Fungal Life Simulation

This project simulates fungal growth using a grid-based visualization and generates an animated GIF of the simulation.

Project Files

  • fungalLife.js: The main JavaScript file that contains the code for the fungal growth simulation.

Setup Instructions

  1. Install Dependencies: Ensure you have Node.js installed. Then, install the required npm packages:

    npm install canvas gifencoder

  2. Run the Simulation: Execute the following command to run the simulation and generate the GIF:

    node fungalLife.js

Code Overview

Grid and Cell States

  • The simulation uses a 200x200 grid.
  • Each cell can be in one of the following states:
    • EMPTY: Represented by 0.
    • HYPHAE: Represented by 1.
    • TIP: Represented by 2.
    • SPORE: Represented by 3.

Initial State

  • The grid is initialized with one spore placed at the center of the grid.

Update Rules

  • Spores can turn into tips with a probability of 0.1.
  • Tips grow into hyphae and can create new tips in one of the eight possible directions (including diagonals).
  • Hyphae can randomly turn into spores with a probability of 0.01.

Visualization

  • The grid is visualized using the canvas library.
  • Different cell states are represented by different colors:
    • EMPTY: White
    • HYPHAE: Green
    • TIP: Dark Green
    • SPORE: Brown

GIF Creation

  • The simulation is captured and saved as an animated GIF using the gifencoder library.
  • The GIF is created with a delay of 100 ms between frames and a quality setting of 10.

Main Simulation Loop

  • The simulate function runs the simulation for 1000 iterations and generates the GIF.

Output

  • The output GIF file will be saved as fungal-life.gif in the project directory.

Example Command

To run the simulation, use:

node fungalLife.js

Notes

  • Modify the grid size, cell size, and probabilities in the code as needed for different simulation behaviors.
  • Ensure the required libraries are installed before running the script.
