Suppose we wish to animate a bouncing ball. We are given keyframes for the ball's motion. The
key frames are at times Tf={0,1,2,3,4,5,6}, with associated height values of
Hf={0,5,8,9,8,5,0}.
a) Plot the graph of height versus time using linear interpolation between key frames.
b) Give an equation for the height h(t) over the interval t=4...5 using linear interpolation.
c) In general, suppose we are given times Tf={t0,t1}, and associated heights Hf={h0,h1}, what is the equation for h(t) in the interval t0,t1 using linear interpolation?
d) Suppose we wish to achieve a smoother animation by using Catmull-Rom interpolation. What would the parametric derivatives of the interpolated curve be at t=4 and t=5?
e) Give 2D cubic Bezier control points for a Hermite interpolation given two sequential points (t0,h0) and (t1,h1) with associated derivatives (v0,v1).
