THE DESIGN OF A USER INTERFACE FOR A CAM APPLICATION
(The Eurographics Association, 1984)This paper describes a user interface which has been designed for the rough environment of a workshop floor. It has a strictly hierarchical structure of the commands, but allows a lot of context-free operator's actions and ... -
THE DEVELOPMENT OF COMPUTER GRAPHICS CURRICULA FOR DESIGN EDUCATION
(The Eurographics Association, 1984)With the imminent availability of low cost, high resolution computer graphics systems suitable for visual and graphic arts applications, design education must now come to terms with radical changes in design methodology ... -
DIRECT CADD DRAWING (A Flexible Screen Oriented user interface to CADD)
(The Eurographics Association, 1984)Computer aided design/drafting (CADD) system developers are taking advantage of the latest developments in personal computing and human factors research by including icon (picture) driven, direct manipulation menus in a ... -
DRAWING OF AN UNUSUAL KIND OF DIAGRAMS - NOMOGRAM DRAWING
(The Eurographics Association, 1984)Diagram drawing has traditionally been a major part of computer graphics applications. During the last few years we have seen new trends in this area. The quality of diagram drawing has increased and diagrams has been used ... -
EXPERIENCES WITH NEW IMAGE COMPONENT ALGORITHMS
(The Eurographics Association, 1984)We present experiences and comparisons evaluating a fast algorithm for connected component labeling of quad- and octrees. The algorithm works without loss of efficiency on linear tree representations that may reside in ... -
GENERATING HIGH QUALITY PICTURES BY RAY-TRACING
(The Eurographics Association, 1984)Ray-casting techniques provide a very general framework in which many problems can be solved in a much easier way than with conventional methods. This is particularly true for the illumination model when a high level of ... -
GRAPHICAL SUPPORT IN A USER INTERFACE MANAGEMENT SYSTEM
(The Eurographics Association, 1984)SYNICS2 is a User Interface Management System (UIMS) using the concept of Recursive Transition Networks (RTN) for its control structure. It is used as an intelligence terminal would be, being situated between the computer ... -
HOW INTELLIGENT CAN BUSINESS GRAPHICS SOFTWARE BE?
(The Eurographics Association, 1984)This paper justifies the question posed in its title, by pointing out some of the reasons which make the use of a "quasi" automatic system necessary, when customized performances of the intelligence built in a business ... -
IMPROVING COMPUTER GRAPHICS TOOLS FOR ARCHITECTS
(The Eurographics Association, 1984)During the last ten years a lot of work has been done in architectural applications using computers and especially computer graphics. It is however obvious that these new tools have not been fully accepted by architects ... -
INTERACTIVE EDITING OF POLYGONS
(The Eurographics Association, 1984)This paper describes an internal data structure which can be used in interactive editing of polygons. A user can delete, restore, split and merge polygons and change type and direction of polygons. The polygons that are ... -
A NEW DISPLAY FILE STRUCTURE FOR LINE AND SURFACE PRESENTATIONS
(The Eurographics Association, 1984)In the design process of 3D objects i t will be helpful to use not only an output pipeline design for a wire frame model on a vector device but also for shaded surface presentations on a raster device. To reduce the total ... -
NUMERICAL SIMULATION AND VIDEO DISPLAY OF DYNAMIC PROBLEMS
(The Eurographics Association, 1984)The increasing ability of computers to digest and regurgitate numerical results requires graphic displays which allow new and complex problems to be dealt with. In this paper we present software designed to study phenomena ... -
A PAINT PROGRAM FOR THE GRAPHIC ARTS IN PRINTING
(The Eurographics Association, 84)There is considerable scope for the application of computer techniques to help the graphic designer working with printed products, provided that pictures of high technical quality result. Described here is the product of ... -
QUADTREE SCAN CONVERSION
(The Eurographics Association, 1984)An efficient method is described for turning a quadtree encoding of an image into scan lines. When implemented in hardware it becomes possible to generate video in real time for a raster display without the need for a ... -
RAY TRACING OBJECTS DEFINED BY SWEEPING A SPHERE
(The Eurographics Association, 1984)The basic calculation underlying ray tracing is that of the intersection of a line with the surfaces of an object. A method is presented here for performing this calculation for a new and powerful class of objects, those ... -
SHAPING THE FUTURE A SYSTEMS APPROACH TO MIS PLANNING
(The Eurographics Association, 1984) -
STEPS TO EFFECTIVE BUSINESS GRAPHICS
(The Eurographics Association, 1984) -
SUDS - SUrface Description System
(The Eurographics Association, 1984)A library of routines has been developed for the design of arbitrarily curved three-dimensional surfaces. The routines provide for the description and editing of surfaces. Surfaces are defined by families of parametric ... -
Three-Dimensional Data Input by Selection of Hierarchically Defined Blocks
(The Eurographics Association, 1984)This paper discusses inputing three dimensional solid object data by means of a two dimensional tablet. This method involves refining an object by gradually generalizing a class of 'permissible' objects. The design of an ... -
Twixt: A 3D Animation System
(The Eurographics Association, 1984)This paper describes a visually interactive 3D computer animation system. Animation is controlled by lists of events stored in tracks. Tracks are interpolated by functions that have an arbitrary degree of knowledge about ...
