Enum FogFalloff 

pub enum FogFalloff {
    Exponential {
        density: f32,
    },
    Linear {
        start: f32,
        end: f32,
    },
    ExponentialHeightSlab {
        density: f32,
        bottom: f32,
        top: f32,
    },
}

How much of a surface’s light the fog replaces, by its distance d from the camera in metres.

Variants

Exponential

1 - exp(-density * d); density per metre.

Fields

density: f32

Linear

0 up to start, 1 from end, linear between; metres, start < end.

Fields

start: f32

end: f32

ExponentialHeightSlab

Uniform density inside a horizontal slab, zero outside it. bottom and top are absolute world Y heights in metres (bottom < top), in core’s Y-up frame. Replace by 1 - exp(-density * inside) where inside is the length in metres of the camera-to-surface segment inside that slab; density is per metre. This is extinction and a constant fog colour, not a height-dependent density gradient or anisotropic scattering.

Fields

density: f32

bottom: f32

top: f32
