Since Rober Penner published the easing equations back in 2003, tweens have become very popular with flash workers and are taken for granted today.
But it has been brought to my attention that they are not that well known within 3D graphics applications – like C4D.
So Smart Tween was born – a C4D XPresso node that enables the animator to ease virtually any parameter or value with ten tween and four ramp types.
It features limited, delayed loops, pingpong and it previews the output curve.
