An Incremental Alignment Algorithm for Parallel Volume Rendering
(Blackwell Science Ltd and the Eurographics Association, 1995)This paper introduces a data distribution scheme and an alignment algorithm for parallel volume rendering. The algorithm performs a single wrap-around shear transformation which requires only a regular inter-processor ... -
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 ... -
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 ... -
Morphological Operations for Color-Coded Images
(Blackwell Science Ltd and the Eurographics Association, 1995)The subject of this paper is the semantically based postprocessing of color-coded images such as classification results. We outline why the classical definition of mathematical morphology suffers if it is used for processing ... -
A Multimedia Constraint System1
(Blackwell Science Ltd and the Eurographics Association, 1995)The MADE constraint system provides excellent opportunities to introduce constraints in a multimedia application. Multimedia applications are not only a good place to experiment with constraint systems- constraints in a ... -
Multiresolution B-spline Radiosity
(Blackwell Science Ltd and the Eurographics Association, 1995)This paper introduces a kind of new wavelet radiosity method called multiresolution B-spline radiosity, which uses B-splines of different scales to represent radiosity distribution functions. A set of techniques and ... -
A new radiosity approach for regular objects: application to ruled surfaces
(Blackwell Science Ltd and the Eurographics Association, 1995)This paper introduces a new approach in the radiosity method. The main principle applied here, is the improvement of form factor computation by the knowledge of the model properties. More precisely, if surfaces describing ... -
Object Calibration for Augmented Reality
(Blackwell Science Ltd and the Eurographics Association, 1995)Augmented reality involves the use of models and their associated renderings to supplement information in a real scene. In order for this information to be relevant or meaningful, the models must be positioned and displayed ... -
A Quick Rendering Method Using Basis Functions for Interactive Lighting Design
(Blackwell Science Ltd and the Eurographics Association, 1995)When designing interior lighting effects, it is desirable to compare a variety of lighting designs involving different lighting devices and directions of light. It is, however, time-consuming to generate images with many ... -
A rational model of the surface swept by a curve*
(Blackwell Science Ltd and the Eurographics Association, 1995)This paper shows how to construct a rational Bezier model of a swept surface that interpolates N frames (i.e., N position/orientation pairs) of a fixed rational space curve c(s) and maintains the shape of the curve at all ... -
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 ... -
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 ... -
Reasoning About Gestural Interaction
(Blackwell Science Ltd and the Eurographics Association, 1995)Many of the reported developments in the design of virtual spaces or visualisation systems are based on improvements in technology, either physical devices or algorithms for achieving realistic renderings within real-time ... -
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 ... -
Shading with Curve Light Sources1
(Blackwell Science Ltd and the Eurographics Association, 1995)A new shading model for curve light sources is presented. It accounts for both diffuse reflection and specular reflection of the illuminated surface. By regarding a linear light source as a directional quadrilateral light ... -
Sketching 3D Animations
(Blackwell Science Ltd and the Eurographics Association, 1995)We are interested in providing animators with a general-purpose tool allowing them to create animations using straight-ahead actions as well as pose-to-pose techniques. Our approach seeks to bring the expressiveness of ... -
Spherical Triangular B-splines with Application to Data Fitting
(Blackwell Science Ltd and the Eurographics Association, 1995)Triangular B-splines surfaces are a tool for representing arbitrary piecewise polynomial surfaces over planar triangulations, while automatically maintaining continuity properties across patch boundaries. Recently, Alfeld ... -
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 ... -
