What term describes the shape of a piece of artwork that is often used in sculpture?

The term "form" in the context of sculpture refers to the three-dimensional shape and structure of an artwork. It encompasses the volume and mass of the sculpture, allowing it to occupy space and have physical presence. Understanding form is crucial when analyzing or creating sculptures because it dictates how the piece interacts with light, perspective, and the viewer's experience as they move around it. Form can be geometric or organic, and it plays a significant role in conveying the intended message or emotion of the artwork. The consideration of form is fundamental in sculpture, as it distinguishes three-dimensional works from two-dimensional ones where "line" refers to contour, and "color" pertains to hue and saturation. "Texture," on the other hand, describes the surface quality, which, while integral to a sculpture's overall feel and aesthetics, is not synonymous with the overall shape or structure defined by form.
