A Prototype of a Cooperative Visualization Workplace for the Aerodynamicist
(Blackwell Science Ltd and the Eurographics Association, 1993)
Several feasibility studies for cooperative visualization were performed based on an existing modular visualization system. Two different architectures for the implementation of a cooperative system were identified, ...
Automatic Reconstruction of Buildings from Stereoscopic Image Sequences
(Blackwell Science Ltd and the Eurographics Association, 1993)
A vision-based 3-D scene analysis system is described that is capable to model complex real-world scenes like streets and buildings automatically from stereoscopic image pairs. Input to the system is a sequence of stereoscopic ...
Modeling of Skylight and Rendering of Outdoor Scenes
(Blackwell Science Ltd and the Eurographics Association, 1993)
Photorealistic animated images are extremely effective for pre-evaluating visual impact of city renewal and construction of tall buildings. In order to generate a photorealistic image not only the direct sunlight but also ...
GKS-9x: Some Implementation Considerations
(Blackwell Science Ltd and the Eurographics Association, 1993)
The Graphical Kernel System (GKS) was published as an ISO standard for computer graphics programming in August 1985. GKS is now undergoing revision in ISO/IEC and at the time of writing the text of the Draft International ...
Abstract Interaction Objects
(Blackwell Science Ltd and the Eurographics Association, 1993)
The concept of an interactor has been introduced by Faconti and Paterno [6] as an abstraction of an entity in interactive graphics capable of both input and output. However the notion of interaction object need not be ...
Storage Support for Multidimensional Discrete Data in Multimedia Databases
(Blackwell Science Ltd and the Eurographics Association, 1993)
Multidimensional discrete data (MDD) is enormously important for multimedia applications since diverse types of such data are used simultaneously by any multimedia application. However, multidimensional discrete data is ...
Quality Control of an Interpolation Method for Discontinuous Parametric Surfaces
(Blackwell Science Ltd and the Eurographics Association, 1993)
In this paper we study a finite element interpolation method for fitting discontinuous parametric surfaces when the data points are the nodes of a curvilinear grid. Quality control of the interpolating surfaces is also ...
Nonsplitting Macro Patches for Implicit Cubic Spline Surfaces
(Blackwell Science Ltd and the Eurographics Association, 1993)
Macro patches are important for generating quadric or cubic implicit spline surfaces from the input of a polyhedron. All existing macro patches split the triangular facets of the polyhedron- this paper presents cubic ...
A New Radiosity Approach Using Area Sampling for Parametric Patches
(Blackwell Science Ltd and the Eurographics Association, 1993)
A high precision illumination model is indispensable for lighting simulation and realistic image synthesis. For the purpose of improving realism, research on global illumination has been done, and several papers on radiosity ...
Scale-Invariant Minimum-Cost Curves: Fair and Robust Design Implements
(Blackwell Science Ltd and the Eurographics Association, 1993)
Four functionals for the computation of minimum cost curves are compared. Minimization of these functionals result in the widely studied Minimum Energy Curve (MEC), the recently introduced Minimum Variation Curve (MVC), ...
