ABSTRACT:
Peripheral lenses provide simulated peripheral vision on a display device. One or more peripheral lenses may be provided to generate peripheral views corresponding to portions of peripheral vision. In a first alternative, multiple viewing frustums are utilized. A first viewing frustum is utilized to define a main view of a scene and additional viewing frustums are defined for each peripheral lens. The viewing frustums of the peripheral lenses are angularly offset relative to the viewing frustum for the main view and share a boundary with the viewing frustum for the main view. In a second alternative, a reflective object is positioned within a scene to yield peripheral views of the scene. Environment mapping is employed to determine how objects in the scene are reflected off the reflective object. The reflective object may be dynamically altered to modify the resulting peripheral view.
