Struct ScatteringTerm 

pub struct ScatteringTerm {
    pub absorption: Vec3,
    pub scattering: Vec3,
    pub falloff: Falloff,
    pub phase: PhaseFunction,
}

An individual element of a ScatteringMedium.

A ScatteringMedium can be built out of a number of simpler ScatteringTerms, which correspond to an individual element of the medium. For example, Earth’s atmosphere would be (roughly) composed of two ScatteringTerms: the atmospheric gases themselves, which extend to the edge of space, and suspended dust particles, which are denser but lie closer to the ground.

Fields

absorption: Vec3

This term’s optical absorption density, or how much light of each wavelength it absorbs per meter.

units: m^-1

scattering: Vec3

This term’s optical scattering density, or how much light of each wavelength it scatters per meter.

units: m^-1

falloff: Falloff

This term’s falloff distribution. See the docs on Falloff for more info.

phase: PhaseFunction

This term’s phase function, which determines the character of how it scatters light. See the docs on PhaseFunction for more info.

Trait Implementations

impl Clone for ScatteringTerm

fn clone(&self) -> ScatteringTerm

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Default for ScatteringTerm

fn default() -> ScatteringTerm

Returns the “default value” for a type.
