A hexagon based terrain simulator that relies on Perlin noise for the height values. You can use this tool freely to generate your own maps or upgrade the script to add new functionality.
If you're interested in running the code on your own, make sure to download Processing and use the Python module to run the .pyde file. Try playing with some of the variables at the top of the script to get a feel for how they affect the terrain generation.
Feel free to email me at firstname.lastname@example.org with 'Hex Map' in the subject if you have any questions.
All of these projects are available with the intention that other people will enjoy and learn from them.
