Methods

Methods Node מחלקה מייצגת אלמנט בעל שם בגרף הסצנה של Aspose.3D. כל צומת יכול להכיל אחד Entity (כגון Mesh או Camera), שומר על יחסי הורה‑צאצא עם צמתים אחרים, ונושא שינוי מקומי. צמתים הם הדרך העיקרית לארגן אובייקטים תלת‑ממדיים במבנה סצנה.

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());
}

Methods

צור סצנה, חבר mesh ל‑node, ועבור על גרף הסצנה:

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());
    }
