It can be used to simulate … WebJun 10, 2024 · Values in 3D perlin noise don't intrinsically mean anything on their own. Just as 2D perlin noise value doesn't "do" anything, you only choose to interpret that as a height value. One way to use 3D perlin noise underground could be that any value over some threshold (such as 0.8) would be considered "empty".
