Azgaar's Fantasy Map Generator demo, v. 0.54b. This version is outdated. Please consider using an actual version located here. Sorry for the inconvenience, bl.ocks (Gist) is good for a small project, but it does not support folders and some other features, so I have to move the Demo to a GitHub pages.
Project goal is a procedurally generated map for my Medieval Dynasty simulator. Map should be interactive, scalable, fast and plausible. There should be enought space to place at least 500 manors within 7 regions. The imagined area is about 200.000 km2.
Click on the arrow to open the Options. Click on New map to genarate a random map based on options setup. Check out the project wiki for guidance. Development details are covered in my blog Fantasy Maps for fun and glory, development board is here. For bug reports and change requests please use the main project issues page.
