Trait Implementations

impl Light for DiffuseAreaLight

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.
