Cellular Automata Terrain

Python program that runs a cellular automata simulation on a 2D grid and exports the result as an animated HTML visualization.

---

FILES

automata.py

• Runs the simulation
• Defines tile types and rules
• Prints the grid in the terminal
• Controls timestep delay
• Exports frames to HTML

export_html.py

• Takes simulation frames
• Generates an HTML file with a colored grid animation

---

REQUIREMENTS

• Python 3.x
• Web browser (to open the exported HTML file)

No external libraries are required.

---

USAGE

Run with default settings:

python automata.py

Run with custom parameters:

python automata.py <rows> <cols> <steps> <delay> <seed>

Example:

python automata.py 30 80 400 0.1 42

Arguments:

• rows : grid height
• cols : grid width
• steps : number of simulation steps
• delay : time between steps in seconds
• seed : random seed (optional)

---

OUTPUT

• Terminal output: ASCII grid updated every timestep
• File output: automata.html

Open automata.html in a browser to view the animated grid.

TILES

Symbol Meaning

' ' Empty '#' Wall 'T' Tree '~' Water '.' Grass '^' Mountain

Tile behavior is defined in automata.py.

NOTES

• All simulation updates are synchronous
• HTML export does not affect simulation logic
• Changing tile colors only requires editing export_html.py
