WPF 3D - Detirmine whether a ModelVisual3D is being clipped inside it's Viewport3D

I have a cube rendering inside a Viewport3D and i need to know a way to find out whether ALL of the cube is visible to the user. Edit:Just to be clear,..I'm not talking about clipping because of the near/far plane distance here. I mean the cube is to tall or wide to fit in the cameras field of view. Any help would be massively appreciated! Thanks in advance.

Make a 3D model transparent

How can I make a specific 3d model transparent? Is it as simple as changing the opacity of the model's material? I tried the following: SolidColorBrush br = (SolidColorBrush)matDif.Brush; //matDif = DiffuseMaterial br.Opacity = 0.3; When it tries setting the opacity it says that it is in a read-only state and cannot be changed?
