The program for visualizing a probabilistic cellular automata
The original idea was found here, and the author is this person.
Let a square be surrounded on each side by a new square of the same size with a chance of q. Newly formed squares reproduce other squares and so on, to infinity. We will limit the growth of the population by setting a certain maximum allowable number of squares, upon reaching which the program will be completed.
As you probably noticed when looking at the images below, the edges of the shapes have a different color, into which the initial color smoothly flows. This was done not only to illustrate the process of structure development, but also for greater saturation and prettiness of images.
Install/upgrade required packages with pip install -r requirements.txt --upgrade.
- Check out all the command-line parameters below.
- Then you can specify the colors and allowed reproduction directions in the
config.json. - Run the
renderer.pywithpython src/renderer.py [parameters you need].
usage: renderer.py [-h] [-sp Y X] [-p FLOAT] [-mc INT] [-minp FLOAT] [-maxp FLOAT] [-rc] [-rbg] [-cn INT] [-s INT] [-o] [-fi] [-t] [-si] [-pi PATH] [-dsi] [-sv]
[-pv PATH] [-vfps INT] [-vs INT] [-sg] [-pg PATH] [-gd INT]
width height
options:
-h, --help show this help message and exit
Required options:
width The width of the image.
height The height of the image.
Basic options:
-sp Y X, --start-point Y X
The coordinate of a starting point. Default value: middle of the image.
-p FLOAT, --probability FLOAT
The probability that a square will multiply in a one direction. Default value: 0.51
-mc INT, --max-count INT
The maximum number of squares in the image. Default value: (width * height) // 2.
-minp FLOAT, --min-percent FLOAT
The program will work until the nebula is filled with a chosen or greater percentage.
-maxp FLOAT, --max-percent FLOAT
The program will work until the nebula is filled with a chosen percentage.
Coloring options:
-rc, --random-colors All colors will be chosen randomly.
-rbg, --random-background
The background color will be chosen randomly.
-cn INT, --colors-number INT
The number of colors to use in the image. Default value: 3. Use with: -rc.
Additional options:
-s INT, --seed INT The program will generate the nebula based on the entered seed. In this case, the generation time is significantly increased.
-o, --opaque All colors will be opaque including background.
-fi, --fade-in Starting color is white. The color of each new generation will fade into the specified color. Use with: -rc -cn 1
-t, --torus The nebula will develop on a grid with toroidal topology.
Image options:
-si, --save-image The rendered image will be saved.
-pi PATH, --path-image PATH
The path where the image will be saved. Default path: output/
-dsi, --dont-show-image
Do not show image in the end.
Video options:
-sv, --save-video The rendered video will be saved.
-pv PATH, --path-video PATH
The path where the video will be saved. Default path: output/
-vfps INT, --video-fps INT
The frame rate of the video. Default value: 60.
-vs INT, --video-size INT
The size of the video in MB to which the size of the original video will be reduced using compression.
GIF options:
-sg, --save-gif The rendered GIF will be saved.
-pg PATH, --path-gif PATH
The path where the GIF will be saved. Default path: output/
-gd INT, --gif-duration INT
The display duration of each frame of the GIF in milliseconds. Default value: 30.The original idea was found here, and the author is this person.
