Setting it Up ,[object Object],[object Object],[object Object],nui = new Runtime (); try { nui.Initialize( RuntimeOptions .UseDepthAndPlayerIndex | RuntimeOptions .UseSkeletalTracking | RuntimeOptions .UseColor); } catch (InvalidOperationException) { return 42 ; }

Event-driven data streams ,[object Object],nui.DepthFrameReady += new EventHandler < ImageFrameReadyEventArgs > (nui_DepthFrameReady); nui.SkeletonFrameReady += new EventHandler<SkeletonFrameReadyEventArgs> (nui_SkeletonFrameReady); nui.VideoFrameReady += new EventHandler<ImageFrameReadyEventArgs> (nui_ColorFrameReady); void nui_ColorFrameReady( object sender, ImageFrameReadyEventArgs e) { PlanarImage Image = e.ImageFrame.Image; video.Source = BitmapSource .Create( Image.Width, Image.Height, 96, 96, PixelFormats .Bgr32, null , Image.Bits, Image.Width * Image.BytesPerPixel); }

What’s In A... ImageFrame ImageFrame We’ll cover this in more detail next week. For now, just know that you have access to the raw bytes (misnamed “bits”) that makes up the pixels
