Struct SceneNode 

pub struct SceneNode {
    pub name: String,
    pub transform: Transform,
    pub mesh: Option<MeshBuffers>,
    pub children: Vec<SceneNode>,
}

A node in the scene graph.

Fields

name: String

transform: Transform

mesh: Option<MeshBuffers>

children: Vec<SceneNode>

Implementations

impl SceneNode

pub fn new(name: impl Into<String>) -> Self

Create a new node with the given name, identity transform, no mesh, no children.

pub fn with_transform(self, t: Transform) -> Self

Builder-style: set the transform.

pub fn with_mesh(self, mesh: MeshBuffers) -> Self

Builder-style: attach a mesh.

pub fn add_child(&mut self, child: SceneNode)

Add a child node.

pub fn node_count(&self) -> usize

Count total nodes: self plus all descendants (recursive).

pub fn mesh_count(&self) -> usize

Count nodes that carry a mesh: self (if mesh is Some) plus all descendants.

pub fn all_names(&self) -> Vec<String>

Collect all node names in depth-first (pre-order) traversal.
