Struct LightingUniforms 

pub struct LightingUniforms { /* private fields */ }

Bundles of uniforms supplied to lighting and shading routines.

Implementations

impl LightingUniforms

Implements LightingUniforms builders and the LightingUniforms::shade entry point used by the ray tracer.

pub fn with_eye(eye: Vector3D) -> LightingUniforms

Creates a uniform set with an empty light list, default ambient, and the supplied eye position.

Arguments

• Vector3D - The view position used for specular calculations.

Returns

• LightingUniforms - The new uniform set.

pub fn add_light(&mut self, light: Light)

Adds a light to the uniform set.

Arguments

• Light - The light to append.

pub fn shade( &self, position: Vector3D, normal: Vector3D, material: &Material, occluders: &[(Vector3D, f64)], ) -> Vector3D

Shades a surface point by summing ambient, per-light Lambertian, and per-light Phong contributions, gated by a soft shadow factor.

Arguments

• Vector3D - The world-space position of the shaded point.
• Vector3D - The surface normal (unit length).
• &Material - The material at the shaded point.
• &[(Vector3D, f64)] - (center, radius) occluder tuples used by soft_shadow_factor.

Returns

• Vector3D - The final shaded color.
