Struct AreaLight 

pub struct AreaLight {
    pub position: Vec3,
    pub direction: Vec3,
    pub up: Vec3,
    pub color: Color,
    pub intensity: f32,
    pub shape: AreaShape,
    pub enabled: bool,
    pub two_sided: bool,
    pub radius: f32,
}

An area light that emits from a shaped surface. Uses an approximated most-representative-point (MRP) technique for irradiance.

Fields

position: Vec3

direction: Vec3

up: Vec3

color: Color

intensity: f32

shape: AreaShape

enabled: bool

two_sided: bool

radius: f32

Attenuation radius — area light contribution fades to zero here.

Implementations

impl AreaLight

pub fn new_rectangle( position: Vec3, direction: Vec3, width: f32, height: f32, color: Color, intensity: f32, ) -> Self

pub fn new_disc( position: Vec3, direction: Vec3, radius: f32, color: Color, intensity: f32, ) -> Self

pub fn rect_corners(&self) -> [Vec3; 4]

Compute the four corners of a rectangular area light in world space.

pub fn irradiance_at(&self, point: Vec3, normal: Vec3) -> Color

Approximate irradiance at a point using the most-representative-point method.
