Some implementations of procedural generation algorithms : Marching squares, Perlin worm, Chunk divided world generation, etc. More features to come : modularity of terrain generation, terrain painting, world division into chunks, vegetation and poi generation, maybe biomes ?
This is a preety straighforward implementation of the algorithm. The world is divided into tiles. On each tile a 3D model is instanciated based on the result of the marched tile. These models have been created in Blender and separated in 3 parts : bottom, middle and top. This way we can control the height of the terrain just by modifying the y scale of the middle part of the tile.
River generation based on perlin worms :
This river has been generated using two sets of parameters, held by scriptable objects :
- River noise settings which are FastNoise settings (see https://github.com/Syomus/ProceduralToolkit/tree/master/Runtime/FastNoiseLib)
- Perlin worm settings which controls the worm settings : length, convergeance, creation speed (for demo purposes)
The generation is not always perfect as it can be shown on the picture : the river sometimes crosses itself, for the moment it is not a big deal, we can imagine lake being created on these intersection points.
