![]() Following that, he went back to the computer laboratory and edited bézier control points on a Tektronix storage tube, again by hand. He sketched the teapot free-hand using graph paper and a pencil. His wife, Sandra Newell, suggested modelling their tea set since they were sitting down for tea at the time.

History The actual Melitta teapot that Martin Newell modelled, displayed at the Computer History Museum in Mountain View, California (1990–present) External imageĪ scan of the original diagram Martin Newell drew up, to plan the Utah Teapot before inputing it digitally. It was one of the first to be modeled using bézier curves rather than precisely measured. ![]() ![]() 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. Some programming libraries, such as the OpenGL Utility Toolkit, even have functions dedicated to drawing teapots. 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. It is a mathematical model of an ordinary Melitta-brand teapot that appears solid with a nearly rotationally symmetrical body. The Utah teapot, or the Newell teapot, is a 3D test model that has become a standard reference object and an in-joke within the computer graphics community.
