React Particles WebGL

A 2D/3D particle library built with React, Three.js and WebGL

react-particles-webgl was inspired by the popular particles.js library and built with react-three-fiber to offer smooth 60FPS high-count particle fields in both two and three dimensions.

Documentation https://timellenberger.com/libraries/react-particles-webgl

Config Generator https://timellenberger.com/particles

Code Sandbox Demos

npm NPM PRs Welcome Travis (.org)

2D "Particles.js" Canvas 3D Particle Field

Features

  • Simple drop-in usage, plays nice with SSR (the demo is running Next.js)
  • Smooth 60FPS particles and lines via WebGL
  • Full Three.js OrbitControls for extreme (optional) scene interactivity
  • Highly customizable particles and lines

Install

yarn add react-particles-webgl three

Usage

import React from 'react';
import ParticleField from 'react-particles-webgl';

/**
 * The default configuation for the ParticleField component
 *
 * Any option passed in via props will overwrite the default config
 */
const config = {
  // Display reference cube, useful for orienting the field
  showCube: true,
  // '2D' or '3D' particle field
  dimension: '3D',
  // 'bounce' or 'passthru'
  // 'bounce' will make particles behave like balls thrown at a wall when hitting canvas boundaries
  // 'passthru' particles will disappear after hitting canvas boundaries and be added back into the scene elsewhere
  boundaryType: 'bounce',
  // Maximum velocity of particles
  velocity: 2,
  // Toggles antialiasing -- must be set during construction, cannot be changed after initial render
  // Slight performance optimization to set false, although lines will appear more jagged
  antialias: false,
  // Min/Max multipliers which constraint how particles move in each direction
  // The default values here allow for particles to move in completely random x, y, z directions
  // See the "Snowfall" preset for an example of how to use these values
  direction: {
    xMin: -1,
    xMax: 1,
    yMin: -1,
    yMax: 1,
    zMin: -1,
    zMax: 1
  },
  lines: {
    // 'rainbow' or 'solid' color of lines
    colorMode: 'rainbow',
    // Color of lines if colorMode: 'solid', must be hex color
    color: '#351CCB',
    // Transparency of lines
    transparency: 0.9,
    // true/false limit the maximum number of line connections per particle
    limitConnections: true,
    maxConnections: 20,

    minDistance: 150,

    colorMode: 'rainbow',
    // Color of lines if colorMode: 'solid', must be hex color
    color: '#3FB568',
    // Transparency of particles
    transparency: 0.9,
    // 'square' or 'circle' shape of particles
    shape: 'square',
    // The exact number of particles to render
    count: 500,
    // The minimum particle size
    minSize: 10,
    // The maximum particle size

  cameraControls: {

    enabled: true,
    // Enable or disable smooth dampening of camera movement
    enableDamping: true,
    dampingFactor: 0.2,
    // Enable or disable zooming in/out of camera
    enableZoom: true,
    // Enable or disable constant rotation of camera around scene
    autoRotate: true,
    // Rotation speed -- higher is faster
    autoRotateSpeed: 0.3,
    // If true, camera position will be reset whenever any option changes (including this one)
    // Useful when turning off autoRotate, the camera will return to FOV where scene fits to canvas
    resetCameraFlag: false
  }
