Delauney Triangulations and the Radiosity Approach
(Eurographics Association, 1989)
The radiosity approach requires the subdivision of complex surfaces into simple components called patches. Since we assume to have constant intensity over a patch, the generation of regular patches is a desirable property ...
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 ...
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 ...
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 ...
Components, Frameworks and GKS Input
(Eurographics Association, 1989)
This paper was inspired by the Components/ Frameworks approach to a Reference Model for computer graphics, currently under discussion in the ISO computer graphics subject committee. The paper shows how a formal description ...
A Reference Model for the Visualisation of Multi-Dimensional Data
(Eurographics Association, 1989)
This paper presents a reference model for the development of systems for the visualization of multidimensional data. The purpose of the reference model is to build a conceptual basis for thinking about multi-dimensional ...
Subdivisions of Surfaces and Generalized Maps
(Eurographics Association, 1989)
The modeling of subdivisions of surfaces is of greatest interest in Geometric Modeling (in particular for Boundary Representation) , and many works deal with the definition of models, which enable the representation of ...
Visualisation of Digital Terrain Data
(Eurographics Association, 1989)
Visualisation technology has found practical application in the field of terrain data processing. A raster data base (RDB-) concept will be introduced, i.e. a multi-dimensional concept of terrain data using elevation data, ...
