3D Tesla Coil Simulator

A 3D interactive Tesla coil simulator built using Three.js with configurable electrical arc effects.

Simulation in Day Mode

Simulation in Night Mode

Features

• Realistic 3D model of a Tesla coil (primary coil, secondary coil, and toroid)
• Dynamic electrical arc simulation with physics-based behavior
• Interactive GUI controls for:
  • Intensity (affects arc length and frequency)
  • Arc color
  • Number of simultaneous arcs
  • Sound effects (on/off)
  • Day/Night mode to control panel
  • Advanced arc physics
• Smooth camera controls (orbit, zoom)
• Responsive design that adapts to window size

How to Run

1. Make sure you have Python 3 installed
2. Clone this repository
3. Navigate to the project directory
4. Run the local server:

   python3 -m http.server 8000

5. Open http://localhost:8000 in your browser

Controls

• Left-click + drag: Rotate view
• Right-click + drag: Pan view
• Scroll wheel: Zoom in/out
• GUI panel (top-right): Adjust simulation parameters

Technical Details

• Built with Three.js r163
• Uses dat.GUI for parameter controls
• Arc simulation uses:
  • Randomized path generation
  • Time-based lifecycle management
  • Proper resource cleanup
• Responsive design using window resize events

Future Enhancements

• Implement more advanced arc physics
• Add ground plane and spark effects
• Support for mobile/touch controls
