Where can I find information about creating 3D controls in WPF?

I am about to start to make the interface for a game in WPF / Silverlight. I'd like it to have a nice look all in 3 dimensions. Can you point me to some good resources, tutorials, boo开发者_如何学运维ks... on how to develop real 3D controls, like Buttons and such?
