🧩 Usage

"use client";
import { Canvas } from "@react-three/fiber";
import { GlitchVideo } from "@developer-hub/glitch-video-shader";

export default function MyScene() {
  return (
    <div className="h-screen w-screen bg-black">
      <Canvas orthographic camera={{ zoom: 200, position: [0, 0, 100] }}>
        <GlitchVideo
          videoSrc="/your-video.mp4"
          noiseTextureSrc="/noise-texture.jpg"
          width={6}
          height={4}
        />
      </Canvas>
    </div>
  );
}

⚙️ Props

Prop	Type	Default	Description
videoSrc	string	"/video3.mp4"	Path to the video file to be looped

📁 Asset Requirements

Video Files

• Place video files in your public/ folder
• Supported formats: .mp4, .webm, .mov
• Recommended: compressed, web-optimized videos for better performance

Noise Textures

• Grayscale images work best for displacement
• Formats: .jpg, .png, .webp
• Higher contrast = more dramatic glitch effects
• Recommended size: 512x512 or 1024x1024

🧠 How It Works

The component uses a sophisticated dual-shader approach:

Vertex Shader

• 3D Displacement: Creates surface bumps that follow mouse position
• Smooth Falloff: Uses smoothstep for natural height transitions
• Hover Animation: Animates displacement intensity based on interaction state

Fragment Shader

• RGB Channel Separation: Samples each color channel with slight offsets
• Noise-Based Displacement: Uses grayscale texture for organic distortion patterns
• Localized Effects: Glitch intensity is masked to areas near the cursor
• Real-time Updates: All effects respond to live mouse coordinates in UV space

Interaction System

• Smart Delays: 200ms delay before glitch activation prevents flickering
• Auto-timeout: Effects fade after 300ms of mouse inactivity
• Smooth Interpolation: Mouse position and hover states are smoothly animated
• UV Coordinate Mapping: Converts 3D mouse position to texture coordinates

🛠️ Advanced Usage

// Custom styling with Tailwind classes
<div className="relative overflow-hidden">
  <Canvas
    orthographic
    camera={{ zoom: 200, position: [0, 0, 100] }}
    className="absolute inset-0"
  >
    <GlitchVideo
      videoSrc="/hero-video.mp4"
      noiseTextureSrc="/custom-noise.jpg"
      width={8}
      height={6}
    />
  </Canvas>
  <div className="relative z-10 p-8">{/* Your overlay content */}</div>
</div>
