module CrShader::Language::Std::Math

Overview

Standard Math & Geometry (require "std/math"):

Provides essential mathematical functions and utility curves:

• saturate(x): Clamps input to [0.0, 1.0].
• lerp(a, b, t): Linear interpolation alias.
• remap(val, in_min, in_max, out_min, out_max): Linear range remapping.
• rotate_2d(p, angle): Fast 2D vector rotation around origin.
• fresnel(power, normal, view): Power-law optical Fresnel reflection factor.
• rand(uv): 2D UV hashing pseudo-random generator.
