Required Methods

fn preprocess(
    &mut self,
    scene: &Scene,
    sampler: &mut Box<dyn Sampler + Send + Sync>
)

fn li(
    &self,
    ray: &mut Ray,
    scene: &Scene,
    sampler: &mut Box<dyn Sampler + Send + Sync>,
    depth: i32
) -> Spectrum

Returns the incident radiance at the origin of a given ray. Uses the scene's intersect routine to calculate a SurfaceInteraction and spawns rays if necessary.

fn get_pixel_bounds(&self) -> Bounds2i
