As before ... fantastic article. I think you're being too hard on yourself. The concept of world/model space is pretty darn important to understand.

One question, I noticed in your Model3DCollection Example that you programmatically set the transform. If you're not doing the transforms and such declaratively through XAML, How is that handled in code? I mean, is there some sort of built in update/render loop where we can animate programmatically?

I just installed the winHEC build of longhorn on my laptop so I'm just getting a chance to start playing with this now. Keep the good stuff comin'

Joel - Avalon is primarily a retained graphics platform. The user provides a list of rendering instructions (in 3D this is in the form of a graph of Model3Ds) and attaches these instructions to Visual (in 3D, this is usually the ViewPort3D). When it is determined that this Visual may be on screen the rendering instructions are serialized and marshalled to a seperate thread which does the actual rendering. The render loop is entirely abstracted away from the user.

If you look at my first Avalon 3D demo (http://blogs.msdn.com/danlehen/archive/2004/06/01/146259.aspx) you will see that I am animating by poking in new Transform3Ds when I am called back with a UITimer. This works, but is not as elegant as some of the options available to you in 2D (http://longhorn.msdn.microsoft.com/?//longhorn.msdn.microsoft.com/lhsdk/port_task_animation.aspx). If you browse MSDN you will find that there are similar animation properties for 3D stubbed out, but unfortunately in the WinHEC build they are nonfunctional.
