Struct Lighting

pub struct Lighting { /* private fields */ }

Implementations

impl Lighting

pub fn vertexnormalsepsilon(&mut self, vertexnormalsepsilon: f64) -> &mut Self

Epsilon for vertex normals calculation avoids math issues arising from degenerate geometry.

default: 0.000000000001

pub fn facenormalsepsilon(&mut self, facenormalsepsilon: f64) -> &mut Self

Epsilon for face normals calculation avoids math issues arising from degenerate geometry.

default: 0

pub fn ambient(&mut self, ambient: f64) -> &mut Self

Ambient light increases overall color visibility but can wash out the image.

default: 0.8

pub fn diffuse(&mut self, diffuse: f64) -> &mut Self

Represents the extent that incident rays are reflected in a range of angles.

default: 0.8

pub fn specular(&mut self, specular: f64) -> &mut Self

Represents the level that incident rays are reflected in a single direction, causing shine.

default: 0.05

pub fn roughness(&mut self, roughness: f64) -> &mut Self

Alters specular reflection; the rougher the surface, the wider and less contrasty the shine.

default: 0.5

pub fn fresnel(&mut self, fresnel: f64) -> &mut Self

Represents the reflectance as a dependency of the viewing angle; e.g. paper is reflective when viewing it from the edge of the paper (almost 90 degrees), causing shine.

default: 0.2

Trait Implementations

impl Default for Lighting

fn default() -> Lighting

Returns the “default value” for a type.

impl Serialize for Lighting

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
