Direct volume display devices

摘要

Direct volume display devices (DVDDs), which display 3D volumes and surfaces in a volume by providing depth rather than depth cues, are discussed. The transport theory model is used to illustrate why DVDDs are best able to support fast presentation from arbitrary directions. The technology underlying various DVDDs is described. Specifically, the design and operation of the OmniView rotating-screen DVDD are examined. The air-traffic-control/air-tactics-analysis, satellite orbit mechanics, and time-critical target prosecution applications of DVDDs are also discussed.
