Struct LightBaker 

pub struct LightBaker {
    pub sample_count: u32,
    pub hemisphere_samples: Vec<Vec3>,
}

CPU-side light baking utility.

Casts shadow rays and computes irradiance at sample points, storing results in a LightMap for static illumination.

Fields

sample_count: u32

hemisphere_samples: Vec<Vec3>

Implementations

impl LightBaker

pub fn new(sample_count: u32) -> Self

pub fn bake_point_ibl( &self, position: Vec3, normal: Vec3, env: &IblEnvironment, ) -> Vec3

Bake indirect irradiance at a sample point from the sky environment.

pub fn bake_point_direct( &self, position: Vec3, normal: Vec3, manager: &LightManager, ) -> Vec3

Bake direct irradiance from all active lights (no shadow ray casting).

pub fn bake_samples( &self, samples: &[(Vec3, Vec3)], manager: &LightManager, env: &IblEnvironment, ) -> Vec<Vec3>

Full bake: direct + IBL for a set of sample points.

pub fn bake_plane( &self, width: u32, height: u32, origin: Vec3, u_axis: Vec3, v_axis: Vec3, normal: Vec3, manager: &LightManager, env: &IblEnvironment, ) -> LightMap

Bake a 2D lightmap for a planar surface.
