Node

Node

Metode

Methods Node clasa reprezintă un element denumit în graficul de scenă Aspose.3D. Fiecare nod poate conține unul Entity (cum ar fi un Mesh sau Camera), menține relații părinte-copil cu alte noduri și poartă o transformare locală. Nodurile sunt modalitatea principală de a organiza obiecte 3D într-o ierarhie de scenă.

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());
}

Metode

Creează o scenă, atașează un mesh la un nod și parcurge graful de scenă:

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());
    }
}
