When opening the above URL and scrolling through the page, a white space appears. Here we create a non-uniform grid that is the base of natural terrain that is artificial and not chaotic.


Click "Generate random points" to create a grid. Then, multiple black dots are randomly displayed in space. Each time you click "Generate random points", the position of the black dot changes.


After creating the grid scroll down again to the place where there is a blue mesh map. Here we set the height to decide the height of the terrain.


When you click "Add random slope", the map is colored yellow and blue, purple, and a black line is displayed. Yellow shows high place, purple shows low place, black line is coastline. In other words, the yellow part becomes the land, and the purple part becomes the sea.


When you click "Add cone", the coastline turns towards the land centering on the center of the map according to the number of clicks.


On the other hand, if you click "Add inverted cone" the coastline will turn around the coast line towards the sea.


After deciding the shape of the coastline, click "Add five blobs" this time. This has the role of raising the terrain on the circle, the topography near the coastline became dense.


Every time you click "Add five blobs", the excitement increases, but the position to be raised is random.


Scroll the page again and click "Copy height map from above" and copy the created map to the white space.


Now click "Erode" to give the coastline erosion by water. It is natural that the coastline is eroded by water and rattled so that the coastline on the general map is not straight.


Once erosion is granted scroll again and click "Copy heightmap from above" to copy the map.


Here you can check the terrain of the map you created. By clicking "Show / Hide coastline" you can switch coastline display on / off.


Click Show / Hide rivers to turn river display on or off.


If you click "Show / Hide slope shading" you can check the shadow due to height difference.


After checking the terrain, scroll the page again and click "Copy heightmap from above".


Click "Add new city" to add a town to display on the map.


To add a lot of town, click multiple times is OK.


After adding the town, scroll the page again and click "Copy map from above", the map of the Fundasy world was displayed based on the information created. The name of the town I added is completely random, but it is finished in the feeling that it seems to be in the novel.
