• Binding Virtual Environments to Toolkit Capabilities 

  Smith, Shamus P.; Duke, David J. (Blackwell Publishers Ltd and the Eurographics Association, 2000)

  There are many toolkits and development environments that aid the process of constructing virtual environment applications. Many of these development environments encourage customising a virtual environment's design while ...

• Modelling virtual cities dedicated to behavioural animation 

  Thomas, Gwenola; Donikian, Stephane (Blackwell Publishers Ltd and the Eurographics Association, 2000)

  In order to populate virtual cities, it is necessary to specify the behaviour of dynamic entities such as pedestrians or car drivers. Since a complete mental model based on vision and image processing cannot be constructed ...

• LCTS: Ray Shooting using Longest Common Traversal Sequences 

  Havran, V.; Bittner, J. (Blackwell Publishers Ltd and the Eurographics Association, 2000)

  We describe two new techniques of ray shooting acceleration that exploit the traversal coherence of a spatial hierarchy. The first technique determines a sequence of adjacent leaf-cells of the hierarchy that is pierced by ...

• Automatic Generation of Virtual Woodblocks and Multicolor Woodblock Printing 

  Mizuno, S.; Kasaura, T.; Okouchi, T.; Yamamoto, S.; Okada, M.; Toriwaki, J. (Blackwell Publishers Ltd and the Eurographics Association, 2000)

  In this paper, we study a method to synthesize a multicolor virtual woodblock print by using several virtual woodblocks. It consists of two sections: carving and printing, to synthesize a virtual print. In the carving ...

• Integrating Occlusion Culling and Levels of Detail through Hardly-Visible Sets 

  Andujar, Carlos; Saona-Vazquez, Carlos; Navazo, Isabel; Brunet, Pere (Blackwell Publishers Ltd and the Eurographics Association, 2000)

  Occlusion culling and level-of-detail rendering have become two powerful tools for accelerating the handling of very large models in real-time visualization applications. We present a framework that combines both techniques ...

• Directional Discretized Occluders for Accelerated Occlusion Culling 

  Bernardini, Fausto; Klosowski, James T.; El-Sana, Jihad (Blackwell Publishers Ltd and the Eurographics Association, 2000)

  We present a technique for accelerating the rendering of high depth-complexity scenes. In a preprocessing stage, we approximate the input model with a hierarchical data structure and compute simple view-dependent polygonal ...

• Efficient Algorithms for Computing Conservative Portal Visibility Information 

  Jimenez, W. F. H.; Esperanca, C.; Oliveira, A. A. F. (Blackwell Publishers Ltd and the Eurographics Association, 2000)

  The number of polygons in realistic architectural models is many more than can be rendered at interactive frame rates. Typically, however, due to occlusion by opaque surfaces (e.g., walls), only small fractions of such ...

• Colour Section 

  Unknown author (Blackwell Publishers Ltd and the Eurographics Association, 2000)

• Automatic Surface Reconstruction from Point Sets in Space 

  Attene, Marco; Spagnuolo, Michela (Blackwell Publishers Ltd and the Eurographics Association, 2000)

  In this paper an algorithm is proposed that takes as input a generic set of unorganized points, sampled on a real object, and returns a closed interpolating surface. Specifically, this method generates a closed 2-manifold ...

• Surface Reconstruction based on Lower Dimensional Localized Delaunay Triangulation 

  Gopi, M.; Krishnan, S.; Silva, C.T. (Blackwell Publishers Ltd and the Eurographics Association, 2000)

  We present a fast, memory efficient algorithm that generates a manifold triangular mesh S passing through a set of unorganized points P R 3. Nothing is assumed about the geometry, topology or presence of boundaries in the ...

• Floating Points: A Method for Computing Stipple Drawings 

  Deussen, Oliver; Hiller, Stefan; Van Overveld, Cornelius; Strothotte, Thomas (Blackwell Publishers Ltd and the Eurographics Association, 2000)

  We present a method for computer generated pen-and-ink illustrations by the simulation of stippling. In a stipple drawing, dots are used to represent tone and also material of surfaces. We create such drawings by generating ...

• An Interactive Approach to Point Cloud Triangulation 

  Kobbelt, Leif P.; Botsch, Mario (Blackwell Publishers Ltd and the Eurographics Association, 2000)

  We present an interactive system for the generation of high quality triangle meshes that allows us to handle hybrid geometry (point clouds, polygons,. . .) as input data. In order to be able to robustly process huge data ...

• Generating Consistent Motion Transition via Decoupled Framespace Interpolation 

  Ashraf, G.; Wong, K. C. (Blackwell Publishers Ltd and the Eurographics Association, 2000)

  The framespace interpolation algorithm abstracts motion sequences as 1D signals, and interpolates between them to create higher dimension signals, with weights drawn from a user specified curve in a bounded region. We ...

• Motion Balance Filtering 

  Tak, Seyoon; Song, Oh-young; Ko, Hyeong-Seok (Blackwell Publishers Ltd and the Eurographics Association, 2000)

  This paper presents a new technique called motion balance filtering, which corrects an unbalanced motion to a balanced one while preserving the original motion characteristics as much as possible. Differently from previous ...

• Real Time Local Approximation of Deformations using Rotations 

  Maillot, Jerome (Blackwell Publishers Ltd and the Eurographics Association, 2000)

  Additional realism can be achieved in computer generated images using smooth and increasingly complex deformations. Though significant effort has been spent on improving these deformations, no general method has been ...

• A Vector-based Representation for Image Warping 

  Froumentin, Max; Labrosse, Frederic; Willis, Philip (Blackwell Publishers Ltd and the Eurographics Association, 2000)

  A method for image analysis, representation and re-synthesis is introduced. Unlike other schemes it is not pixel based but rather represents a picture as vector data, from which an altered version of the original image can ...

• Representing Animations by Principal Components 

  Alexa, Marc; Muller, Wolfgang (Blackwell Publishers Ltd and the Eurographics Association, 2000)

  In this paper, we present a representation for three-dimensional geometric animation sequences. Different from standard key-frame techniques, this approach is based on the determination of principal animation components ...

• A Video-Based 3D-Reconstruction of Soccer Games 

  Bebie, T.; Bieri, H. (Blackwell Publishers Ltd and the Eurographics Association, 2000)

  In this paper we present SoccerMan, a reconstruction system designed to generate animated, virtual 3D views from two synchronous video sequences of a short part of a given soccer game. After the reconstruction process, ...

• Video-based Approach to Human Animation 

  Lao, Zhiqiang; Li, Ling (Blackwell Publishers Ltd and the Eurographics Association, 2000)

  A method based on computer vision technologies is presented to determine the 3-D spatial locations of joints or feature points of a human body from human motion video. The proposed method first applies the geometric ...

• Unsteady Flow Visualization by Animating Evenly-Spaced Streamlines 

  Jobard, Bruno; Lefer, Wilfrid (Blackwell Publishers Ltd and the Eurographics Association, 2000)

  In recent years the work on vector field visualization has been concentrated on LIC-based methods. In this paper we propose an alternative solution for the visualization of unsteady flow fields. Our approach is based on ...
