public class SceneNode

SceneNode

Object in a scene graph. One parent per node; cycles are forbidden. Local transforms are immutable matrices. Meshes/materials can be shared. Example: node = SceneNode("robot", mesh, material); scene.root.add(node)

Properties

Modifier and Type	Member	Description
public readonly property	childCount `childCount as Int`	Number of children, O(1).
public property	isVisible `isVisible as Boolean = true`	Hides this entire subtree when false.
public property	material `material as Material`	Immutable material.
public property	mesh `mesh as Mesh`	Optional geometry.
public property	name `name as String`	Name for selection/debugging.
public readonly property	parent `parent as SceneNode`	Parent, or null for roots.
public property	transform `transform as Matrix4 = Matrix4()`	Local-to-parent transform.

Constructors

Modifier and Type	Member	Description
public	SceneNode `SceneNode(name as String = "", mesh as Mesh = null, material as Material = Material())`	Creates an object or grouping node.

Methods

Modifier and Type	Member	Description
public	add `add(child as SceneNode) as Void`	Attaches a detached node; rejects null, cycles and multiple parents.
public	bounds `bounds(parentTransform as Matrix4 = Matrix4()) as Bounds3d`	Computes visible world bounds, O(nodes), using cached mesh bounds.
public	childAt `childAt(index as Int) as SceneNode`	Returns child i in O(1).
public	clone `clone() as SceneNode`	Deep-copies the node hierarchy, sharing immutable meshes/materials.
public	remove `remove(child as SceneNode) as Boolean`	Detaches a child, returning whether it belonged to this node.
