LinesBackground

The LinesBackground component is a React component that renders a 3D lines background using Three.js and React Three Fiber. It creates a canvas that fills the viewport and draws randomly positioned lines in 3D space.

Usage

import LinesBackground from '@site/src/components/LinesBackground';

const MyComponent = () => {
  return (
    <div>
      <LinesBackground />
      {/* Your other components */}
    </div>
  );
};

Component Structure

• LinesBackground: This functional component is responsible for creating and managing the Three.js line object. It uses useEffect to initialize the geometry and material for the lines when the component mounts.
• LinesCanvas: This component wraps LinesBackground with a Canvas component from @react-three/fiber. It sets up the Three.js canvas and places the LinesBackground within it.

Styling

The LinesCanvas component applies inline styles to make the canvas take up the full viewport and position it behind other content:

<Canvas style={{ position: 'absolute', top: 0, left: 0, zIndex: 0, width: '100%', height: '100%' }}>

• position: 'absolute': Positions the canvas absolutely relative to its nearest positioned ancestor.
• top: 0, left: 0: Anchors the canvas to the top-left corner of its parent.
• zIndex: 0: Ensures the canvas is rendered behind other content.
• width: '100%', height: '100%': Makes the canvas fill the entire viewport.

Dependencies

• @react-three/fiber: Used for rendering Three.js scenes in React.
• three: The core Three.js library.

Example

import React from 'react';
import LinesBackground from '@site/src/components/LinesBackground';

function Example() {
  return (
    <div style={{ position: 'relative', height: '300px' }}>
      <LinesBackground />
      <div style={{ position: 'relative', zIndex: 1, color: 'white' }}>
        {/* Content that will appear in front of the lines background */}
        <h1>Welcome</h1>
        <p>This is an example of using LinesBackground component.</p>
      </div>
    </div>
  );
