Multi-touch is the way to go!

Touch API

Silverlight-specific FrameReported event

message source

Let’s go crazy with effects!

demoMessing around with the Plural website

Effects aka Pixel Shaders

• Effects can be applied to ANY control– Can be controlled with

storyboards/behaviors/code

• Written in HLSL (High Level Shader Language)– Tip: use Walt Ritscher’s Shazzam Tool

• Lots of effects available open source

WriteableBitmap

• Any control can be rendered to a WriteableBitmap– This includes control trees

• WriteableBitmap is a control: you can apply effects to it

• Image encoders available on the web (PNG, …)

• Check Rick Barraza’s blog (Cynergy):– Fluid Dynamics in Silverlight– Advanced Render Techniques with WriteableBitmaps

The new stuff!Some of Silverlight 4 new features

Full HTML Support

• WebBrowser control– Source property• Sets HTML content

– Navigate(uri) method• Navigates to the specified URI

• Yes, it’s as simple as that!

WebCam and Mic Accessprivate void btnStartCapture_Click(object sender, RoutedEventArgs e){ if (_captureSource != null) { // stop whatever device may be capturing _captureSource.Stop(); _captureSource.VideoCaptureDevice = (VideoCaptureDevice) WebCamList.SelectedItem; _captureSource.AudioCaptureDevice = (AudioCaptureDevice) MicrophoneList.SelectedItem; VideoBrush vidBrush = new VideoBrush(); vidBrush.SetSource(_captureSource); ViewBox.Fill = vidBrush; // request access to webcam and audio devices if (CaptureDeviceConfiguration.AllowedDeviceAccess || CaptureDeviceConfiguration.RequestDeviceAccess()) { _captureSource.Start(); } }}
