Bezier Keyframes

At this point, it should go without saying that a keyframe is a kind of frame in the same way that an address is a kind of dress... that is to say, it isn’t. In Blender, a keyframe is more like a little object that influences some property of something in your 3D scene. It exists outside the 3D Viewport in multiple areas; it takes the appearance of a point along a curve in the Graph Editor and a diamond-like shape in the Timeline and other editors. Its main attributes are value and time, which determine the value of an assigned property at a given frame, but it also possesses attributes such as interpolation and easing, which help determine the interpolated values between two keyframes.

There remains one special category of keyframe with its own particular attributes, which we left unexplored in the previous chapter: Bezier keyframes.

These keyframes are so powerful and potentially baffling that they deserve their own chapter in this book. Technically...
