To see the (small) examples, run make examples. Images will be generated in the ./example_images directory.

Run make.

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:
