[Closed] camera cone object minus objects inside it?

I know there is a good script to create a cone object that mimics the camera cone (cameracone.ms: http://www.scriptspot.com/3ds-max/cameracone ).
Now I am thinking a way to improve it, cutting this cone with the objects inside the camera view.

Which is the best way to do it in MXS?
(Knowing that the objects and the camera will be animated)

1- May be a boolean operation?.
2- Creating a new mesh from the bounding box of the objects to a plane, perpendicular to the camera and far away?
3- Working with the TM in camera view?
4- …

Thanks
