The Utah teapot or Newell teapot is a 3D model which has become a standard reference object (and something of an in-joke) in the computer graphics community.
The teapot shape contains a number of elements that made it ideal for the graphics experiments of the time — it is round, contains saddle points, has a genus greater than zero because of the hole in the handle, can project a shadow on itself, and looks reasonable when displayed without a complex surface texture.
Jim Blinn (in one of his "Project Mathematics!" videos) proves an interesting version of the Pythagorean theorem: Construct a (2D) teapot on each side of a right triangle and the area of the teapot on the hypotenuse is equal to sum of the areas of the teapots on the other two sides.

The Utah teapot is a 3D model which has become a standard reference object (and something of an in-joke) in the computer graphics community.
The teapot was created in 1975 by early computer graphics researcher Martin Newell, a member of the pioneering graphics programme at the University of Utah.
The common (rather squat) appearance of the teapot differs from the Melita original, reportedly because Newell's colleague Jim Blinn transformed it to compensate for the non-square pixels on his early frame buffer.

Newell made the mathematical data that describes the teapot's geometry (a set of three-dimensional coordinates) publicly available, and soon other researchers began to use the same data for their computer graphics experiments.
Although technical progress has meant that the act of rendering the teapot is no longer the challenge it was in 1975, the teapot continued to be used as a reference object for increasingly advanced graphics techniques.
The original teapot model was never intended to be seen from below and had no surface to represent the base of the teapot; later versions of the data set have fixed this.

The Utah Teapot was the first computer graphics object to be designed and rendered as sculptured surfaces, rather than as a set of polygons.
The intersection between the spout and the body of the teapot was left implicit.
However, the very slightly four-lobed cross-sectional shape of the teapot was as close as a cubic Bezier curve could come to representing a circular cross section, reflecting the inability of non-rational Bezier curves to represent conic sections such as circles.

A teapot is a vessel in which to brew tea leaves with boiling water, either inside a tea bag or loose, in which case a tea strainer will be needed to catch the leaves when the tea is poured.
Teapots usually have an opening on the top with lid where the tea and water are added, and a spout through which the tea can be poured.
Teapots should never be washed in a dishwasher or soapy water.

The teapot was made to sneeze by briefly softening the ceramic material, then stiffining it again abruptly.
The stiffness of the teapot was limited by the computation required for a stiff system of differential equations.
The teapot was seeded with random variations in the breakage threshold to create the effect of random defects in the material.

It is noticeably taller than the Utah teapot, because Newell's frame buffer used nonsquare pixels.
Rather than distorting the image, Newell's colleague Jim Blinn reportedly scaled the geometry to cancel out the stretching, and when the model was shared with users of other systems, the scaling stuck.

Utah Senator Reed Smoot contributed to the development of public land and conservation policy during the twenty-eight years (1905-1933) he served on the Senate Committee on Public Lands and Surveys.
In Utah, the combination of environmental awareness and state regulations has resulted in the closing of nearly a hundred open dumps that have long polluted the land, air, and surface and ground water.
Today, Utah has strict regulations for storing, treating, transporting, and disposing of hazardous waste, though some have questioned the relatively low fees required for such storage and wonder whether states with higher fees like California might use Utah as a dumping ground for their hazardous wastes.

 The Teapot - boakes.org
This “Utah Teapot”, as it is most commonly known, was digitally modelled by Martin Newell circa 1974 and was the first model to use bezier curves to form sculptured surfaces rather than being composed of a set of interlocking polygons.
A curiosity of the teapot is that the digital model is most commonly rendered at two thirds of it’s real height because when it was originally modelled computer monitor pixels were rectangular, not square - so digital versions appear more squat than the original teapot.
The original teapot now lives in Silicon Valley and is on display in the Computer History Museum in Mountain View, though I question the wisdom of storing such a historical piece of crockery so close to the San Andreas fault.

In order to lessen the heat loss when in use, the teapot needs to be generally close to spherical (a sphere has the minimum surface area for a given volume as we all remember from high school geometry).
To achieve a quick pour teapot, make sure that the total area of the holes in sieve far exceed the area of pouring end of spout.
