PolskiAurora Borealis & Starfield (2D)
A 2D canvas companion to the 3D aurora scene: animated gradient ribbons driven by the same double-sine wave math, a twinkling starfield, and periodic shooting stars — with live controls for intensity, speed, density and meteor frequency.
This 2D companion reproduces the 3D scene's aurora ribbons and starfield on a plain canvas: each aurora band is drawn as a filled, colour-graded path whose vertical offset follows the same two-term sine wave used in the original's vertex shader, twinkling stars pulse in brightness on a per-star sine cycle, and shooting stars spawn on a timer and fade out along a short trail. Sliders let you push the aurora amplitude and drift speed, change how many stars are drawn, control how often meteors appear, and swap the aurora's colour palette.
Canvas2D aurora and starfield simulation: wavy gradient ribbons driven by a two-term sine function, twinkling stars, and periodic shooting stars, with live sliders for intensity, speed, density and meteor frequency.
