Wildfire Spread Simulator!

Concept: This simulation models how fire spreads across a landscape based on fuel, wind, and ignition points. It demonstrates concepts like exponential growth (early spread), resource limitation (fuel burnout), and environmental influence (wind).

How to Use:

  1. View Controls: Use mouse or touch gestures (same as before: Orbit, Pan, Zoom) to look around the landscape.
  2. Set Ignition Points: Click or tap on the green ground surface to place initial fire starting points (blue sparks). You need at least one to begin.
  3. Adjust Parameters: Use the sliders below:
    • Spread Rate: Base chance for fire to spread to a nearby location each step.
    • Fuel Density: Represents how much flammable material is available. Higher density allows faster spread and potentially longer burning.
    • Sim Speed: How fast the simulation time progresses.
    • Wind Speed: How strongly the wind affects spread direction.
    • Wind Dir (°): The direction the wind is blowing from (0°=North, 90°=East, etc.). Fire spreads faster downwind.
    • Burnout Time: How many simulated seconds a location stays actively burning (orange/red) before turning into burnt ground (black).
  4. Run: Press 'Ignite!' to start the fire spread simulation.
  5. Control: Use 'Pause' to halt and examine the fire's progress, and 'Reset Sim' to clear the landscape and start over.

3D Wildfire Spread Simulation

Explore how ignition points, fuel, spread rate, wind, and burnout affect a browser-based 3D fire-spread model.

What this tool does

This interactive 3D wildfire simulation models fire spreading across a simple landscape. It is designed to make fire-growth concepts visible by showing ignited, actively burning, and burnt-out locations as the simulation runs.

Who this is for

How to use this tool

  1. Click or tap the green landscape to place one or more blue ignition points.
  2. Adjust spread rate, fuel density, simulation speed, wind speed, wind direction, and burnout time.
  3. Choose Ignite! to start the simulation, then use Pause to inspect it.
  4. Orbit, pan, or zoom the 3D view and choose Reset Sim to run another scenario.

Inputs

Inputs are the placement of ignition points on the landscape and the visible slider settings: spread rate, fuel density, simulation speed, wind speed, wind direction, and burnout time. The scene does not accept real terrain, weather, or fire-perimeter data.

Outputs

The output is a live 3D visualization with cyan ignition points, orange active fire, dark burnt-out locations, and an information display for burning count, burnt count, and simulation time. It does not produce a forecast, map, risk assessment, or emergency response recommendation.

Frequently asked questions

Is this a real wildfire forecast?

No. It is a simplified educational visualization with synthetic terrain and user-selected parameters, not a forecasting or emergency-management system.

What controls affect fire spread?

Spread rate and fuel density affect growth, while wind speed and direction influence where the simulation spreads. Simulation speed changes playback, and burnout time controls how long an active location burns.

Can I use real fire or weather data?

No. The current page accepts ignition clicks and its built-in sliders only; it does not import terrain, weather, or incident datasets.
