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:
“They tell us that women can bring better things to pass by indirect influence. Try to persuade any man that he will have more weight, more influence, if he gives up his vote, allies himself with no party and relies on influence to achieve his ends! By all means let us use to the utmost whatever influence we have, but in all justice do not ask us to be content with this.”
—Mrs. William C. Gannett, U.S. suffragist. As quoted in History of Woman Suffrage, vol. 5, ch. 8, by Ida Husted Harper (1922)
“Dylan is to me the perfect symbol of the anti-artist in our society. He is against everythingthe last resort of someone who doesnt really want to change the world.... Dylans songs accept the world as it is.”
—Ewan MacColl (19151989)
“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)
