functions.hpp File Reference

Defines modular function objects for procedural generation, including noise algorithms (Perlin, Simplex, Worley), geometric primitives (disks, waves, slopes), and fractal compositions (FBM, IQ, Swiss). Provides parameter control for frequency, seeding, and layer blending to construct complex procedural patterns. More...
