Usually communication standards like UART/RS232 are used to establish an easy to use connection, while other standards like USB are difficult to handle and tend to be very complicated.

Getting started with 3D in WPF

Though WPF is not meant for complex 3D implementations, the Viewport3D is a quite powerful feature. You can implement small 3D Animations to improve your design, the usability and so on. However, the usage of this Viewport3D is not easy going. Usually (at least I do) you have created an 3D Object in a 3D Modeling...
