This is my python implementation of the Diamond Square algorithm to generate noisy pngs that tile seamlessly.
- different everytime
- noise tiles seamlessly
- always refits to use full color spectrum 0-255
- can represent terrain heightmap
- can represent biomes
- can represent caves
- looks like clouds if you remap colors from black-white to skyblue-white
- more fun can be had by applying a smooth step to all the pixels (can help for things like biomes, caves, & clouds)
Sorry for the lack of comments in the code, but I'm throwing this online for people who quickly need some tileable noise.
Made with python 3.6
Dependencies: PIL
You'll have PIL if you're working with Anaconda.
Just download this repository as a zip file, then run ImageDrawer.py. ds.png will appear in the directory where you ran it.
Be careful initializing DiamondSquare.Grid() higher than 9 if you muck with the code. If you try 10 for example, then the image width & height is (2^10)+1 and this will take 4 times longer than using 9.
Generation is single threaded on the cpu. I didn't really need this for real-time purposes. You'll have to wait a few seconds to get an image.
