# Terra: Worlds from noise

> Gradient (Perlin) noise with a quintic fade, summed over fractal octaves (fBm) into terrain coloured by height. 7 tests, including that noise is exactly zero at every integer lattice point.

Terra is a procedural terrain generator that turns layered noise into coloured landscapes you can tweak in real time. The signature technique is gradient (Perlin) noise with a quintic fade curve summed over fractal octaves (fBm), then mapped to colour by height, with a test confirming the noise is exactly zero at every integer lattice point. It is a from-scratch, dependency-light build you can download and run locally.
