The Teapot that Became the Standard in Computer Graphics

You might not know it, but there’s an incredibly famous teapot that has been in hundreds of films and TV in the past decades. Toy Story, The Simpsons, your old computer screensaver – all these things and more contained the same teapot hidden away.

This unassuming teapot dates back to 1974 and it is arguably the most influential object in computer graphics.

Computer scientist Martin Newell was a Ph.D. student at the University of Utah, which was a powerhouse of computer graphics in the 1970s. Newell had innovative ideas about how he could render 3D shapes in computer graphics with things like shadows, reflective textures, and obscure surfaces. The problem was, at the time, there wasn’t a digital object that Newell had access to test out his ideas.

Students and professors proposed objects like chess pawns, donuts or urns, but all were deemed too simple to test these new graphics methods on.

Newell struggled to find an object until one day while drinking tea with his wife, she proposed that he digitized the teapot they were using. The teapot was from a local department store and had all the necessary features: curves, a handle, a lid, and the spout, all covered in a reflective ceramic surface. It was perfect.

Newell quickly sketched out the pot with dimensions, and once he returned to his lab, he entered the coordinates to build the digital object using a method with Bézier control points on a Tektronix storage tube – an early type of computer graphics module. The end result was one of the most versatile and useful 3D models to date. However, Nowell’s original teapot wasn’t in its final form yet.

His colleague, Jim Blinn, adjusted the teapot’s height during a demonstration and decided he liked that version better. It was at this point that the Utah teapot was born…

Newell and his colleague Blinn used the teapot extensively for their own research, but they believed that it was important they shared their model publicly. At the time, other researchers were also starved for a versatile 3D model and the Utah teapot was perfect. The model was used so extensively that some researchers had even memorized the exact data points of the model.

In the close-knit computer graphics industry, the teapot quickly became a cherished staple. Anyone who had a new idea about computer graphics tested it out on the teapot first.

In modern times, the Utah teapot is legendary. It’s a built-in shape within most graphics software packages, and is still used for testing and demonstration. All this fame has led to the graphics community sneaking the teapot into films all over the place.

Martin Newell today has said that despite all of the innovations he’s worked on, he’ll unfortunately be remembered for “that damned teapot.”

The Utah teapot stands as a reminder today that sometimes simple objects can be the basis of future innovation.
