Utah teapot(Noun)

A three-dimensional mathematical model of a teapot, often used as a reference object to test or assess a rendering technique.

Utah teapot

This object is historically one of the first complex 3D models to be rendered in computer graphics. It consisted of about 110 vertices, and was generated by Martin Newell in 1974 using hand-drawn Bezier curves, based on a real teapot that he and his wife had bought. This model served as a basis for comparing various 3D rendering methodologies for lighting, textures, bump-mapping, etc. By the standards of 2002, the model is trivial to render and thus is often not suited to demonstrate the complexity of modern research. Despite this, the tea pot still appears, now and then, in recent papers. More on the teapot's history lives at The History Of The Teapot. Compare lenna, Stanford Bunny
