Hasilkan Point Cloud ke STL melalui C#

//File sumber yang perlu menghasilkan titik cloud
string file = "template.stl";

// buat instance Scene
Scene scene = new Scene(file);

//Dapatkan objek pointcloud dari Aspose.3D dan hasilkan point cloud
var pc = new PointCloud();
scene.RootNode.Accept((Node n) =>
{
    if (n.Entities.Count > 0)
    {
        var transform = n.EvaluateGlobalTransform(true);
        foreach (var entity in n.Entities)
        {
            if (entity is Geometry g)
            {
                Merge(pc, g, transform);
            }
            else if (entity is IMeshConvertible mc)
            {
                var mesh = mc.ToMesh();
                Merge(pc, mesh, transform);
            }

        }
    }
    return true;
});

//Metode penggabungan untuk menghasilkan awan titik
private void Merge(PointCloud pc, Geometry g, Matrix4 transform)
{
    var tmp = PointCloud.FromGeometry(g, 10);
    for (int i = 0; i < tmp.ControlPoints.Count; i++)
    {
        var pt = transform * tmp.ControlPoints[i];
        pc.ControlPoints.Add(pt);
    }
}

// buat instance dari newScene
var newScene = new Scene(pc);

//Saat menyimpan, Anda perlu membuat objek SaveOptions dengan format simpan
