🎬 Features

✨ Marvel Dusting Scene

• Layer-by-Layer Disintegration: Particles disintegrate from top to bottom in organized layers
• Realistic Particle Physics: 3D coordinate system with perspective projection
• Spiral Movement: Particles spiral toward the upper right corner with organic chaos
• Smooth Transitions: Fade-in and fade-out effects for seamless animations
• Touch Controls: Tap to toggle between disintegration and reassembly

🔄 Rotating Dusting Scene

• Animated Rotation: Particles rotate while maintaining disintegration effects
• Dynamic Transformations: Continuous rotation with particle system
• Smooth Scene Transitions: Elegant cross-fade between scenes
• Interactive Experience: Responsive touch controls

🚀 Quick Start

Prerequisites

• iOS 26.0+
• Xcode 26.0+
• Swift 6.0+

Installation

1. Clone the repository

   git clone https://github.com/yourusername/DustingSceneKitApp.git
   cd DustingSceneKitApp

2. Open in Xcode

   open DustingSceneKitApp.xcodeproj

3. Configure the project

   • Select your development team
   • Set bundle identifier
   • Connect your iOS device or use simulator

4. Build and Run

   • Press Cmd + R to build and run on your device/simulator

🎮 Usage

Basic Interaction

• Single Tap: Start disintegration effect
• Second Tap: Reverse effect and reassemble particles
• Next Button: Transition to rotating dusting scene
• Back Button: Return to main marvel dusting scene

Customization

The app is highly customizable through several parameters:

// Particle System Configuration
private let totalLayers: Int = 16        // Number of disintegration layers
private let layerDelay = 0.1             // Delay between layer activation
let spiralStrength: CGFloat = 2.0        // Spiral effect intensity
let chaosStrength: CGFloat = 1.5         // Random movement intensity
