Compositing for Interview

It seems like most compositing techniques are good for still pictures like masks and such but what would be a few good ones for actually showing someone a 3d Model and not just pics? I plan to show a model during an interview and wanted to know a few of the tricks. I’ve already seen depth of field in action but are there others?

I’m not sure why you think it’s limited to still images. The raison d’etre of the camera tracker is so that you can composite 3D elements into live-action video. Comp a model into some video so that it looks like it’s a real object. That should wow 'em.
