Nonimmersive virtual reality (VR), which places the user in a 3D environment that can be directly manipulated with a conventional graphics workstation using a monitor, a keyboard; and a mouse, is discussed. The scene is displayed with the same 3D depth cues used in immersive VR: perspective view, hidden-surface elimination, color, texture, lighting, shading and shadows. As in immersive VR, animation and simulation are interactively controlled in response to the user's direct manipulation. Much of the technology used to support immersive and nonimmersive VR is the same. They use the same 3D modeling and rendering and many of the same interaction techniques. The advantages and applications of nonimmersive VR systems are discussed. Immersive and nonimmersive VR systems are compared and hybrid possibilities are reviewed.<>
