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:
