3D computer graphics
3D computer graphics are images (stills or animated) that are created with the use of the computer and of specific 3D softwares. Although the result is a 2D image, or a series of them, the process of creation involves the use of a the dimension of depth that, instead of being faked by the artist, can actually be calculated and computed by the machine and visually represented by the 3D software.
The process involves: modeling, texturing, lighting, animating, rendering (not necessarily in this order).
Curiosities: The teapot is probably the icon of 3D computer graphics. In 1974, Martin Newell, a British born computer scientist, was wondering what object to model in CG. He was living in Utah, at the time, and had just purchased a teapot with his wife Sandra in Salt Lake City. Following the suggestion of his wife, he decided to model that teapot in 3D as it was a common and easy to recognize object but also had a complex topology wich includes concave and convex surfaces. It also has surfaces inside, that are not visible. It was, at the time, a compelling experiment. The real teapot that inspired the Newells is now in the Computer History Museum in California.
