Floating 3D Particles Demo 2

A standalone example that renders Floating3DParticles as a full-width, 500px-high background field. The particle color adapts to the active light or dark theme.

Installation

pnpm dlx shadcn@latest add @magicui/floating-3d-particles-demo-2

Requires @magicui in the registries of your components.json (shadcn adds official directory namespaces automatically).

Usage

usage.tsx
"use client"import { useTheme } from "next-themes"import { Floating3DParticles } from "@/registry/magicui/floating-3d-particles"export default function Example() {  const { resolvedTheme } = useTheme()  const color = resolvedTheme === "dark" ? "#c4b5fd" : "#6d28d9"  return (    <div className="bg-background relative h-[500px] w-full overflow-hidden rounded-lg border">      <Floating3DParticles color={color} depth={0.8} opacity={0.55} quantity={1000} />    </div>  )}
  • Use as a decorative animated background for hero sections, landing pages, and feature panels.
  • Use when the particle field should occupy a standalone bounded container rather than overlay page content.
  • Use for atmospheric visual styling that responds automatically to the user’s active theme.
  • Use as a starting point for experimenting with particle quantity, depth, opacity, and color.

Examples

Standalone light-theme background

Render the field with a fixed violet color in a bounded panel.

standalone-light-theme-background.tsx
import { Floating3DParticles } from "@/registry/magicui/floating-3d-particles"export default function LightParticleField() {  return (    <div className="relative h-[500px] w-full overflow-hidden rounded-lg border bg-background">      <Floating3DParticles color="#6d28d9" depth={0.8} opacity={0.55} quantity={1000} />    </div>  )}

Lower-density particle field

Use fewer particles for a quieter decorative background.

lower-density-particle-field.tsx
import { Floating3DParticles } from "@/registry/magicui/floating-3d-particles"export default function SparseParticleField() {  return (    <div className="relative h-[360px] w-full overflow-hidden rounded-lg border bg-background">      <Floating3DParticles color="#c4b5fd" depth={0.8} opacity={0.55} quantity={400} />    </div>  )}

Theme-aware particle field

Match the registry example’s light and dark particle colors using next-themes.

theme-aware-particle-field.tsx
"use client"import { useTheme } from "next-themes"import { Floating3DParticles } from "@/registry/magicui/floating-3d-particles"export default function ThemeAwareParticleField() {  const { resolvedTheme } = useTheme()  return (    <div className="relative h-[500px] w-full overflow-hidden rounded-lg border bg-background">      <Floating3DParticles        color={resolvedTheme === "dark" ? "#c4b5fd" : "#6d28d9"}        depth={0.8}        opacity={0.55}        quantity={1000}      />    </div>  )}

API reference

Accessibility

  • The demo contains no textual content or accessible label; the animated particle field should be treated as decorative.
  • If used behind meaningful content, keep that content in the DOM separately and ensure it remains readable against the animated background.
  • Respect reduced-motion preferences at the surrounding application level if the underlying particle component does not provide a reduced-motion option.
  • Maintain sufficient color contrast for any foreground text placed over the particle field.
