Typically, video has a beginning and an end, and the only interaction is to play, pause, forward or rewind. The videographer determines exactly what they want you to look at. 3D tours are completely interactive. You get to decide what you want to focus on, the angle you want to see it at, and how long you want to look at it. You are in complete control. You are able to navigate through the home at your own pace, whenever and as often as you like, while in the convenience of your own home.
