Did You Know?

In mathematics, interpolation lets you estimate values in a function or series between two known values. That helps identify values that don't really exist but usually are reasonable enough approximations to act as quantified data.

Flash works on the same basic paradigm. You define the general makeup of a shape at two points on the timeline, and Flash interpolates the position or characteristics of a shape for each frame that falls in between. The values aren't actual characteristics you specifically applied for that frame, but rather the Flash interpretations for that particular point in time.

And although the premise might seem painfully simple, the results are not. Most Flash animations and effects available on the Web today still use interpolation as a foundation. True, Flash can do a great deal more, particularly with the introduction of better ActionScript syntax. But even the most progressive ideas can leverage the Flash engine's capability to compile results on its own between two points.

And so like any other discipline you might labor to master, becoming comfortable with and—more importantly—understanding the theory behind this fundamental is vital. From the basic motion tween to some of the advanced effects in the next chapter, you're likely to apply these lessons more than any others found in the Flash 5 arsenal.
