a variety of environments. In recent years, it has taken an increasingly important position in the urban beautification environment. The relief sculpture is as colorful as the round sculpture in content, form and material. It mainly has several forms such as shrine-style, high-relief, bas-relief, line carving, and hollow style. 3. The relief that removes the bottom plate is called openwork (openwork carving). The so-called embossed bottom plate is removed, so as to produce a variety of negative space, and make the contour lines of the negative space and the positive space have a mutual conversion rhythm. This technique used to be used on door and window railing furniture, and some can be viewed on both sides.
