Node

Node

Example

Example Node class represents a named element in the Aspose.3D scene graph. Each node can hold one Entity (such as a Mesh, Camera, or Light),.

using Aspose.ThreeD;

var scene = new Scene();

// Access the root node
Node root = scene.RootNode;

// Create a child node
Node child = root.CreateChildNode("my_node");

// Iterate child nodes
foreach (var node in root.ChildNodes)
{
    Console.WriteLine(node.Name);
}

Example

Signature	Description
`Node()`	Creates a node with name and attaches the given entity
`Node(name: string)`
`Node(name: string, entity: Entity)`
`CreateChildNode()`	Creates a child node
`CreateChildNode(nodeName: string)`	Creates a child node
`CreateChildNode(entity: Entity)`	Creates a child node
`CreateChildNode(nodeName: string, entity: Entity)`	Creates a child node
`CreateChildNode(nodeName: string, entity: Entity, material: Shading.Material)`	Creates a child node
`AddChildNode(node: Node)`	Add a child node to this node
`AddEntity(entity: Entity)`	Add an entity to the node.
`Merge(node: Node)`	Detach everything under the node and attach them to current node.
`EvaluateGlobalTransform(withGeometricTransform: bool)`	Evaluate the global transform, include the geometric transform or not.
`GetChild(index: int)`	Gets the child node at specified index.
`GetChild(nodeName: string)`	Gets the child node at specified index.
`Accept(visitor: NodeVisitor)`	Walks through all descendant nodes(including the current node) and call the visitor with the node. Visitor can break the walk-through by returning false
`GetBoundingBox()`	Calculate the bounding box of the node
`SelectSingleObject(path: string)`	Select single object under current node using XPath-like query syntax.
`SelectObjects(path: string)`	Select multiple objects under current node using XPath-like query syntax.
`ToString()`	Gets the string representation of this node.
`SceneObject(name: string)`
`A3DObject()`
`RemoveProperty(property: Property)`	Removes a dynamic property.
`GetProperty(property: string)`	Get the value of specified property
`SetProperty(property: string, value: object?)`	Sets the value of specified property
`FindProperty(propertyName: string)`	Finds the property. It can be a dynamic property (Created by CreateDynamicProperty/SetProperty) or native property(Identified by its name)

Example

using Aspose.ThreeD;
using Aspose.ThreeD.Entities;

var scene = new Scene();

// Build a hierarchy with entities
var parent = scene.RootNode.CreateChildNode("Parent");
parent.Transform.Translation = new FVector3(10, 0, 0);

var box = new Box(2, 2, 2);
var child = parent.CreateChildNode("BoxChild", box);
child.Transform.Translation = new FVector3(5, 0, 0);

scene.Save("hierarchy.gltf");
