module CrShader::Language::Std::Noise

Overview

Procedural Noise & Hashes (require "std/noise"):

Procedural noise routines requiring zero texture fetches:

• hash11(p) .. hash33(p): Jarzynski & Olano hash functions for procedural seeds.
• value_noise(p): Smooth 2D value noise.
• voronoi(p): Cellular Voronoi distance calculation.
• simplex_noise_2d(p): 2D simplex noise gradient.
• fbm(p, octaves): Multi-octave Fractal Brownian Motion for clouds, terrain, and smoke.
