# Terrain-Generation-Study
Using Perlin noise to generate a map texture and then generate an LOD enabled terrain mesh from the map.
## About:
This was going to be my attempt at creating a No Man's Sky-esque planet/terrain system. The planet would share the same map as the terrain and when a ship would land, the appropriate terrain chunks would be generated. I however lost steam after implementing the terrain chunk LOD system and never got around to the UV, transform, and spherical coordinate system translating. If I create a similar project in the future I will use this as the basis.
## Features:
* Implements a port of LibNoise for C# for noise generation
* Octahedron sphere procedural generation
* Color mapping based off of noise map values
* Terrain chunk generation based off of noise map
* Circular buffer implementation to allow terrain chunk wrapping
* Terrain chunk LOD system for better performance
* Threading for map generation
## Planned, but Never Implemented:
* Fix seams between terrain chunks
* UV, transform, and spherical coordinate translation
* Landing on planet generates appropriate terrain chunks
* Planet rotation
* Planetary generation from seed
* Longitude/Latitude system
