Struct LightProbe 

pub struct LightProbe {
    pub id: LightId,
    pub position: Vec3,
    pub radius: f32,
    pub sh_coeffs: [Vec3; 9],
    pub weight: f32,
    pub enabled: bool,
}

Pre-sampled spherical environment light at a world-space position.

Stores 9 spherical harmonic coefficients for fast ambient lighting.

Fields

id: LightId

position: Vec3

radius: f32

sh_coeffs: [Vec3; 9]

L0 + L1 + L2 spherical harmonic coefficients (9 Vec3 values).

weight: f32

enabled: bool

Implementations

impl LightProbe

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

pub fn evaluate_sh(&self, normal: Vec3) -> Vec3

Evaluate the probe’s ambient contribution for a given surface normal. Uses first-order SH approximation (L0 + L1 only: 4 coefficients).

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

Encode a uniform color as SH coefficients.

pub fn from_hemisphere( position: Vec3, radius: f32, sky: Vec3, ground: Vec3, ) -> Self

Set SH from a sky/ground hemisphere (fast approximation).

Trait Implementations

impl Clone for LightProbe

fn clone(&self) -> LightProbe

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for LightProbe

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
