procedural-clouds
by CK42BB
Generate beautiful procedural clouds in Three.js using WebGPU raymarching with WebGL2 billboard/mesh fallbacks. Covers all 10 major cloud genera (cumulus, stratus, cirrus, cumulonimbus, stratocumulus, altocumulus, altostratus, nimbostratus, cirrostratus, cirrocumulus) with physically-inspired lighting including silver linings, god rays, sunset coloring, and Mie/Rayleigh scattering approximation. Provides volumetric raymarching, billboard impostor, and mesh-cluster rendering paths with animated drift, morphing, and dynamic formation/dissipation. Use when building skies, cloudscapes, weather systems, flight scenes, atmospheric backgrounds, or any scene requiring clouds. Triggers: "procedural clouds", "cloud rendering", "volumetric clouds", "skybox clouds", "cloudscape", "cumulus", "cirrus", "storm clouds", "cloud shader", "cloud billboard", "raymarched clouds", "cloud lighting", "god rays", "sky rendering".
