Implementations

impl Bxdf

pub fn matches_flags(&self, t: u8) -> bool

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

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

Sample the BxDF for the given outgoing direction, using the given pair of uniform samples.

The default implementation uses importance sampling by using a cosine-weighted distribution.

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

Evaluate the PDF for the given outgoing and incoming directions.

Note: this method needs to be consistent with Bxdf::sample_f().

pub fn get_type(&self) -> u8

Trait Implementations

impl Clone for Bxdf

fn clone(&self) -> Bxdf

Returns a copy of the value.

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

Performs copy-assignment from source.
