Star Field
A layered, twinkling deep-space star field with drifting nebula color washes, mouse-driven ripples, and occasional shooting stars trailing across the void.
Build a self-contained, performant Canvas 2D visual effect in a single React + TypeScript component.
Effect: "Star Field".
Description: A layered, twinkling deep-space star field with drifting nebula color washes, mouse-driven ripples, and occasional shooting stars trailing across the void.
Current settings: star density = 70, twinkle speed = 1, shooting-star rate = 1, color = Single, hue = 220, second hue = 290.
Tags: space, stars, ambient, background, particles.
Requirements:
- Use requestAnimationFrame with a delta-time (dt) step, clamped to avoid jumps on tab switches.
- Render crisply: fully clear the canvas every frame (clearRect). Do NOT fake motion blur by painting a translucent background each frame, because that causes permanent 8-bit "ghost" burn-in. If you want trails, store each particle's recent positions and draw them as an explicit fading tail.
- If many short-lived particles are spawned, use an object pool (pre-allocate, reuse, swap-remove on death) to avoid GC pauses.
- Scale the backing store by devicePixelRatio (cap ~2) and handle resize.
- Pause when the tab is hidden or the canvas is off-screen; respect prefers-reduced-motion.
- Expose the listed settings as adjustable props/controls.
