procedural-wallpapers

A collection of wallpaper generators. Forked from bagyoni. Rewritten in C++.

How to use (Linux only)

1. Install libmagick++-dev, base-devel and cmake
2. Clone this repository
3. Build the project by typing cmake . && make TARGET in the project root with TARGET being one of the algorithms found as .c file in src/
4. The compiled program outputs the image given as argument, or TARGET.png as default if no argument has been given.

Command-Line options

TARGET - Part of the Procedural Wallpaper Generator
Usage:
  TARGET [OPTION...]

  -s, --random-seed arg  Random Seed (default: <random>)
  -o, --out arg          Output file (default: TARGET.png)
  -H, --help             Print a command-line help text

 Image dimension options:
  -h, --height arg  Image Height (default: 1080)
  -w, --width arg   Image Width (default: 1920)

Generators

Clouds Perlin noise fed into a sigmoid function.	Fern Barnsley fern with mutation.
Flow Perlin flow field.	Islands Perlin noise fed into a cutoff function.
Landscape (original source) Simulated erosion using a midpoint displacement technique.	Lightning Similar to a Brownian tree but faster to generate.
Marrowlike (original source) If a pixel is too dark, give it a random brightness. Scale to double size. Repeat.	Mesh Transformations of the complex plane.
Tangles Rec-tangles.	Water Very simple interference pattern generator.
Wood Modular Perlin noise stretched along the x axis.	Zebra The same complex function as in the Mesh program, but from a different perspective.

Disclaimers

From the forked repository:

• The landscape generator is shamelessly stolen from here: https://tyrellrummage.github.io/landscape/
• The marrowlike generator follows the recursive algorithm described here: http://pcg.wikidot.com/forum/t-79282/multiplicative-cascades-ish
• The fern generator uses a fractal image compression method that might be patented (I couldn't find much information about it)
