TCD.Web.NotiConn – communicate between handsets without a server

Two days ago, when I was cycling, suddenly I had the answer: Imagine you have two Windows Phone 7 devices and want to establish a two-way connection between them. For example to play a game of Tic-Tac-Toe. You can do this either with a server on the internet, that connects the clients with each other, or the multicast protocol on WiFi-networks. The same WiFi network may not always be available to both users, but you don’t want to set up a server either (maybe, because you’re only doing this for fun, or you don’t have the resources). The only way to send messages to a WP7 app via the internet is to use push notifications. But how do you exchange the channel addresses between the devices? One way is to use a QR code: Establish a push notification channel on both devices Encode the channel URI into a QR code…

TCD.Mathematics

UPDATE: Source and samples for WinRT and WPF are now on GitHub: https://github.com/michaelosthege/TCD.Mathematics This is just a quick post to introduce you to TCD.Mathematics, which is a NuGet package that adds several extension methods to the System.Windows.Media.Media3D namespace. If you’re unfamiliar with this namespace, it contains Point3D, Vector3D, Line3D and Plane3D classes which can be used for three-dimensional calculations. EDIT: I just submitted an update to the NuGet package, wich adds support for WinRT. Please not that WinRT does not have neither Point3D, Vector3D, nor the System.Windows.Media.Media3D namespace. So in WinRT all classes, including substitutes for Point3D/Vector3D are located under TCD.Mathematics. EDIT: Since version 1.2.0 TCD.Mathematics is a Portable Class Library that targets everything: Silverlight 4+, .NET4+, .NET for Windows Store, Windows Phone 7+, Xbox360 – make sure you’re running version 2.1+ of NuGet Package Manager! The extension methods, which are added to the mentioned Point3D/Vector3D classes are: Vector3D.AsPoint3D() Point3D.AsVector3D() Vector3D.Normalized() Point3D.CenterOfClusterWithOtherPoint3Ds () Point3D.ProjectOnLine3D() Point3D…

TCD.Kinect

EDIT: If you’re interested in Skeleton tracking and calculating 3D stuff, take a look at TCD.Mathematics too^^ EDIT: There’s a WPF application that I once wrote, featuring SkeletonPainter3D: Kinect Sword. There’s a Youtube video of it (http://youtu.be/2j6GCd4M1bA) and that’s the source code: http://dl.dropbox.com/u/7813771/Blog/CodeSamples/KinectSword.zip   Hello there, I’ve created another UserControl, this time for Kinect and .NET 4.5, which hopefully has the potential to save you a lot of time. It can be used to draw three-dimensional Skeletons and explore the virtual space around them in real-time. A picture may be more appropriate: The control can be constructed in XAML: xmlns:kinect=”clr-namespace:TCD.Kinect.Controls;assembly=TCD.Kinect.Controls” <kinect:SkeletonPainter3D x:Name=”painter” Background=”Black” IsAnaglyphEnabled=”False” CameraFieldOfView=”70″ CameraPosition=”0,0.5,-1″ CameraLookAt=”0,0,2″ /> And populated with Skeletons using painter.Draw(skeletons), where skeletons is an Skeleton[] from inside the SkeletonFrameReady event. You can either get the TCD.Kinect package from NuGet, or refer to the sample implementation: http://code.msdn.microsoft.com/Implementation-of-f175b025 Let me know if you have any questions or suggestions, and by the way: SkeletonPainter3D has an experimental…
