Spline interpolation is a mathematical method used in digital animation to create smooth transitions between keyframes by fitting piecewise polynomial functions, known as splines, to the control points. This technique allows animators to generate fluid motion and natural-looking animations by ensuring that the transition between different states is seamless and visually appealing. By using spline interpolation, animators can efficiently define complex motion paths without the need for manual frame-by-frame adjustments.
congrats on reading the definition of spline interpolation. now let's actually learn it.
