# Sphere Terrain

Terrain generation and erosion simulation on a sphere.

![Image of terrain](screenshot.png)

This project implements [this bachelor's thesis](https://www.firespark.de/resources/downloads/implementation%20of%20a%20methode%20for%20hydraulic%20erosion.pdf)

to work on a sphere's surface using the points of an IcoSphere as the nodes in place of a grid.

This project:

- Is based on [`hexasphere`](https://crates.io/crates/hexasphere).

- Features wetness and river simulations to construct biomes.

- Takes some liberties in implementing the thesis to make it work with a sphere. I am working on a document detailing the mathematics needed to adapt the algorithm to a sphere.

- Is parallelized by rayon using atomic instructions to simulate atomic floating point numbers.

- Is nightly only, since I use [Ralith's fast, ergonomic, and SIMD-enabled `clatter`](https://github.com/Ralith/clatter) for base terrain generation using simplex noise.

- Will be updated as I use it or as feature requests come in.

Documentation is light but mostly complete. I am always happy to discuss how to use the library, feel free to message me or open an issue asking questions.

The project featured in this video is a separate (currently) private project which I intend to develop into a game.

This library does _not_ do rendering, and mesh generation from the structures it provides is up to you.
