Struct tray_rust::bxdf::specular_reflection::SpecularReflection

pub struct SpecularReflection<'a> { /* fields omitted */ }

Specular reflection BRDF that implements a specularly reflective material model

Methods

impl<'a> SpecularReflection<'a>

pub fn new(c: &Colorf, fresnel: &'a dyn Fresnel) -> SpecularReflection<'a>

Create a specularly reflective BRDF with the reflective color and Fresnel term

Trait Implementations

impl<'a> BxDF for SpecularReflection<'a>

fn bxdf_type(&self) -> EnumSet<BxDFType>

Get the type of this BxDF

fn eval(&self, _: &Vector, _: &Vector) -> Colorf

We'll never exactly hit the specular reflection direction with some pair so this just returns black. Use sample instead

fn sample(&self, w_o: &Vector, _: &(f32, f32)) -> (Colorf, Vector, f32)

Sampling the specular BRDF just returns the specular reflection direction for the light leaving along w_o

fn matches(&self, flags: EnumSet<BxDFType>) -> bool

Check if this BxDF matches the type flags passed

fn pdf(&self, w_o: &Vector, w_i: &Vector) -> f32

Compute the pdf of sampling the pair of directions passed for this BxDF

impl<'a> Clone for SpecularReflection<'a>

fn clone(&self) -> SpecularReflection<'a>

Returns a copy of the value.

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

Performs copy-assignment from source.
