Back in 2010 I wrote an article about the algorithms the original demo was in Flash. The generator intentionally makes unrealistic terrain that was designed for the needs of our game, Realm of the Mad God. You can right-click on the map to save a higher resolution image, or click the share link to save all the current parameters in a URL. Can you find an ice lake? They’re rare at the default temperature. Try clicking on the Seed input box and hold down the Up arrow key to quickly scan many different island shapes. The simplest way to explore the maps is to click the plus/minus arrows to change the Seed.
This map generator creates volcanic island style maps.
