Chapter 4

Interpolation-Based Animation

This chapter presents methods for precisely specifying the motion of objects. While the previous chapter presented basics of interpolating values, this chapter addresses how to use those basics to facilitate the production of computer animation. With these techniques, there is little uncertainty about the positions, orientations, and shapes to be produced. The computer is used only to calculate the actual values. Procedures and algorithms are used, to be sure, but in a very direct manner in which the animator has very specific expectations about the motion that will be produced on a frame-by-frame basis. These techniques are typified by the user setting precise conditions, such as beginning and ending values ...
