The Utah Teapot

The Utah Teapot is a landmark computer-graphics model, first created by Martin Newell at the University of Utah and introduced to the graphics community in 1976. Its Bézier-patch construction made it an early example of modeling curved surfaces, and its distinctive shape became a standard test object for rendering and modeling techniques. It has since appeared in software, graphics APIs, research papers, films, games, and art. The model’s history also reflects changing technical goals: Jim Blinn scaled Newell’s taller original to the familiar shorter form; Frank Crow added a rounded bottom; Hank Driskill created a solid version with a round body and interior; and Russ Fish refined that interior.

The current collection offers downloadable models and interactive controls for viewing or customizing different versions, including mesh format, orientation, wireframe, components, caps, and texture-coordinate layouts. The 2026 version by Cem Yuksel reduces the interior to 30 added patches, for 62 total, while improving surface smoothness: curvature continuity makes reflections less abrupt, and small chamfers smooth the joins between the body, handle, and spout. Earlier versions vary in shape, bottom design, and interior detail, making the collection useful for comparing the model’s evolution. Files are available for commercial and other uses without charge; users are asked to retain the Utah Teapot name or identify derivatives as modified versions and credit the University of Utah’s historical model.
