Reinventing Minecraft world generation
summary
A year and a half of rewriting world generation produces the Cave & Cliffs-era overhaul: chunked 16×16 generation uses Perlin noise octaves plus three named 2D fields—continentalness, erosion, peaks and valleys—mapped by splines to height and a squashing factor, while 3D noise yields density-based stone/air (positive → stone) and enables cheese and spaghetti caves plus aquifers; worlds remain procedural (one in 18 quintillion possible), run-time generation meets tight performance constraints, and the system ships and works in production.
