Elastic vector curves form the baseline of luxury digital design. Standard linear easing or even generic quadratic transitions feel robotic to the human eye. By implementing spring physics algorithms directly into canvas animations, we can evoke organic inertia.
Under the Hood: Spring Math
A classic spring animation is governed by a second-order linear differential equation: F = -kx - cv. In web animations, we compute the displacement and velocity dynamically at 60fps to mimic natural deceleration.
Implementing Custom Bezier Interpolations
If full physics scripts are too heavy, we can leverage customized Cubic Bezier easing functions like cubic-bezier(0.25, 1.5, 0.5, 1). This generates a tactile overshoot that simulates elastic tension.
Lottie Easing Integration
Within Adobe After Effects, ensure you adjust the speed and influence percentages in the Graph Editor. High speed initial vectors combined with high influence percentages result in ultra-premium kinetic timing when exported via Bodymovin/Lottie.
