Node

Metodi

Methods Node class rappresenta un elemento nominato nel Aspose.3D scene graph. Ogni nodo può contenere uno Entity (come ad esempio un Mesh o 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());
}

Metodi

Crea una scena, collega una mesh a un nodo e attraversa il grafo della scena:

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());
    }
}
