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 ...
Interaction Management in CAD Systems with History Mechanism
(Eurographics Association, 1987)
User friendliness is one of the unresolved problems in CAD systems. There are many possible directions for improving user friendliness. Understanding of the modeling process is one of the most important directions. It is ...
Visualisation in Astrophysics
(Eurographics Association, 1989)
This paper reports on progress we have made in modelling cosmic X-ray sources on supercomputers. The results we present are meant to serve as an example for the fact that sophisticated visualization techniques play a crucial ...

Two Object-Oriented Models to Design Graphical User Interfaces
(Eurographics Association, 1989)
Object-oriented concepts are well-suited to deal with the characteristics of user interfaces. Up to now several attempts to integrate the object-oriented paradigm in user interface models were evolved and led to distinctive ...
DRAW - A GRAPHICAL PROGRAM WITH THE ABILITY TO DRAW CHEMICAL FORMULAE
(The Eurographics Association, 1980)
DRAW is a program that allows the user to produce diagrams on the incremental plotter or other graphical display devices by means of simple instructions. Particular requirements for chemical formulae have been catered for, ...
The Structure of Tube - A Tool for Implementing Advanced User Interfaces
(Eurographics Association, 1989)
Good user interfaces are very costly to implement and maintain. As user interfaces become more advanced, moving to various forms of direct manipulation, they become even more expensive and difficult to implement. In the ...
GKS in C
(The Eurographics Association, 1982)
A binding of GKS, the draft ISO standard for 2D graphics software, to the programming language C is presented, together with the principles underlying its design. The binding is compared with the binding to FORTRAN. An ...
A CSG LIST PRIORITY HIDDEN SURFACE ALGORITHM
(The Eurographics Association, 1985)
Several algorithms exist for visualizing geometric models defined by constructive solid geometry (CSG). Each of these algorithms is based on standard hidden surface methods, such as ray tracing, scan-line and z-buffer ...
The Use of Finite Element Theory for Simulating Object and Human Body Deformations and Contacts
(Eurographics Association, 1989)
This paper presents a method for combining image synthesis and modeling based on a finite element method (FEM) to get realistic intelligent images. FEM is used for modeling both elastically and plastically deformations of ...
