I tried your Triple demo and like it very much. It is such a great project.
However, I have one thing that I can not figure it out.
To use your BlogRoll3D project as a example, What I want to do is:
Whenever a ContentControl3D in the collection is moved to the most front in Panel3D, it will automatically rotate to the detail (back) view. Others in the collection will be still show the front view.
I am using the M-V-VM, how can I do this in the viewmodel class? Thanks.
