We learned a lot in this chapter about 3D models, meshes, and other elements. Specifically, we imported, exported and prepared 3D models using 3D DCC tools in order to load them in our applications. We showed models in XBAP WPF using XAML and in Silverlight applications using the services provided by a specialized 3D engine. We rendered and transformed the meshes in real-time using both hardware-based and software-based rendering processes. We understood the usage of a Silverlight 3D engine and we began controlling some aspects of the 3D elements.
