02 / Keyframes & independent tracks
The weight of a moment.
A sphere falls, compresses, and recovers. Scrub a single playhead while height, deformation and color follow their own tracks.
What this study teaches
A deterministic bounce evaluator maps the playhead to separate height, squash and color tracks. The impact keyframe is editable; the graph and sphere use the same evaluated values.
Independent implementation informed by “Animating a 3D Scene with Spline’s New Timeline Tool”, Maksim Borisov, Codrops. This is newly authored code and artwork, not a recovered original project. The article supplies no code blocks; derive behavior from the timeline/graph-editor explanation. Do not label the result a recovered Spline scene.
