Struct SceneTransforms 

pub struct SceneTransforms {
    pub local: Vec<Transform>,
    pub world: Vec<GlobalTransform>,
    pub dirty: Vec<bool>,
}

Per-entity transform storage (SoA layout).

Fields

local: Vec<Transform>

Local-space transforms (TRS).

world: Vec<GlobalTransform>

World-space transforms (4x4 matrices).

dirty: Vec<bool>

Dirty flags — set when local transform changes.

Implementations

impl SceneTransforms

pub fn with_capacity(capacity: usize) -> Self

Create with pre-allocated capacity. All transforms start at identity.

pub fn mark_dirty(&mut self, entity: u32)

Mark an entity’s transform as dirty (needs world recalculation).

pub fn propagate_from_roots(&mut self, hierarchy: &SceneHierarchy)

Propagate transforms from roots through hierarchy. BFS: for each root, compute world = local.to_matrix(). For each child, compute world = parent_world * child_local.

pub fn len(&self) -> usize

Number of entity slots.

pub fn is_empty(&self) -> bool

Whether the store is empty.

Trait Implementations

impl Clone for SceneTransforms

fn clone(&self) -> SceneTransforms

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SceneTransforms

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

Formats the value using the given formatter.
