The Utah teapot is a 3D model created in 1975 by Martin Newell and is the first complex 3d model ever created on a computer. It is a simple, round, partially concave mathematical model of an ordinary teapot. Since then, it has become a standard reference object in the computer graphics community and made several appearances as an in-joke in computer animated films like Toy Story or an episode of the Simpsons.
The objective of Utanalog by Unfold is to return the iconographic teapot to its roots as a piece of functional dishware while showing its status as an icon of the digital world.
Next to the Utanalog Unfold presents an animation about the history of the Utah teapot.

History of the Utah teapot
“The Utah teapot is a 3D model which has become a standard reference object in the computer graphics community. It is a simple, round, partially concave mathematical model of an ordinary teapot.
The teapot data was created in 1975 by early computer graphics researcher Martin Newell, a member of the pioneering graphics program at the University of Utah. Newell needed a moderately simple mathematical model of a familiar object for his work, and his wife's teapot (a Melitta) provided a convenient solution. The shape contains a number of elements that make it ideal for the graphics experiments of the time - it's round, contains saddle-points, has a concave element (the hole in the handle), and looks reasonable when displayed without a complex surface texture.
Newell made the mathematical data which describes the teapot's geometry (largely a set of three-dimensional coordinates) publicly available, and soon other researchers began to use the same data for their computer graphics experiments. These researchers needed something with roughly the same characteristics that Newell had, and using the teapot data meant they didn't have to laboriously enter geometric data for some other object. Although technical progress meant that the simple act of rendering the teapot was no longer the challenge it was in 1975, the teapot continued to be used as a reference object for increasingly advanced graphics techniques. The common (rather squat) appearance of the teapot differs from the Melitta original, reportedly because Newell's colleague Jim Blinn transformed it to compensate for the non-square pixels on his early frame buffer.”
“With the advent first of computer generated short films, and then of full length feature films, it has become something of an in-joke to hide a Utah teapot somewhere in one of the film's scenes. For example, in the movie Toy Story the Utah teapot appears in a short tea-party scene. The Utah teapot sometimes appears in the "Pipes" screensaver shipped with Microsoft Windows. The teapot also appears in The Simpsons episode Treehouse of Horror VI. Homer arrives accidentely in the 3d world, this world features common 3d primitives like cones, cylinders, pyramids, a grid and: the Utah.”
The Utah is most famous among motion artists and industrial designers because of its widespread use in 3d modeling software like AutoCAD, POV-Ray, OpenGL, Direct3D, and 3D Studio Max. In 3D Studio Max, one of the most commonly used packages, teapot can be found in several places. The “Teapotaëder” is one of the ten primitives available, besides the cube, sphere, cylinder, etc. As a result, every designer can use the Utah as a royalty free model. It is also use as an icon for the various rendering settings.
The Utah teapot is a well known virtual object but the history behind it is rarely known.
