Synthesizing Feather Textures in Galliformes
(Blackwell Science Ltd and the Eurographics Association, 1995)The texture of feather is one of the most fascinating, complicated, and beautiful texture patterns in nature. In this paper, we propose a new and effective texture generation approach that uses the traits of iteration ... -
Discrete Ray-Tracing of Huge Voxel Spaces
(Blackwell Science Ltd and the Eurographics Association, 1995)The quality of images produced by Discrete Ray-Tracing voxel spaces is highly dependent on 3d grid resolution. The huge amount of memory needed to store such grids often discards discrete Ray-Tracing as a practical ... -
Generating a Texture Map from Object-Surface Texture Data
(Blackwell Science Ltd and the Eurographics Association, 1995)A number of 3D digitizing methods, including stereopsis, are capable of measuring not only an object s shape but also its surface texture. Measured shape data can be expressed as a polyhedron whose faces are triangular, ... -
Two-step Prediction and Image Deflection for Exact Head Tracking in Virtual Environments
(Blackwell Science Ltd and the Eurographics Association, 1995) -
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 ... -
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 ... -
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 ... -
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 ... -
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 ...
