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.
