Struct LightingPlan 

pub struct LightingPlan {
    pub world_rect: [f32; 4],
    pub layers: u32,
    pub layer_clamp: u32,
    pub lights: Vec<PlannedLight>,
    pub ambient: AmbientLight,
    pub issues: Vec<LightIssue>,
    pub occluder_rejects: Vec<OccluderReject>,
    pub culled: usize,
}

Everything the GPU pass needs for one frame, decided on the CPU.

Fields

world_rect: [f32; 4]

Visible world rect the accumulator covers: [x, y, w, h] with x/y the top-left (the accumulator’s uv origin).

layers: u32

Accumulator layers, including the trailing identity layer items with no layer read. At least 2, because a one-layer array texture is unsafe to sample on GL/ANGLE (see atlas_shape).

layer_clamp: u32

layers - 1: the highest index an item may sample.

lights: Vec<PlannedLight>

Lights in accumulation order.

ambient: AmbientLight

The ambient light, resolved per layer by Self::ambient_rgb.

issues: Vec<LightIssue>

Every light the plan altered or dropped, in input order.

occluder_rejects: Vec<OccluderReject>

Occluders rejected before any light was planned.

culled: usize

Lights skipped because their footprint misses the visible rect. Culling is not a budget drop, so these are counted, not reported.

Implementations

impl LightingPlan

pub fn wedge_vertices(&self) -> usize

Vertices all lights’ wedges need.

pub fn ambient_rgb(&self, layer: u32) -> [f32; 3]

Ambient rgb added to layer before any light: color * energy when the ambient’s mask reaches the layer. The trailing identity layer is always [0, 0, 0], so unlit items stay exactly unlit.
