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:
“Well, “slithy” means “lithe and slimy.” “Lithe” is the same as “active.” You see, it’s like a portmanteau—there are two meanings packed up into one word.”
—Lewis Carroll [Charles Lutwidge Dodgson] (1832–1898)
“I leave the governor’s office next week, and with it public life ... [which] has been on the whole a pleasant one. But for ten years and over my salaries have not equalled my expenses, and there has been a feeling of responsibility, a lack of independence, and a necessary neglect of my family and personal interests and comfort, which make the prospect of a change comfortable to think of.”
—Rutherford Birchard Hayes (1822–1893)
“Men have defined the parameters of every subject. All feminist arguments, however radical in intent or consequence, are with or against assertions or premises implicit in the male system, which is made credible or authentic by the power of men to name.”
—Andrea Dworkin (b. 1946)
