What is Sculpture ?

Sculpture is three-dimensional artwork created by shaping or combining hard, plastic material, sound, text, light, commonly stone (either rock or marble), metal, glass, or wood. Some sculptures are created directly by finding or carving; others are assembled, built together and fired, welded, molded, or cast. Sculptures are often painted.[1]
Because sculpture involves the use of materials that can be moulded or modulated, it is considered one of the plastic arts. The majority of public art is sculpture. Many sculptures together in a garden setting may be referred to as a sculpture garden.
