iObject .net 11.1.1   vs2022  win11 x64

问题详细描述：通过上一步获得的二维点的坐标，将x，y赋值给三维点，z值设为2。将这个三维点通过添加到TrackingLayer展现在当前的Scene中，但是，我无法在当前的Scene看到我添加的TrackingLayer，或者TrackingLayer上的三维点和 geoText

if (rs.GetGeometry().Type == GeometryType.GeoPoint)//点类型
{
    GeoPoint pt=rs.GetGeometry() as GeoPoint;               
    GeoStyle geoStyle_P = new GeoStyle();                
    geoStyle_P.FillBackColor = Color.Red;
    geoStyle_P.FillForeColor = Color.Red;
    geoStyle_P.MarkerSize = (new Size2D(20, 20));
    pt.Style= geoStyle_P;
    _map.TrackingLayer.Add(pt,"");
    //_map.ViewBounds = pt.Bounds;
    _map.RefreshTrackingLayer();
    _map.Refresh();
   //Layer3DDataset layer3DDataset=_scene                             
    GeoPoint3D geoPoint3D =new GeoPoint3D();               
    geoPoint3D.X = pt.X;
    geoPoint3D.Y = pt.Y;
    geoPoint3D.Z = 2;                                
    GeoStyle3D geoStyle3D = new GeoStyle3D();
    geoStyle3D.AltitudeMode = AltitudeMode.RelativeToGround;
    geoStyle3D.BottomAltitude = 0;
    geoStyle3D.ExtendedHeight = 20;               
    geoPoint3D.Style3D= geoStyle3D;                
    _scene.TrackingLayer.Add(geoPoint3D , "");

    string text = "Test";
    TextPart textpart = new TextPart(text, geoPoint3D.X, geoPoint3D.Y, 3);
    GeoText geoText = new GeoText(textpart);
    geoText.TextStyle.ForeColor = System.Drawing.Color.Red;
    geoText.TextStyle.BackColor = System.Drawing.Color.AliceBlue;
    geoText.TextStyle.Shadow = true;
    geoText.TextStyle.ShadowColor = System.Drawing.Color.AliceBlue;
    geoText.TextStyle.Bold = true;
    _scene.TrackingLayer.Add(geoText, text);
    _scene.Refresh();
   
  
}

您好，添加跟踪图层不同对象时，TrackingLayer.Add时，不同对象请给不同的tag标签，

因为tag作为不重复的唯一值标识不同的跟踪图层对象。

三维场景中使用对象请使用GeoText3D。

希望可以帮助到您。
