Flying Text in 3D (Silverlight) algorithm

I am trying to understand a code that I found online to fly the text in 3d using silverlight. The algorithm is not easy to understand for me as I am not familiar with these types of algos. Does somebody know a good book/resource that talks about these a开发者_运维知识库lgos?

It's not Silverlight-specific, but WPF Unleashed is a great reference text that includes chapters on 3d and animation. WPF is (for the most part) a superset of Silverlight's UI system, but most of the same principles apply.
