Can anyone please point me or send me a complete code that reads from these two cameras and give me the stereo picture. I just want to concentrate on my work... finding depth.

forgot to ask, how did you create your circle with gradient? I'd like to see the code that generated it, maybe I could still come up with a cheaper approach than painting all those rectangles...

private void CreateBrush()
{
    if(brush != null)
    {
        brush.Dispose();
    }
 
    Rectangle r = new Rectangle(Location, Size);
 
    PointF[] ptsF = 
    {
        new PointF(0, 0),
        new PointF(r.Width / 2, 0),
        new PointF(r.Width, 0),
        new PointF(r.Width, r.Height / 2),  
        new PointF(r.Width, r.Height),
        new PointF(r.Width / 2, r.Height),
        new PointF(0, r.Height),
        new PointF(0, r.Height / 2)
    };

    brush = new PathGradientBrush(ptsF);
 
    Color[] colors = 
    {
        Color.Gray,
        Color.White,
        Color.Gray,
        Color.DarkGray,
        Color.Gray,
        Color.White,
        Color.Gray,
        Color.DarkGray
    };
 
    brush.SurroundColors = colors;
 
    brush.CenterColor = Color.White;
