摘要： The information explosion is changing the daily lives of the "wired" population. Increasing numbers of individuals are being empowered to act as their own infor- mation brokers, interacting with large and expanding data spaces, for exampl e the World Wide Web. Scientists too are dealing with growing databases of empiric al and simulated information. New tools for visualizing these spaces are being developed which incorporate three-dimensional visual representations of information. These three-dimensional representations are believed to leverage the individual's capacity for comprehension and navigation in our three-dimensional world. In practice one is faced with the inherent limitations of 2D presentation and interaction throu gh the traditional two-dimensional desktop computer display. The spatial limitations of the two-dimensional display (referred to as the "screen real-estate problem") have motivated the development of detail-in-context methods of information presentation and exploration. Much of the work in this field has concen- trated on presentation methods for 2D information spaces. While a few techniques have incorporated 3D interaction metaphors, such as surfaces which produce m ag- nification through perspective distortion, fewer still have focused on techniques for interaction with3D representations of information. Three-dimensional representa- tions of information present specific challenges not found in 2D representations, for example the effect of occlusion on the visibility of elements. Traditional approaches to dealing with occlusion in three-dimensional representations include techniqu es such as cutting planes, viewer navigation, filtering of information and transparency. While these methods provide clearer visual access to elements of interest it is often at the expense of removing much of the contextual information from a representation .

摘要： In a data processing system that executes a program of instructions, a method for generating a detail-in-context presentation of a three-dimensional information representation comprising the steps of selecting a object-of-interest in the information representation; selecting a viewpoint; selecting a path from the viewpoint to the object-of-interest; and, displacing objects in the information representation away from the path to locations within the information representation where the objects remain visible when viewed from the viewpoint yet do not occlude the object-of-interest when viewed from the viewpoint to thereby generate the detail in context view.
