This document provides an introduction to 3-dimensional design, covering key definitions, elements, principles, and interpretive techniques. It discusses how 3D design differs from and is similar to 2D design. The core elements of 3D design - line, plane, volume, mass, space, texture, light, color, and time - are defined. Principles for organizing 3D forms such as containment, proximity, and balance are also outlined. The document provides examples of works to illustrate concepts and closes by describing approaches to interpreting 3D artwork.
