Abstract
This disclosure describes a method for camera/user view navigation about enclosed 3D environment (e.g., the inside of a sports stadium or arena). The navigation system constrains the user view (camera) to a (pre-defined) guide based on the shape and size of the interior area which is the focus of the 3D virtual world. In the case of an arena this would generally be the playing surface. The user can easily control the camera movement on this guide with traditional up/down and left/right controls. These controls could be implemented as buttons within the application, keyboard controls, or mouse controls.
