Drawing Pixels in WPF

Question

how would I manage pixel-by-pixel rendering in WPF (like, say, for a raytracer)? My initial guess was to create a BitmapImage, modify the buffer, and display that in an Imag

Answer 1

you could place 1X1 Rectangle objects onto a Canvas

  private void AddPixel(double x, double y)
  {
     Rectangle rec = new Rectangle();
     Canvas.SetTop(rec, y);
     Canvas.SetLeft(rec, x);
     rec.Width = 1;
     rec.Height = 1;
     rec.Fill = new SolidColorBrush(Colors.Red);
     myCanvas.Children.Add(rec);
  }

That should be pretty close to what you want
