Node

Metode

Methods Node kelas mewakili elemen bernama dalam grafik adegan Aspose.3D. Setiap node dapat menampung satu Entity (seperti sebuah Mesh atau Camera), mempertahankan hubungan induk‑anak dengan node lain, dan membawa transformasi lokal. Node adalah cara utama untuk mengatur objek 3D dalam hierarki adegan.

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

Buat sebuah adegan, lampirkan mesh ke sebuah node, dan telusuri grafik adegan:

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());
    }
}
