Computer Graphic Presentation of Road Data
(The Eurographics Association, 1983)
This paper presents a system for plotting traffic accidents and other data related to roads, on computer drawn maps. A method for simultaneous presentation of many different aspects of the road is also described.
Monte-Carlo Integration Applied to an Illumination Model
(Eurographics Association, 1988)
The use of Monte-Carlo integration together with stochastic sampling is very useful for dealing with the scattering phenomena that occur in the propagation and reflection of light. In this paper, these techniques have been ...
A CAD - SYSTEM FOR INTERACTIVE GRAPHICAL HANDLING OF HIERARCHICAL BLOCK DIAGRAM INFORMATION
(The Eurographics Association, 1980)
The CAD - system named GRIMBI is designed to support the functional modelling of large engineering systems. GRIMBI includes a data definition facility, to define model classes functionally and graphically. The data ...
GEO++ - A System for Both Modelling and Display
(Eurographics Association, 1989)
We present a new concept for a graphics system which we call GEO++ . Apart from the manipulation of groups (structures in PHIGS-terminology), GEO++ permits a direct access to the tree structure required for display. With ...
A Three-Dimensional Shaded Display Method for Voxel-Based Representation
(The Eurographics Association, 1985)
In this paper, methods for displaying solid objects represented by a three-dimensional array of voxels are described. The Linear Interpolating Projection Method is proposed as a method by which such objects can be projected ...
A Metric for Computing Adaptive Detail in Animated Scenes Using Object-Oriented Programming
(Eurographics Association, 1987)
A spatial metric for adapting the level of detail in a modelled object to achieve a convincing degree of realism on a display is formulated and illustrated with a simple implementation. This spatial metric is designed to ...
Accelerated Radiosity Method for Complex Environments
(Eurographics Association, 1989)
As form-factor calculation costs about 90% of the computing time when applying radiosity approach for realistic image synthesis, it is of great significance to reduce the required computation, An accelerated radiosity ...
Generative Scene Modelling
(Eurographics Association, 1987)
We describe a new theory of scene modelling that includes generative processes as integral components of scene descriptions. A single, uniform treatment of generative processes replaces the variety of ad hoc mechanisms ...
GRAPHICAL DATA BASES BUILT ON PEANO SPACE-FILLING CURVES
(The Eurographics Association, 1985)
This paper is devoted to the applications of Peano spacefilling curves for modelling graphics information. These curves, based on bit interlacing, allow the modelling, easily, of images with quadtrees, solids with octrees ...
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 ...
