Syntax Channelling and Other Issues affecting Innovation in the Graphical User Interface
(Blackwell Science Ltd and the Eurographics Association, 1995)Does the modern commercial Graphical User Interface constrain the developer of graphics applications into certain interaction styles? This paper looks at the Microsoft Windows environment as an example, with particular ... -
Realizing 3D Visual Programming Environments within a Virtual Environment
(Blackwell Science Ltd and the Eurographics Association, 1995)In the visual programming community, many interesting graphical metaphors have been reported upon for representing computer programs graphically. Most of them have a 2D or 2.5D appearance on the screen in order to reflect ... -
A Real-time Continuous Alphabetic Sign Language to Speech Conversion VR System
(Blackwell Science Ltd and the Eurographics Association, 1995)Many ways of communications are used between human and computer, while using gesture is considered to be one of the most natural way in a virtual reality system. Because of its intuitiveness and its capability of helping ... -
The HUMANOID Environment for Interactive Animation of Multiple Deformable Human Characters
(Blackwell Science Ltd and the Eurographics Association, 1995)We describe the HUMANOID environment dedicated to human modeling and animation for general multimedia, VR, and CAD applications integrating virtual humans. We present the design of the system and the integration of the ... -
Visibility and Dead-Zones in Digital Terrain Maps
(Blackwell Science Ltd and the Eurographics Association, 1995)The problem of detecting the visible and hidden areas of a topographic surface from a given viewpoint is well known, and has applications in GIS and other fields. The computational geometry literature is rich with solutions ... -
A Graph-Based Approach to Surface Reconstruction
(Blackwell Science Ltd and the Eurographics Association, 1995)A new approach to the reconstruction of a surface from an unorganized set of points in space is presented. The point set may for example be obtained with a laser scanner or a manual digitizing tool, and is the only source ... -
Modeling 3D Curves of Minimal Energy
(Blackwell Science Ltd and the Eurographics Association, 1995)Modeling a curve through minimizing its energy yields an overall smooth curve. A common way to model shape features is to perform the minimization subject to a number of interpolation constraints. This way of modeling is ... -
VR-VIBE: A Virtual Environment for Co-operative Information Retrieval
(Blackwell Science Ltd and the Eurographics Association, 1995)We present a virtual reality application called VR-VIBE which is intended to support the co-operative browsing and filtering of large document stores. VR-VIBE extends a visualisation approach proposed in a previous two ... -
The MADE Help System
(Blackwell Science Ltd and the Eurographics Association, 1995)MADE is the acronym for the ESPRIT project 6307, whose aim is to develop an object oriented multimedia application development environment. As part of this project the MADE help system is designed to be a distributed ... -
Distributed Augmented Reality for Collaborative Design Applications
(Blackwell Science Ltd and the Eurographics Association, 1995)This paper presents a system for constructing collaborative design applications based on distributed augmented reality. Augmented reality interfaces are a natural method for presenting computer-based design by merging ... -
Rendering of Surface and Volume Details in Volume Data*
(Blackwell Science Ltd and the Eurographics Association, 1995)Aiming at the detail rendering in volume data, a new volume illumination model, called Composed Scattering Model (CSM), is presented. In order to enhance different details in volume data, scattering intensity is decomposed ... -
Using Procedural RenderMan Shaders for Global Illurnination
(Blackwell Science Ltd and the Eurographics Association, 1995)Global illumination techniques like radiosity or Monte-Carlo ray-tracing are becoming standard features of rendering systems. However, there is currently no accepted interface format which supports an appropriate ... -
Three Architectures for Volume Rendering
(Blackwell Science Ltd and the Eurographics Association, 1995)Volume rendering is a key technique in scientific visualization that lends itself to significant exploitable parallelism. The high computational demands of real-time volume rendering and continued technological advances ... -
Algorithms for Extracting Correct Critical Points and Constructing Topological Graphs from Discrete Geographical Elevation Data
