Struct amethyst_renderer::PointLight

pub struct PointLight {
    pub center: [f32; 3],
    pub color: [f32; 4],
    pub intensity: f32,
    pub radius: f32,
    pub smoothness: f32,
}

A point light source.

Lighting calculations are based off of the Frostbite engine's lighting, which is explained in detail here in this presentation. The particular equation used for our calculations is Eq. 26, and the PointLight properties below map like so:

• I = intensity
• radius = radius
• n = smoothness

Fields

center: [f32; 3]

Coordinates of the light source in three dimensional space.

color: [f32; 4]

Color of the light.

intensity: f32

Brightness of the light source.

radius: f32

Maximum radius of the point light's affected area.

smoothness: f32

Smoothness of the light-to-dark transition from the center to the radius.
