Struct SceneGraph 

pub struct SceneGraph { /* private fields */ }

A flat scene graph with parent-child node relationships.

Implementations

impl SceneGraph

pub fn new() -> Self

pub fn create_root(&mut self, position: Vec3) -> NodeId

Allocate a new root node.

pub fn create_child(&mut self, parent: NodeId, position: Vec3) -> Option<NodeId>

Allocate a new node with a parent.

pub fn get(&self, id: NodeId) -> Option<&SceneNode>

Get a node by ID.

pub fn get_mut(&mut self, id: NodeId) -> Option<&mut SceneNode>

Get a mutable node by ID.

pub fn remove_subtree(&mut self, id: NodeId) -> usize

Remove a node and all its descendants. Returns the count of removed nodes.

pub fn flush_transforms(&mut self)

Update world transforms for all dirty nodes (depth-first from roots).

pub fn find_by_tag(&self, tag: &str) -> Vec<NodeId>

Find all nodes with a specific tag.

pub fn visible_sorted(&self) -> Vec<NodeId>

Find all visible nodes sorted by sort_key.

pub fn len(&self) -> usize

Number of nodes in the graph.

pub fn is_empty(&self) -> bool

pub fn iter(&self) -> impl Iterator<Item = &SceneNode>

Iterate over all nodes.
