This week Aaron Oneal, program manager of the Silverlight 3D efforts, joins John to discuss the 3D APIs in Silverlight 5 beta. Aaron was instrumental in working on the 3D features and helped to create the 3D Solar Wind and 3D HouseBuilder demos. Aaron reviews the features and explores how they all work by demoing the Solar Wind sample application. This is a great walk through of a nice app that you can apply to your own 3D efforts.
