Struct LightClusters 

pub struct LightClusters {
    pub cells: Vec<u32>,
    pub dims: [u32; 3],
}

One frame’s clustered light assignment, in storage the caller reuses.

Fields

cells: Vec<u32>

The cell records, dims.x * dims.y * dims.z * CELL_WORDS long.

dims: [u32; 3]

The grid the records were written for.

Implementations

impl LightClusters

pub fn update( &mut self, cfg: &ClusterConfig, clip_from_view: &Mat4, view_from_world: &Mat4, size: (u32, u32), lights: &mut [PackedLight], )

Assign lights to the cells of cfg’s grid for this frame’s camera.

clip_from_view and view_from_world are the camera’s two transforms: depth and the screen extent come from them, so both are needed. size is the target’s pixel size.

lights is ranked by importance in place, so the caller passes them in any order and the weakest are what a full cell drops.
