Sculpture focuses on creating an artwork by solving three-dimensional problems utilizing both traditional material values and modern technological innovations. A continuously evolving art form, it relies on the understanding of spatial relationships and the physical manipulation and transformation of materials. As a discipline, sculpture has changed and adapted over time in terms of materials, function, and relative status within the arts. The field of sculpture today relies on historical traditions and contemporary innovations, and its scope has widened dramatically as new materials, techniques, and concepts have been developed. Artists who embark on the study of sculptural forms are taught to develop practical and critical thinking skills while advancing their own aesthetic expression of contemporary and traditional sculptural practices.
