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
