raisin::LocalFogVolume

struct · #include <rayrai/Weather.hpp>

Spherical local fog region evaluated in the post-process pass.

Values are sanitized by RayraiWindow::addLocalFogVolume() (ranges noted per field).

Public attributes

center

glm::vec3 center

World-space center, metres.

radius

float radius

Sphere radius, metres (>= 0.001).

color

glm::vec3 color

Linear RGB fog color (>= 0).

density

float density

Signed density. Positive values add local fog; negative values carve clearer regions from global/local fog in a bounded postprocess approximation. Clamped to [-1, 1].

edgeFade

float edgeFade

Fraction of the radius over which density fades out at the rim, [0.001, 0.99].

noiseScale

float noiseScale

Spatial frequency of the density noise, [0.001, 128].

noiseStrength

float noiseStrength

Noise modulation amount, [0, 1]; 0 = uniform density.
