Node
Metódusok
Methods Node class egy névvel ellátott elemet képvisel a Aspose.3D jelenet gráfban. Minden csomópont egyet tarthat Entity (például egy Mesh vagy Camera).
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());
}Metódusok
Methods Node fenntartja a szülő‑gyermek kapcsolatokat más csomópontokkal, és helyi transzformációt hordoz. A csomópontok az elsődleges módja a 3D objektumok szervezésének egy jelenet hierarchiában.

Hozzon létre egy jelenetet, csatoljon egy mesh-et egy csomóponthoz, és járja be a jelenet gráfot:

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());
