We can also use splines to calculate orientations for objects in between their orientations at keyframe positions. This allows the motions of an object to be smooth rather than robot-like. In traditional animation, orientation animation required an artist to redraw the object when it rotated out of the plane of the platen (on the animation stand) and path animation was limited to repositioning the cells in X and Y (although the whole scene could be zoomed). In computer graphics, it is easy to rotate and reposition objects anywhere in three dimensions. That’s why you see so much of it!
