Its ability to explain the Earth’s geologic processes without reference to the Bible and its emphasis on an immensely long, cyclical process of erosion, deposition, sedimentation, and volcanic upthrust were revolutionary.
The Utah teapot (image shown is a modern rendering) is a 3D model which has become a standard reference object in the computer graphics community. It is a simple, round, partially concave mathematical model of an ordinary teapot.
The teapot data was created in 1975 by early computer graphics researcher Martin Newell, a member of the pioneering graphics program at the University of Utah. Newell needed a moderately simple mathematical model of a familiar object for his work, and his wife’s teapot (a Melitta) provided a convenient solution. The shape contains a number of elements that make it ideal for the graphics experiments of the time - it’s round, contains saddle-points, has a concave element (the hole in the handle), and looks reasonable when displayed without a complex surface texture.
The original teapot is on display at the Computer Museum, Boston
A Critical History of Computer Graphics and Animation
The Sketchpad system uses drawing as a novel communication medium for a computer. The system contains input, output, and computation programs which enable it to interpret information drawn directly on a computer display. It has been used to draw electrical, mechanical, scientific, mathematical, and animated drawings; it is a general purpose system. Sketchpad has shown the most usefulness as an aid to the understanding of processes, such as the notion of linkages, which can be described with pictures. Sketchpad also makes it easy to draw highly repetitive or highly accurate drawings and to change drawings previously drawn with it. The many drawings in this thesis were all made with Sketchpad.
A Sketchpad user sketches directly on a computer display with a “light pen.” The light pen is used both to position parts of the drawing on the display and to point to them to change them. A set of push buttons controls the changes to be made such as “erase,” or “move.” Except for legends, no written language is used.
