I want to rotate the camera acording to the mouse position, and zooming using the mouse wheel. Is there anything ready to do this?

Something like a trackball.

There is no direct support for camera manipulation - you'd have to create this yourself. That being said, there is however interaction support for objects by saying InteractionEnabled="true" on objects in Xaml - that will enable mouse interaction with the objects themself.

Is there any way to group objects together so I can interact with them as one?

There is something called Container that you can use. Its an object for holding other objects.

Do you know in what namespace I can find this Container?

I found it. Thack you!

vmrocha,

wondering if you ever got a trackball working or just used Interaction.  I'm looking for a trackball if you implemented it. Thanks
