• Real-time N-body gravitational simulation
• Customizable initial conditions (mass,radius, position, velocity)
• Interactive camera controls (zoom, pan, rotate)
• Orbital trails and forecast

• react-three/drei for 3D rendering
• Jotai for state management
• Tailwind CSS for styling

1. Clone the repo:

   git clone https://github.com/jpbhatt21/planetarium3d.git
   cd planetarium3d

2. Install dependencies:

   npm install

npm run dev

Use the GUI to set simulation parameters, then press Space to launch the simulation.

Edit Universal Variables to adjust:

• Time Step: simulation delta-t
• Gravitational Constant: simulation G
• Elastic Constant: simulation k
• Forecast Limit : number of steps to forecast
• Trail Limit: number of steps to show in the trail
• Anchor : anchor body for the camera
• Background: background texture for skybox
• Texture Quality: quality of the background texture
• Ambient Light & Intensity : ambient light settings
• Bloom & Intensity : bloom settings

Export & Import simulation settings via JSON files.

• Solar System Demo: Preloaded Sun, Earth, Mars, Jupiter
• Custom Scenarios: Create your own scenarios by adding celestial bodies with custom mass, radius, position, and velocity.
