Struct PointLight 

pub struct PointLight {
    pub position: Vec3,
    pub color: Vec3,
    pub intensity: f32,
    pub radius: f32,
}

Omnidirectional point light.

Fields

position: Vec3

color: Vec3

intensity: f32

radius: f32

Physical radius for energy-conserving area-light attenuation.

Implementations

impl PointLight

pub fn new(position: Vec3, color: Vec3, intensity: f32, radius: f32) -> Self

pub fn attenuation(&self, surface_pos: Vec3) -> f32

pub fn direction_to(&self, surface_pos: Vec3) -> Vec3

Direction from surface toward this light.

pub fn irradiance_at(&self, surface_pos: Vec3) -> Vec3

Irradiance at surface position.
