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.
