=== Interpolation ===
3D animation software interpolates between keyframes by generating a [[Spline (mathematics)|spline]] between keys plotted on a graph which represents the animation. Additionally, these splines can follow [[Bézier curve]]s to control how the spline curves relative to the keyframes. Using interpolation allows 3D animators to dynamically change animations without having to redo all the [[Inbetweening|in-between]] animation. This also allows the creation of complex movements such as ellipses with only a few keyframes. Lastly, interpolation allows the animator to change the framerate, timing, and even scale of the movements at any point in the animation process.
