Struct RayleighScattering 

pub struct RayleighScattering {
    pub beta: Vec3,
    pub scale_height: f32,
}

Rayleigh scattering parameters for Earth’s atmosphere.

beta — scattering coefficient per wavelength channel (m⁻¹). Default: (5.8e-6, 1.35e-5, 3.31e-5) for R, G, B. scale_height — characteristic scale height (m). Default: 8000 m.

Fields

beta: Vec3

scale_height: f32

Implementations

impl RayleighScattering

pub fn earth() -> Self

Earth-atmosphere defaults.

pub fn density(&self, h: f32) -> f32

Density relative to sea level at altitude h (metres).

pub fn beta_at(&self, h: f32) -> Vec3

Scattering coefficient at altitude h.
