The Utah teapot has been the symbol of computer graphics. It was originally created by Martin Newell in 1975, when he was a PhD student at the University of Utah. Later on Jim Blinn, when he was a PhD student at the University of Utah, modified the shape of the teapot model by vertically scaling it. This modified version of the teapot is ubiquitous in computer graphics.
Every year at the university of Utah we hold the Teapot Rendering Competition to commemorate the Utah Teapot with images generated using renderers written by students.
