Implementations

impl MicrofacetTransmission

pub fn new( t: Spectrum, distribution: MicrofacetDistribution, eta_a: Float, eta_b: Float, mode: TransportMode, sc_opt: Option<Spectrum> ) -> Self

pub fn f(&self, wo: &Vector3f, wi: &Vector3f) -> Spectrum

pub fn get_type(&self) -> u8

pub fn sample_f( &self, wo: &Vector3f, wi: &mut Vector3f, u: &Point2f, pdf: &mut Float, _sampled_type: &mut u8 ) -> Spectrum

Override sample_f() to use a better importance sampling method than weighted cosine based on the microface distribution

pub fn pdf(&self, wo: &Vector3f, wi: &Vector3f) -> Float
