Module tray_rust::material::metal

Provides a material for modelling metal surfaces of varying roughness using the Torrance Sparrow BRDF and a Blinn microfacet distribution TODO: Add Ashikman-Shirley (spelling?) anisotropic microfacet model

Scene Usage Example

The metal material requires a refractive index and absorption coefficient that describe the physical properties of the metal along with a roughness to specify how rough the surface of the metal is.
