Trait Implementations

impl Copy for FresnelTBxdf

impl Clone for FresnelTBxdf

fn clone(&self) -> FresnelTBxdf

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for FresnelTBxdf

fn fmt(&self, __arg_0: &mut Formatter) -> Result

Formats the value using the given formatter.

impl Bxdf for FresnelTBxdf

fn kind(&self) -> BxdfType

returns the type of the bxdf

fn evaluate(&self, _wo: Vector3f, _wi: Vector3f) -> RGBSpectrumf

evaluate the function given two normalized directions

fn evaluate_sampled(
    &self,
    wo: Vector3f,
    _u: Point2f
) -> (RGBSpectrumf, Vector3f, Float, BxdfType)

Given an outgoing direction wo, and a uniform sample u from $[0,1)^2$, sample an incoming direction wi, and returns it with function value evaluated as f(wo, wi), as well as the pdf associated with the incoming direction, as well as the type of the scattering event.

fn pdf(&self, _wo: Vector3f, _wi: Vector3f) -> Float

evalute pdf given the incoming and outgoing direction

fn is(&self, t: BxdfType) -> bool

check if the type matches

fn evaluate_importance(&self, wo: Vector3f, wi: Vector3f) -> RGBSpectrumf

evaluate the function given two normalized directions, the particle being traced is camera-ray importance, rather than light radiance.

fn evaluate_importance_sampled(
    &self,
    wo: Vector3f,
    u: Point2f
) -> (RGBSpectrumf, Vector3f, Float, BxdfType)

Given an outgoing direction wo, and a uniform sample u from $[0,1)^2$, sample an incoming direction wi, and returns it with function value evaluated as f(wo, wi), as well as the pdf associated with the incoming direction， as well as the type of the scattering event. The particles being traced is camera-ray importance, rather tan light radiance

fn rho_hd(&self, wo: Vector3f, samples: &[Point2f]) -> RGBSpectrumf

hemispherical-directional reflectance

fn rho_hh(&self, samples0: &[Point2f], samples1: &[Point2f]) -> RGBSpectrumf

hemispherical-hemispherical reflactance
