552 Chapter 6 Keyframes and Curves
Generate Keyframes
Ordinarily the extrapolation occurs without actually creating any new keyframes. This
lets you experiment with different methods. However, you can convert an extrapolation
method into actual keyframes so you can further manipulate them. This is done using
the Generate Keyframes command. You can choose how many of the extrapolation
cycles you want converted into keyframes. Cycles after the number you chose are left
in the extrapolated state.
Repeat Duplicates the curve, applying it again
and again.
Progressive Extends the curve by repeating the
existing shape of the curve, but rather
than returning to the exact same values,
it begins again from the existing end
value.
