    The authors report on a flexible system that provides visual feedback to VLSI designers with a novel display method. The basic problem is to display simultaneously two or more functions f/sub 1/, f/sub 2/, . . ., each of which depends on the two spatial variables x and y. The method is based on results from visual perception experiments, which indicated that the human visual system can view simult... View full abstract»

    To demonstrate the feasibility and practicability of designing and building low-cost flight simulators, a prototype system was developed to model the performance of a new US Army remotely piloted missile system. The flight simulator displays a dynamic, three-dimensional, out-the-window view of the terrain in real time while responding to operator input from the command and control system. A descri...

    The author discusses data representations and analytical tools commonly used in solid modelers for three analysis operations: boundary evaluation, image generation, and mechanical property calculation. The methods described are generally applicable to solid models bounded by quadric surfaces (e.g. planes, cylinders, spheres, and cones). Only methods applicable to constructive solid geometry or bou... View full abstract»

    The design of HutWindows, a user interface management system intended for applications in mechanical CAD, is discussed,. HutWindows features a three-layered internal architecture, where the presentation, dialogue-control, and application-processing layers are clearly separated from each other. This leads to increased simplicity and flexibility in user interface design over the more traditional sit... View full abstract»

    An algorithm is described for partitioning intersecting polyhedrons into disjoint pieces and, more generally, removing intersections from sets of planar polygons embedded in three space. Polygons, or faces, need not be convex and may contain multiple holes. Intersections are removed by considering pairs of faces and slicing the faces apart along their regions of intersection. To reduce the number ... View full abstract»

    A macro facility that allows end users to extend interactive graphical applications is presented as part of a user-interface management system (UIMS). Such macros are expressed by example; that is, the end user programs the macro in the application's generated user interface. Problems with macros-by-example in graphical applications are explored, and requirements to accommodate such a facility are... View full abstract»
