Implementations

impl Light

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

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