Trait Implementations

impl Material for GlassMaterial

fn compute_scattering_functions(     &self,     si: &mut SurfaceInteraction,     mode: TransportMode,     allow_multiple_lobes: bool )

The method is given a SurfaceInteraction object that contains geometric properties at an intersection point on the surface of a shape and is responsible for determining the reflective properties at the point and initializing some member variables.

fn bump(d: &Arc<dyn Texture<Float> + Send + Sync>, si: &mut SurfaceInteraction) where     Self: Sized,

Computing the effect of bump mapping at the point being shaded given a particular displacement texture.
