This document discusses visual shapes and forms, distinguishing between two-dimensional shapes and three-dimensional forms. It defines geometric shapes/forms as those made with straight lines and circles, while organic shapes/forms are found in nature. Costumes, settings, and actors' bodies can utilize both geometric and organic shapes and forms. Forms can change through a process called metamorphosis, as seen in nature and in theater through changes to actors' appearance. Designers may employ morphing techniques to visualize incremental changes between entities.
