Struct bevy::pbr::prelude::PointLight

pub struct PointLight {
    pub color: Color,
    pub intensity: f32,
    pub range: f32,
    pub radius: f32,
    pub shadows_enabled: bool,
    pub shadow_depth_bias: f32,
    pub shadow_normal_bias: f32,
}

A light that emits light in all directions from a central point.

Real-world values for intensity (luminous power in lumens) based on the electrical power consumption of the type of real-world light are:

Luminous Power (lumen) (i.e. the intensity member)	Incandescent non-halogen (Watts)	Incandescent halogen (Watts)	Compact fluorescent (Watts)	LED (Watts)
200	25		3-5	3
450	40	29	9-11	5-8
800	60		13-15	8-12
1100	75	53	18-20	10-16
1600	100	72	24-28	14-17
2400	150		30-52	24-30
3100	200		49-75	32
4000	300		75-100	40.5

Fields

color: Color

The color of this light source.

intensity: f32

Luminous power in lumens, representing the amount of light emitted by this source in all directions.

range: f32

Cut-off for the light’s area-of-effect. Fragments outside this range will not be affected by this light at all, so it’s important to tune this together with intensity to prevent hard lighting cut-offs.

radius: f32

Simulates a light source coming from a spherical volume with the given radius. Only affects the size of specular highlights created by this light. Because of this, large values may not produce the intended result – for example, light radius does not affect shadow softness or diffuse lighting.

shadows_enabled: bool

Whether this light casts shadows.

shadow_depth_bias: f32

A bias used when sampling shadow maps to avoid “shadow-acne”, or false shadow occlusions that happen as a result of shadow-map fragments not mapping 1:1 to screen-space fragments. Too high of a depth bias can lead to shadows detaching from their casters, or “peter-panning”. This bias can be tuned together with shadow_normal_bias to correct shadow artifacts for a given scene.

shadow_normal_bias: f32

A bias applied along the direction of the fragment’s surface normal. It is scaled to the shadow map’s texel size so that it can be small close to the camera and gets larger further away.
