Implementations

impl ProjectionLight

pub fn new( light_to_world: &Transform, medium_interface: &MediumInterface, i: &Spectrum, texname: String, fov: Float ) -> Self

pub fn new_hdr( light_to_world: &Transform, _medium_interface: &MediumInterface, i: &Spectrum, texname: String, fov: Float ) -> Self

pub fn projection(&self, w: &Vector3f) -> Spectrum

pub fn sample_li<'a, 'b>( &'b self, iref: &'a InteractionCommon, light_intr: &'b mut InteractionCommon, _u: Point2f, wi: &mut Vector3f, pdf: &mut Float, vis: &mut VisibilityTester<'a, 'b> ) -> Spectrum

pub fn power(&self) -> Spectrum

pub fn preprocess(&self, _scene: &Scene)

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

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

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

pub 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

pub fn get_flags(&self) -> u8

pub fn get_n_samples(&self) -> i32

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