Material defines the interface that material implementations must provide.

Required Methods

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.

Provided Methods

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.
