Procedural Planet Generation

A terrain synthesis engine that generates richly detailed world maps from pure noise — written entirely in Rust with zero external dependencies.

The generator implements hand-rolled value noise applied over two independent fields: height and moisture. Each point on the map is evaluated against both fields simultaneously, then resolved against a 9-biome classification table — producing varied, believable terrain that ranges from deep ocean trenches to snow-capped mountain ranges.

Output is rendered directly to PNG. The entire pipeline — noise generation, field sampling, biome classification, and image encoding — is authored from scratch, giving full algorithmic control over every parameter of the world.
