| Abstract | Suppose that a man is sitting in front of a computer calculating a function over its domain. In its simplest realization the program keeps printing out the samples of the domain with their respective function value in alphanumeric form. The user of the program who is mainly interested in the shape of the function has a very hard time reading all the data before they are scrolled o the screen, interpreting numbers like 1 : 2345e12, and constructing the shape in his mind. He would prefer the computer to create the drawing of the function itself, and not to bother him with a list of mind-boggling oating point n umbers. Assume that his dream comes true immediately, and the computer draws horizontal rectangles proportional to the function value, instead of printing them out in numeric form, making a histogram-like picture moving up as new values are generated. The user can now see the shape of a portion of the function. But is he satised? No. He also wants to have a look at the shape of larger parts of the function; he is not happy with the reduced accuracy caused by the limited resolution of the computer screen, meaning for example that two v alues that are very close to each other would share the same rectangle, and very large values generate rectangles that run o the screen. It irritates him that if he turns his head for just a second, he loses a great portion of the function, because it has already been scrolled o. The application of graphics instead of a numeric display has not solved many problems. |
