Struct LightSource 

#[non_exhaustive]
pub struct LightSource {
    pub kind: LightKind,
    pub colour: [f32; 3],
    pub intensity: f32,
    pub importance: f32,
}

A single light source with colour and intensity.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

kind: LightKind

The type and geometric parameters of this light.

colour: [f32; 3]

RGB light colour in linear 0..1. Default [1.0, 1.0, 1.0].

intensity: f32

Intensity multiplier. Default 1.0.

importance: f32

Importance hint used by the renderer when more lights are pushed than fit under the per-frame cap. Higher values are kept; lower values are dropped first. Default 1.0.

The renderer ranks lights by importance * proximity_weight where proximity_weight scales the contribution of points and spots by distance to the active camera. Directional lights are treated as infinitely close (proximity_weight = 1).
