ANIMA: An Interactive Tool for Scientific Data Animation
(Blackwell Science Ltd and the Eurographics Association, 1993)
This paper describes an animation interactive system that produces image sequences used to study the numerical results of scientific simulations. The fundamental goal of the system is to provide an easy method for observing ...
A Fractal Method for Digital Elevation Model Construction and its Application to a Mountain Region
(Blackwell Science Ltd and the Eurographics Association, 1993)
This paper presents and discusses the results of a methodology for the construction of Digital Elevation Models (DEM), based on mathematical principles of fractal geometry. Classical approaches to DEM are founded on numerical ...
Graphic Objects: A Mathematical Abstract Model for Computer Graphics
(Blackwell Science Ltd and the Eurographics Association, 1993)
This paper defines an abstract mathematical model for graphic systems which incorporates modelling operations. The model is based on the"graphic object" concept. A graphic object is an abstraction of a graphic entity. ...
The ARGOSI Classification Scheme for Graphics and Networking Applications
(Blackwell Science Ltd and the Eurographics Association, 1993)
ARGOSI is a project concerned with the relationship between standards for graphics and networking, as rejected in its full title: Applications Related Graphics and OSI Standards Integration. It is a collaborative project ...
The Method of Dynamic Palette Construction in Realistic Visualization Systems
(Blackwell Science Ltd and the Eurographics Association, 1993)
The paper describes the colour approximation problem and the method of dynamic palette construction is suggested for its solution. The method uses the graphic display palette based on the computed true colour of the ...
A Multiprocessor Implementation of Radiosity
(Blackwell Science Ltd and the Eurographics Association, 1993)
This paper describes a multi-processor implementation of form factor computation in the radiosity method. Form factors are computed using the ray casting method and the algorithm is enhanced with Binary Space Partition ...
The Generation of Circular Arcs on Hexagonal Grids
(Blackwell Science Ltd and the Eurographics Association, 1993)
The best disposition of a discrete set of points on the plane can be reached if the points are on a hexagonal grid. This paper describes two algorithms for circular arc mesh point selection on hexagonal grids. They find ...
The Generation of Straight Lines on Hexagonal Grids
(Blackwell Science Ltd and the Eurographics Association, 1993)
The best disposition of a discrete set of points on the plane can be reached if the points are on a hexagonal grid. This paper describes an algorithm for the generation of straight lines on hexagonal grids. It uses only ...
A Survey of 3D Solid Reconstruction from 2D Projection Line Drawings
(Blackwell Science Ltd and the Eurographics Association, 1993)
The reconstruction of a 3D object from its 2D projection(s) and its corresponding problem of 3D object recognition are two of the important research areas in the field of computer vision and artificial intelligence. ...
Pictorial Editing by Shape Matching Techniques
(Blackwell Science Ltd and the Eurographics Association, 1993)
A number ofpainting and retouching packages operate much like the artist s traditional canvas andpalette, with electronic toolsfunctioning like their studio counterparts. These programs, while offering an ample set of tools ...
