An Open Model for Hypermedia and Its Application to Geographical Information Systems
(Blackwell Science Ltd and the Eurographics Association, 1992)
This paper describes the design and implementation of a multimedia information management environment that is based on an open model for hypermedia. The model, known as Microcosm, is currently implemented in Microsoft ...
SX/Tools - An Open Design Environment for Adaptable Multimedia User Interfaces
(Blackwell Science Ltd and the Eurographics Association, 1992)
In this paper a brief review of user interface management systems (UIMSs) and their advantages is given. Shortcomings of current UIMSs and open requirements imposed by industrial application areas are outlined. Among the ...
Computing Dynamic Changes to BSP Trees
(Blackwell Science Ltd and the Eurographics Association, 1992)
This paper investigates a new method for dynamically changing Binary Space Partition (BSP) trees. A BSP tree representation of a 3D polygonal scene provides an ideal data structure for rapidly performing the hidden surface ...
A Development Environment for Constructing Graph-Based Editing Tools
(Blackwell Science Ltd and the Eurographics Association, 1992)
Scientists and engineers use numerous kinds of graph notations to model various objects in the real world and their relationships in an abstract pictorial form. However, developing a specific graph editing tool for each ...
Modeling with Time and Events in Computer Animation
(Blackwell Science Ltd and the Eurographics Association, 1992)
In this paper, we present a general, systematic and consistent treatment of time and events for computer animation. We first formalize the concepts of events and create a time primitive called an event unit. We then present ...
Fractals and Solid Modeling
(Blackwell Science Ltd and the Eurographics Association, 1992)
Trying to combine fractal geometry and solid modeling seems to be a contradiction in itself, In this paper a new type of 3D objects is presented that accomplishes this combination in a specific way. Objects with a fractal ...
Composing Hierarchically Structured Images
(Blackwell Science Ltd and the Eurographics Association, 1992)
This paper begins by examining the classical raster-based composition model, establishing its weakness, and developing a new composition algebra based on line drawing. It then examines the role of composition in the ...
A Functional Approach to the Visual Simulation of Gaseous Turbulence
(Blackwell Science Ltd and the Eurographics Association, 1992)
This paper presents a functional method for the visual simulation of 2-D or 3-D turbulent gaseous motion by using time-varying fractals. The used function incorporates results from the"spectral theory of turbulence", thereby ...
A Unified Approach for Physical and Geometric Modeling for Graphics and Animation
(Blackwell Science Ltd and the Eurographics Association, 1992)
We present a unified approach for geometric and physical modeling using implicit functions, for application to graphics and animation. This method extends previously proposed techniques, and allows the standard finite ...
Realistic Generation and Real Time Animation of Images of the Human Colon
(Blackwell Science Ltd and the Eurographics Association, 1992)
A simulator has been built to teach doctors the skill of handling a flexible endoscope for gastrointestinal investigations. Trainees use a dummy endoscope in which the control actions are transduced into voltages and sensed ...
