Use of Keyframes As A Means To Change Parameters
In software packages that support animation, especially 3D graphics packages, there are many parameters that can be changed for any one object. One example of such an object is a light. (In 3D graphics, lights function similarly to real-world lights: They cause illumination, cast shadows, and create specular highlights.) Lights have many parameters including light intensity, beam size, light color, and the texture cast by the light. Supposing that an animator wants the beam size of the light to change smoothly from one value to another within a predefined period of time, that could be achieved by using keyframes. At the start of the animation, a beam size value is set. Another value is set for the end of the animation. Thus, the software program automatically interpolates the two values, creating a smooth transition.

Famous quotes containing the words means, change and/or parameters:
“This soul, or life within us, by no means agrees with the life outside us. If one has the courage to ask her what she thinks, she is always saying the very opposite to what other people say.”
—Virginia Woolf (1882–1941)
“If we confine ourselves to one life role, no matter how pleasant it seems at first, we starve emotionally and psychologically. We need a change and balance in our daily lives. We need sometimes to dress up and sometimes to lie around in torn jeans. . . . Even a grimy factory can afford some relief from a grimy kitchen and vice versa.”
—Faye J. Crosby (20th century)
“What our children have to fear is not the cars on the highways of tomorrow but our own pleasure in calculating the most elegant parameters of their deaths.”
—J.G. (James Graham)
