So over the past little bit I’ve been experimenting with different procedural generated terrains and have run into a few issues. So basically, biomes in this case will refer to terrain that has different colors and its own unique height map. At first I used noise to select the biomes but ran into the issue as the world looks super repetitive and lame. Basically if you declare which biome should spawn at which noise level ex (Plains = .2, Arctic = .5, Lava = 1) then every biome will be surrounded with the center biome as noise incrementally increases from one to another.
The fix was to do what Minecraft does and give the world a moisture level and a temperature and decide the biomes based on this. That way the biomes give much seemingly random generation. However the issue becomes that the height maps do not blend well, and given that 2 different numbers decide which biome is picked, its super hard to blend them.
A solution is reading through multiple positions on the map and making sort of “averages” between 2 different points. Given that theres about 3600 blocks I’d like to not iterate through all that extra data.
What I was trying earlier is instead of assigning each point a biome, assign every point a mixture of surrounding biomes. So if the point is on the cusp of being another biome, assign it to the average of those height maps. The issue I had with this is it was extremely hard to implement with the biomes being a 2d table.
There can be slight issues when 4 biomes collide as seen in the green section, but honestly its okay.
