Synthetic Vision and Audition for Digital Actors
(Blackwell Science Ltd and the Eurographics Association, 1995)We present an overview of some principles of synthetic vision and audition for digital autonomous actors in virtual worlds. After a short review of the state-of-the-art we focus on some aspects of synthetic vision 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 ... -
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 Direct Manipulation Interface for 3D Computer Animation
(Blackwell Science Ltd and the Eurographics Association, 1995)We present a new set of interface techniques for visualizing and editing animation directly in a single three-dimensional scene. Motion is edited using direct-manipulation tools which satisfy high-level goals such as"reach ... -
An Adaptive Spatial Subdivision of the Object Space for Fast Collision Detection of Animated Rigid Bodies
(Blackwell Science Ltd and the Eurographics Association, 1995)Collision detection tests between objects dominate run time simulation of rigid body animation. Traditionally, hierarchical bounding box tests are used to minimize collision detection time. But the bounding boxes do not ... -
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 ... -
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 ... -
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 ... -
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 ... -
Fast Shadowing Algorithm for Linear Light Sources
(Blackwell Science Ltd and the Eurographics Association, 1995)This paper presents a fast shadowing algorithm for linear light sources that uses a ray-oriented buffer. Space segmentation by the buffer guarantees that if a point is included in a subspace, all light rays toward the point ... -
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 ... -
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 ... -
Algorithms for Extracting Correct Critical Points and Constructing Topological Graphs from Discrete Geographical Elevation Data
(Blackwell Science Ltd and the Eurographics Association, 1995)Researchers in the fields of computer graphics and geographical information systems (GISs) have extensively studied the methods of extracting terrain features such as peaks, pits, passes, ridges, and ravines from discrete ... -
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 ... -
Thoughtful Drawings: A Computational Model of the Cognitive Nature of Children s Drawing
(Blackwell Science Ltd and the Eurographics Association, 1995)An interpretation of children s drawing is presented that is based on active perception of the world and the construction of an equivalent self contained two-dimensional world. This model is implemented in a computer program ... -
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 ... -
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 ... -
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 ... -
