A version of mapgen4 that animates the generation (but no longer allows painting). Just for fun. Caveat: I’m taking 2D slices of 3D noise, but Wavelet Noise[1] by Cook and DeRose says:
When rendering, it is common to texture 2D surfaces by sampling a 3D noise function, but the resulting 2D texture will in general not be band-limited, even if the 3D function is perfectly band-limited.
This is something I didn’t know until I saw the paper in 2024 Sep, and it’s something I might need to look at further.
