Implementations

source

impl TrowbridgeReitzDistribution

source

pub fn new(alpha_x: Float, alpha_y: Float, sample_visible_area: bool) -> Self

source

pub fn roughness_to_alpha(roughness: Float) -> Float

Microfacet distribution function: In comparison to the Beckmann-Spizzichino model, Trowbridge-Reitz has higher tails - it falls off to zero more slowly for directions far from the surface normal.
