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.
Currently supports cave-like noise generation via the CLI cave subcommand,
with six different cave types to choose from.
To see the (small) examples, run make examples. Images will be generated in
the ./example_images directory.
Run make.
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
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:
