Struct ExtractedScene 

pub struct ExtractedScene {
    pub render_items: Vec<ExtractedRenderItem>,
    pub scene_id: u32,
    pub scene_variants: SceneFeatures,
    pub scene_defines: ShaderDefines,
    pub background: BackgroundMode,
    pub envvironment: Environment,
    pub has_transmission: bool,
    pub lights: Vec<ExtractedLight>,
    /* private fields */
}

Extracted scene data

This is a lightweight structure containing only the minimal dataset needed for current frame rendering. Populated during Extract phase, after which the Scene borrow can be safely released.

“Single Source of Truth” Design

render_items is the single, unified list of all active renderables. No frustum culling is performed during extraction — that is deferred to the Cull phase where each RenderView (main camera, shadow cascades, etc.) performs its own culling against this shared list.

Fields

render_items: Vec<ExtractedRenderItem>

All active render items (NOT frustum-culled). Each RenderView in the Cull phase filters and culls from this list.

scene_id: u32

Scene’s shader macro definitions

scene_variants: SceneFeatures

scene_defines: ShaderDefines

background: BackgroundMode

envvironment: Environment

has_transmission: bool

lights: Vec<ExtractedLight>

Implementations

impl ExtractedScene

pub fn new() -> Self

Creates an empty extracted scene

pub fn with_capacity(item_capacity: usize) -> Self

Pre-allocates capacity

pub fn clear(&mut self)

Clear data for reuse

pub fn extract_into( &mut self, scene: &mut Scene, camera: &RenderCamera, assets: &AssetServer, resource_manager: &mut ResourceManager, )

Reuse current instance memory, extract data from Scene.

Extracts ALL active meshes into render_items without frustum culling. Frustum culling is deferred to the Cull phase where each RenderView independently culls from this unified list.

pub fn has_shadow_casters(&self) -> bool

pub fn render_item_count(&self) -> usize

Get render item count

pub fn is_empty(&self) -> bool

Check if empty

Trait Implementations

impl Default for ExtractedScene

fn default() -> Self

Returns the “default value” for a type.
