A brush-stroke clip-path wipe paints in a gradient panel and a short word, holds, then fades and repeats. Click to paint it again, and set the text, pace, and edge softness.
Build a self-contained, performant Canvas 2D visual effect in a single React + TypeScript component.
Effect: "Watercolor Reveal".
Description: A brush-stroke clip-path wipe paints in a gradient panel and a short word, holds, then fades and repeats. Click to paint it again, and set the text, pace, and edge softness.
Current settings: text = "Bloom", duration = 1.6, edge softness = 0.5, auto loop on, color = Dual, hue = 280, second hue = 190.
Tags: CSS, clip-path, reveal, loop, click, text.
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.
