## Integrate the component You are helping integrate a polished Meshh visual component into an existing React application. ### Component: Void Hole ### Category: Backgrounds ### Description A turbulent full-bleed WebGL vortex shader. ### Variant TypeScript + React + Tailwind CSS ### Dependencies - react - three - tailwindcss --- ### Usage Example ```tsx import VoidHole from "./VoidHole"; export default function Example() { return (

); } ``` ### Recreation Notes - Recreate the component as a self-contained React component using the source below as the implementation reference. - Preserve the visual behavior, shader/canvas setup, animation timing, interaction model, responsive sizing, and cleanup behavior. - The component must fill its parent container and should not rely on global body styles, fixed page positioning, or an external layout wrapper. - Keep designer-facing props stable and easy to connect to controls. - For WebGL, canvas, Three.js, OGL, GSAP, or pointer-driven effects, initialize browser-only APIs inside React effects and clean up animation frames, event listeners, renderers, textures, buffers, geometries, observers, and WebGL contexts on unmount. - Use the local image paths or replace them with project-hosted assets when adapting image-based effects. ### Full Component Source ```tsx import React, { useEffect, useRef } from "react";

); } ``` ### Integration Instructions 1. Install the listed dependencies. 2. Copy the component source into your project. 3. Import and render the component inside a parent with an explicit width and height. 4. Adjust props to match your design system, but preserve the cleanup and responsive canvas behavior. 5. If the component is decorative, keep it hidden from assistive technology or pair it with meaningful surrounding content.
