The teapot is now usually available in rendering or modeling programs along with other geometric primitives, such as spheres, cubes, tori, etc. The story goes that Newell drew a teapot he had at home and digitized these drawings to create the model we know today as the Utah Teapot (figure 1). Capturing data in this way is called digitizing"). It may be used to trace an image from a piece of paper laid on the surface. Most models had to get their points entered in the computer program by hand or with a graphics tablet ("a computer input device that allows hand-drawn images and graphics to be input. In these days of age, very few models where available to the computer graphics community and creating them was also far from easy. In 1975, computer researcher Martin Newell needed a new 3D model for his work. Figure 1: Newell's original drawing of the teapot.
