ασυνεχής παρεμβολή(One of three methods used to describe how an animation transitions between values over its duration. This method produces a jump from one value to the next, without generating in-between values)
γραμμική παρεμβολή(One of three methods used to describe how an animation transitions between values over its duration. This method produces a constant rate of change)
παρεμβολή καμπύλης spline(One of three methods used to describe how an animation transitions between values over its duration. This method uses a Bezier curve to describe how the animation transitions between key frames. The Bezier curve starts at zero, which corresponds to the current key frame value, and ends at one (the next key frame's value). By altering the curve's two control points, you alter the animation's progress curve)
