This project is a way to explore different rules and colors for life-like cellular automata. The parameters can be changed via the interface on the top right corner. Here is a compilation of some interesting automata I found with the tool - https://www.youtube.com/watch?v=ICpImf7Y3pc
A cellular automaton is Life-like (in the sense of being similar to Conway's Game of Life) if it meets the following criteria:
- The array of cells of the automaton has two dimensions.
- Each cell of the automaton has two states (conventionally referred to as "alive" and "dead", or alternatively "on" and "off")
- The neighborhood of each cell is the Moore neighborhood; it consists of the eight adjacent cells to the one under consideration and (possibly) the cell itself.
- In each time step of the automaton, the new state of a cell can be expressed as a function of the number of adjacent cells that are in the alive state and of the cell's own state.
Conway's Game of Life is a specific example of a life-like cellular automaton.
The rules are written as a string where each of characters is a sequence of distinct digits from 0 to 8.
The presence of a digit d in the 'birth' parameter means that a dead cell with d live neighbors becomes alive in the next generation of the pattern and the presence of d in the 'survival' parameter means that a live cell with d live neighbors survives into the next generation.
Clicking on 'random' will create randomized rules.
The color of a living cell is determined by the number of living neighbours it has.
Clicking on 'random' will select random colors, while clicking on 'black & white' will set the color of a living cell to white regardless of the number of living neighbours it has.
R - Toggle 'random start'.
B - Randomize rules.
C - Randomize colors.
Space - Set & go.
This implementation is using the
CanvasRenderingContext2D interface. I am initializing a data array and using it as data for an image. Each generation I iterate over the differences from the previous generation and fill the colors according to the new state. For more information see the
