This project was meant as a learning project for a simple terrain generation algorithm and as a project to practice writing Go code.
The project started with the implementation of the GUI using the Fyne library. Website.
The basic terrain generation is based around what is called "blobs" in the code. These are pieces of terrain that elevate the terrain in a zone, a bit like throwing earth balls at the ground.
Because just adding pieces of terrain randomly did not give good results, I added the concepts of "continents", wich allows the generation to put many blobs in a smallest zone.
The other problem I faced after adding continents is that the terrain was now visibly delimiting the zones. The way I tackled this problem is by adding a "distribution map" that would modify the way blobs are placed. Thus, when generating a new continent, some distribution centers are added, creating some kind of voronoi pattern. This greatly improved the results.
My next objective for this project was to place rivers on the map. In order to acheive that, I implemented shallow water simulation based on this paper. The simulation seems to work but the erosion did not give satisfactory results. I also tried using only the fluid simulation without erosion to place rivers but the results were not great either.
This project has been put on hold for the time being because I don't really have a solution for placing rivers. I might come back to it if I find something.
