Создание точки на лбу kinect C# wpf

Question

Я хочу, чтобы сделать точку на моем лбу, используя образец «Основы отслеживания лица WPF» от Kinect для Windows Developers Toolkit v1.7.0. Кто-нибудь знает?

окончательно я сделал его успешным. это шаг. открытым FaceTrackingViewer.xaml

заменить "DrawFaceModel" с:

public void DrawFaceModel(DrawingContext drawingContext) 
     { 
      if (!this.lastFaceTrackSucceeded || this.skeletonTrackingState != SkeletonTrackingState.Tracked) 
      { 
       return; 
      } 

      var faceModelPts = new List<Point>(); 
      var faceModel = new List<FaceModelTriangle>(); 
      //double[] xarray; 
      //double[] yarray; 

      for (int i = 0; i < this.facePoints.Count; i++) 
      { 
       faceModelPts.Add(new Point(this.facePoints[i].X + 0.5f, this.facePoints[i].Y + 0.5f)); 
       //xarray[i] = this.facePoints[i].X; 
       //yarray[i] = this.facePoints[i].Y; 
      } 

      // double xpos21 = this.facePoints[21].X; 
      //double xpos21 = this.facePoints[21].X; 
      //Bikin Titik di jidat 


      foreach (var t in faceTriangles) 
      { 
       var triangle = new FaceModelTriangle(); 
       triangle.P1 = faceModelPts[t.First]; 
       triangle.P2 = faceModelPts[t.Second]; 
       triangle.P3 = faceModelPts[t.Third]; 
       faceModel.Add(triangle); 
      } 

      // ColorImagePoint j1p = faceModelPts.Add(new Point(this.facePoints[1].X + 0.5f, this.facePoints[1].Y + 0.5f)); 
      // ColorImagePoint j1p = myKinect.MapSkeletonPointToColor(faceModelPts[1].Position, ColorImageFormat.RgbResolution640x480Fps30); 



      //var faceModelGroup = new GeometryGroup(); 
      //for (int i = 0; i < faceModel.Count; i++) 
      //{ 
      // var faceTriangle = new GeometryGroup(); 
      // faceTriangle.Children.Add(new LineGeometry(faceModel[i].P1, faceModel[i].P2)); 
      // faceTriangle.Children.Add(new LineGeometry(faceModel[i].P2, faceModel[i].P3)); 
      // faceTriangle.Children.Add(new LineGeometry(faceModel[i].P3, faceModel[i].P1)); 
      // faceModelGroup.Children.Add(faceTriangle); 
      //} 

      var faceModelGroup = new GeometryGroup(); 
      //for (int i = 0; i < faceModel.Count; i++) 
      //{ 
       var faceTriangle = new GeometryGroup(); 
       faceTriangle.Children.Add(new LineGeometry(faceModel[1].P1, faceModel[1].P2)); 
       faceTriangle.Children.Add(new LineGeometry(faceModel[1].P2, faceModel[1].P3)); 
       faceTriangle.Children.Add(new LineGeometry(faceModel[1].P3, faceModel[1].P1)); 

       faceModelGroup.Children.Add(faceTriangle); 
      //} 
       //((MainWindow)System.Windows.Application.Current.MainWindow).jidat1.Content = Math.Round(facePoints[1].X,3); 
       //((MainWindow)System.Windows.Application.Current.MainWindow).jidat2.Content = Math.Round(facePoints[1].Y,3); 

      drawingContext.DrawGeometry(Brushes.LightYellow, new Pen(Brushes.LightYellow, 1.0), faceModelGroup); 
      //drawingContext.DrawEllipse(Brushes.LightYellow, new Pen(Brushes.LightYellow, 1.0), faceModelPts[1]); 


     } 

вы получите треугольник на лице
