noise
Noise-generation for use in hexagram30 projects
Based on the noise-rs project. Implements two custom noise
modifiers used for cave generation: threshold and invert.
Features
Currently supports cave-like noise generation via the CLI cave subcommand,
with six different cave types to choose from.
Examples
To see the (small) examples, run make examples. Images will be generated in
the ./example_images directory.
Building
Run make.
Usage
After building, run the following for detailed option and flag info:
./bin/hxgm30-noise help./bin/hxgm30-noise -h./bin/hxgm30-noise cave -h
The following will generate a test.png image in the ./example_images directory:
./bin/hxgm30-noise -s 2 -r 800,800 -t -0.2 -o test.png cave complex
Example Output
Here's a thumnail of six different cave systems generated with this tool (click to see large image):
Here's one of them generated with the ASCII output option:
And here's another one colored for land and sea:
Here's one generated with more than two levels (and colors), useful for things like land cover:
