The 3D remote interview was introduced as the "hologram" effect during CNN's 2008 presidential election coverage. Utilizing VirtualVU's remote rig setup, an array of cameras is able to capture images of the remote subject from a variety of angles. Servers then take information from the main studio tracking cameras and generate a 3D model of the remote subject from the exact perspective that is being captured in the main studio. These images are then combined and displayed to the viewer as if both subjects are standing side-by-side in a real-world main studio or virtual set, creating the appearance of an engaging, face-to-face conversation.
