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:
“Tolerance is a very dull virtue. It is boring. Unlike love, it has always had a bad press. It is negative. It merely means putting up with people, being able to stand things.”
—E.M. (Edward Morgan)
“I had heard so much about how hard it was supposed to be that, when they were little, I thought it would be horrible when they got married and left. But that’s silly you know. . . . By the time they grow up, they change and you change. Eventually, they’re not the same little kids and you’re not the same mother. It’s as if everything just falls into a pattern and you’re ready.”
—Anonymous Mother. As quoted in Women of a Certain Age, by Lillian B. Rubin, ch. 2 (1979)
“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)
