The example below shows four examples of defining a ball bouncing:
For each, the centre of the ball goes from -100 to 1300 in the X, and values 30;530;280;530;405;530;468;530;499;530;515 in the Y.
- linear speed (calcMode="linear")
- spline: the keyTimes are spread evenly across the X-direction while the spline curves have the ball speeding up and slowing down in each interval.
- similar to the previous one but an ellipse is substituted as it hits the ground
- just a slower motion version of the one before
Below is a much more effective demonstration produced by Antoine Quint showing the difference between linear and spline interpolation.
