Sculpture is defined as three-dimensional artwork that is created through various processes such as carving, modeling, casting, constructing, and assembling. Historically, sculpture was representational and static, but modern sculpture has expanded to include both representational and abstract forms that can be static, kinetic, or interactive. The main types of sculpture include works that are carved, modeled, cast, constructed, assembled, kinetic, site-specific/environmental, and installations. Sculpture is created using a variety of materials and techniques.
