Hello there!
This Repository is full of my little java-projects. Have fun looking around! :D
Here is an Overview:

• Diamond-Square Algorithm (Terrain Mesh Generation)

Diamond-Square Algorithm ↗

The Diamond-Square Algorithm presents a very simple technique for generating natural-ish looking terrain.

How it works:

You start with four vertices arranged as a square and assign each one a random height. Then comes the Diamond Step, during which you compute the average of the four corners and add a center vertex with a height equal to that average ± a random offset (the "variance"). During the follow-up Square Step, vertices are inserted at the edge of the square similar to the Diamond Step, such that a square grid is restored. If you repeat this process recursively a sufficient number of times reducing the variance as you go, you get natural terrain looking something like this:

How to color it:

Naturally though, the programm only produces an .obj-file, which can be viewed with any 3d viewer of your choice. To make it more realistic and colorful, I used ShaderLabWeb, a web shader that's more or less intuitive to use. There, you just need to upload the .obj-file and can then test your shader-writing Skills :).
