    • Automatic Generation of Multiresolution Boundary Representations 

      Andujar, C.; Ayala, D.; Brunet, P.; Arinyo, R. Joan; Sole, J. (Blackwell Science Ltd and the Eurographics Association, 1996)
      The paper focuses on automatic simplification algorithms for the generation of a multiresolution family of solid models from an initial boundary representation of a polyhedral solid. An algorithm for general polyhedra based ...

    • Mesh Simplification 

      Algorri, Maria-Elena; Schmitt, Francis (Blackwell Science Ltd and the Eurographics Association, 1996)
      Mesh simplification is an important stage after surface reconstruction since the models produced can contain a large number of polygons making them difficult to manipulate. In this paper we present a mesh simplification ...

    • Full-range approximation of triangulated polyhedra. 

      Ronfard, Remi; Rossignac, Jarek (Blackwell Science Ltd and the Eurographics Association, 1996)
      We propose a new algorithm for automatically computing approximations of a given polyhedral object at different levels of details. The application for this algorithm is the display of very complex scenes. where many objects ...

    • Real-time Volumetric Deformable Models for Surgery Simulation using Finite Elements and Condensation 

      Bro-Nielsen, Morten; Cotin, Stephane (Blackwell Science Ltd and the Eurographics Association, 1996)
      This paper discusses the application of 3D solid volumetric Finite Element models to surgery simulation. In particular it introduces three new ideas for solving the problem of achieving real-time performance for these ...

    • 3D Interactive Topological Modeling using Visible Human Dataset

      Availability of Visible Human Dataset (VHD)has provided numerous possibilities for its exploitation in both medical applications and 3D animation. In this paper, we present our interactive tools which enable extraction of ...

    • Symbiosis of Virtual Reality and Scientific Visualization System 

      Haase, Helmut (Blackwell Science Ltd and the Eurographics Association, 1996)
      This paper describes a concept for the symbiosis of a virtual reality system and a system for scientific visualization, as well as an implementation (called ISVAS-VR) to evaluate the concept. The idea is to preserve the ...

    • Incremental Volume Rendering Using Hierarchical Compression 

      Haley, Michael B.; Blake, Edwin H. (Blackwell Science Ltd and the Eurographics Association, 1996)
      We present a new algorithm here for efficient incremental rendering of volumetric datasets. The primary goal of this algorithm is to give average workstations the ability to efficiently render volume data received over ...

    • A Platform for User-Tailored Interaction Development in 2D, 3D, and VR 

      Encarnacao, L. Miguel; Fechter, Jurgen; Grunert, Thomas; Strasser, Wolfgang (Blackwell Science Ltd and the Eurographics Association, 1996)
      The discussion on the advantages and disadvantages of 2D, 3D, and VR interfaces and their applicability to different types of systems, users, and information led to a series of stand-alone implementations that lack the ...

    • Demand-Driven Geometry Transmission for Distributed Virtual Environments 

      Schmalstieg, Dieter; Gervautz, Michael (Blackwell Science Ltd and the Eurographics Association, 1996)
      We present a strategy for rendering in distributed virtual environments. A geometry database is maintained by a server, while users invoke individual clients to interact with the environment. Instead of downloading a ...

    • 3D Reconstruction of Complex Polyhedral Shapes from Contours using a Simplified Generalized Voronoi Diagram 

      Oliva, J-M.; Perrin, M.; Coquillart, S. (Blackwell Science Ltd and the Eurographics Association, 1996)
      We are interested in modelling the suface of very irregular objects known through a few planar polygonal cross-sections. This problem is considered difficult when severe topology and morphology variations appear between ...

    • Incremental constraint modelling in a feature modelling system 

      Laakko, Timo; Mantyla, Martti (Blackwell Science Ltd and the Eurographics Association, 1996)
      The techniques of constraint propagation have recently been successfully applied to feature-based design. Because of their speed, constraint propagation methods allow incremental design and rapid local modifcations of the ...

    • Integrating Computer Animation and Multimedia 

      Preston, Martin; Hewitt, Terry (Blackwell Science Ltd and the Eurographics Association, 1996)

    • BOXTREE: A Hierarchical Representation for Surfaces in 3D 

      Barequet, Gill; Chazelle, Bernard; Guibas, Leonidas J.; Mitchell, Joseph S.B.; Tal, Ayellet (Blackwell Science Ltd and the Eurographics Association, 1996)
      We introduce the boxtree, a versatile data structure for representing triangulated or meshed surfaces in 3D. A boxtree is a hierarchical structure of nested boxes that supports efficient ray tracing and collision detection. ...

    • Interpolatory Subdivision on Open Quadrilateral Nets with Arbitrary Topology 

      Kobbelt, Leif (Blackwell Science Ltd and the Eurographics Association, 1996)
      A simple interpolatory subdivision scheme for quadrilateral nets with arbitrary topology is presented which generates C1 surfaces in the limit. The scheme satisfies important requirements for practical applications in ...

    • An Energy-Based Approach for Contact Force Computation 

      Faure, Francois (Blackwell Science Ltd and the Eurographics Association, 1996)
      A new approach for computing resting contact forces between solids is presented, which handles both static and sliding friction, while avoiding the problems arising from previous approaches. Each iteration provides values ...

    • Reusable Radiosity Objects 

      Ouhyoung, Ming; Chuang, Yung-Yu; Liang, Rung-Huei (Blackwell Science Ltd and the Eurographics Association, 1996)
      Because of the view independence and photo realistic image generation in a diffuse environment, radiosity is suitable for an interactive walk through system. The drawback of radiosity is that it is time-consuming in form ...
