Trait Implementations

impl<'a> BxDF for TorranceSparrow<'a>

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

Get the type of this BxDF

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

Evaluate the BxDF for the pair of incident and outgoing light directions, w_i and w_o.

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

Sample an incident light direction for an outgoing light direction w_o. samples will be used to randomly sample a direction for the outgoing light Returns the color of the material for the pair of directions, the incident light direction and pdf

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

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

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

Check if this BxDF matches the type flags passed

impl<'a> Clone for TorranceSparrow<'a>

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

Returns a copy of the value.

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

Performs copy-assignment from source.
