Floating 3D Particles

A client-side canvas component that renders a continuously rotating, perspective-projected field of floating particles. It supports configurable particle density, color, size, opacity, drift, and 3D depth while pausing off-screen and respecting reduced-motion preferences.

Usage

usage.tsx

import { Floating3DParticles } from "@/components/ui/floating-3d-particles"export function Example() {  return (    <section className="relative min-h-[400px] overflow-hidden rounded-xl bg-slate-950">      <Floating3DParticles color="#8B5CF6" quantity={300} depth={0.7} />      <div className="relative z-10 flex min-h-[400px] items-center justify-center">        <h1 className="text-4xl font-bold text-white">Build something remarkable</h1>      </div>    </section>  )}

Add an ambient animated background to hero sections, landing pages, dashboards, or feature panels.
Use behind foreground content when a decorative, non-interactive visual layer is needed.
Adjust quantity, depth, drift, and color to match a product theme or brand palette.
Prefer it for visual atmosphere rather than conveying essential information.

Examples

Hero background

Use the particle field as a decorative layer behind hero content.

hero-background.tsx

import { Floating3DParticles } from "@/components/ui/floating-3d-particles"export function Hero() {  return (    <section className="relative min-h-screen overflow-hidden bg-black">      <Floating3DParticles quantity={400} color="#8B5CF6" />      <div className="relative z-10 flex min-h-screen items-center justify-center">        <h1 className="text-5xl font-bold text-white">The future is floating</h1>      </div>    </section>  )}

Branded feature panel

Customize the particle color and depth for a themed product section.

branded-feature-panel.tsx

import { Floating3DParticles } from "@/components/ui/floating-3d-particles"export function FeaturePanel() {  return (    <div className="relative overflow-hidden rounded-2xl bg-indigo-950 p-8">      <Floating3DParticles color="#22D3EE" quantity={220} size={4} depth={0.8} drift={0.4} />      <div className="relative z-10">        <p className="text-cyan-300">Realtime analytics</p>        <h2 className="mt-2 text-3xl font-semibold text-white">See every signal</h2>      </div>    </div>  )}

Subtle low-density decoration

Reduce opacity and quantity for a restrained ambient effect behind content.

subtle-low-density-decoration.tsx

import { Floating3DParticles } from "@/components/ui/floating-3d-particles"export function AmbientCard() {  return (    <div className="relative overflow-hidden rounded-xl border bg-background p-6">      <Floating3DParticles quantity={120} color="#F59E0B" size={3} opacity={0.16} drift={0.25} />      <div className="relative z-10">        <h3 className="font-semibold">Quiet motion</h3>        <p className="mt-2 text-muted-foreground">A subtle animated backdrop for supporting content.</p>      </div>    </div>  )}

API reference

PropTypeDefaultDescription

quantitynumber400Number of particles on desktop. On viewports narrower than 768px, the count is scaled to 20%.

colorstring"#8B5CF6"Particle color as a 3- or 6-digit hexadecimal string. Invalid values fall back to the default purple RGBA color.

sizenumber5Mean particle radius in pixels. Individual particles vary by ±40%.

opacitynumber0.3Mean particle opacity from 0 to 1. Individual particles vary by ±0.2 and are clamped to that range.

driftnumber0.8Vertical movement per frame. Positive values move particles upward; negative values move them downward.

depthnumber0.53D depth intensity from 0 to 1. Zero produces a flat projection; one produces stronger perspective scaling.

classNamestring—Additional class names merged with the default absolute, full-size, pointer-events-none canvas classes.

styleReact.CSSProperties—Inline styles applied to the canvas element.

...canvasPropsReact.CanvasHTMLAttributes<HTMLCanvasElement>—All other native canvas HTML attributes and event handlers are accepted. The width and height attributes are omitted from the component API because the canvas dimensions are managed from its rendered size and device pixel ratio.
