Trait Implementations

impl Light for PointLight

fn sample_li(     &self,     iref: &InteractionCommon,     _u: &Point2f,     wi: &mut Vector3f,     pdf: &mut Float,     vis: &mut VisibilityTester ) -> Spectrum

Returns the radiance arriving at a point at a certain time due to the light, assuming there are no occluding objects between them.

fn power(&self) -> Spectrum

fn preprocess(&self, _scene: &Scene)

fn le(&self, _ray: &mut Ray) -> Spectrum

Default implementation returns no emitted radiance for a ray that escapes the scene bounds.

fn pdf_li(&self, _iref: &dyn Interaction, _wi: Vector3f) -> Float

fn sample_le(     &self,     u1: &Point2f,     _u2: &Point2f,     time: Float,     ray: &mut Ray,     n_light: &mut Normal3f,     pdf_pos: &mut Float,     pdf_dir: &mut Float ) -> Spectrum

fn get_flags(&self) -> u8

fn get_n_samples(&self) -> i32

fn pdf_le(     &self,     _ray: &Ray,     _n_light: &Normal3f,     pdf_pos: &mut Float,     pdf_dir: &mut Float )

impl Clone for PointLight

fn clone(&self) -> PointLight

Returns a copy of the value.

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

Performs copy-assignment from source.
