The Utah teapot, or the Newell teapot, is one of the standard reference test models in 3D modeling and an in-joke[1] within the computer graphics community. It is a mathematical model of an ordinary Melitta-brand teapot designed by Lieselotte Kantner [de] that appears solid with a nearly rotationally symmetrical body. Using a teapot model is considered the 3D equivalent of a "Hello, World!" program, a way to create an easy 3D scene with a somewhat complex model acting as the basic geometry for a scene with a light setup. Some programming libraries, such as the OpenGL Utility Toolkit,[2] even have functions dedicated to drawing teapots.

The teapot model was created in 1975 by early computer graphics researcher Martin Newell, a member of the pioneering graphics program at the University of Utah.[3] It was one of the first to be modeled using Bézier curves rather than precisely measured.
