LWJGL Terrain in java

I'm really proud of this terrain I made using LWJGL and java. It works by generating a grid of points and changing the heights of those points with perlin noise. I also give each vertex a texture coordinate depending on the vertex's position. The real monster of this project was the element generation system, but luckily I was able to solve that by using similar indices of that of a square for each square formations the vertices made.

--EDIT--
I unfortunately lost the source code to the project, and so I can't provide it to anyone. If anyone wants to make something similar to this however, you can leave a comment and I might be able to help you.
