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:
“Prosecutors insist they are mounting a “thorough investigation,” which sometimes means thorough and sometimes, historically, has meant long enough to let the fire burn down in an incendiary case. A thorough investigation is fine; an interminable one is disgraceful.”
—Anna Quindlen (b. 1952)
“The Yuppies are not defectors from revolt, they are a new race, assured, amnestied, exculpated, moving with ease in the world of performance, mentally indifferent to any objective other than that of change and advertising.”
—Jean Baudrillard (b. 1929)
“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)
