Node

Node

Methoden

Methods Node klasse vertegenwoordigt een benoemd element in de Aspose.3D scene graph. Elke node kan één bevatten Entity (zoals een Mesh of Camera), onderhoudt ouder‑kindrelaties met andere nodes, en draagt een lokale transformatie. Nodes zijn de primaire manier om 3D‑objecten in een scene‑hiërarchie te organiseren.

import com.aspose.threed.Scene;
import com.aspose.threed.Node;

Scene scene = new Scene();

// Access the root node via getter
Node root = scene.getRootNode();

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

// Iterate child nodes via getter
for (Node node : root.getChildNodes()) {
    System.out.println(node.getName());
}

Methoden

Methods Node constructor initialiseert een node met een optionele naam.

Methoden

Maak een scène, koppel een mesh aan een node, en doorloop de scènegrafiek:

import com.aspose.threed.Scene;
import com.aspose.threed.Node;
import com.aspose.threed.*;


Scene scene = new Scene();
Mesh mesh = new Mesh();
mesh.getControlPoints().add(new Vector4(0, 0, 0, 1));
mesh.getControlPoints().add(new Vector4(1, 0, 0, 1));
mesh.getControlPoints().add(new Vector4(0.5, 1, 0, 1));
mesh.createPolygon(0, 1, 2);

// Attach mesh to a child node
Node node = scene.getRootNode().createChildNode("triangle", mesh);

// Traverse child nodes using getter
for (Node child : scene.getRootNode().getChildNodes()) {
    Entity entity = child.getEntity();
    if (entity != null) {
        System.out.println("Node '" + child.getName() + "': " + entity.getClass().getSimpleName());
        System.out.println("  Excluded: " + child.getExcluded());
    }
}
