  • Virtual Actors’ Behaviour for 3D Interactive Storytelling 

    Cavazza, Marc; Charles, Fred; Mead, Steven J.; Strachan, Alexander I. (Eurographics Association, 2001)
    In this paper, we describe a method for implementing intelligent behaviour for artificial actors in the context of interactive storytelling. We have developed a fully implemented prototype based on the Unreal™ game engine ...

    Figueroa, Pablo; Green, Mark; Hoover, H. James (Eurographics Association, 2001)
    We present 3dml, a markup language for 3D interaction techniques and virtual environment applications that involve non-traditional devices. 3dml has two main purposes: readability and rapid development. Designers can read ...
  • Mayhem in Online Game and Virtual Environment Development 

    Oliveira, Manuel Fradinho Duarte; Crowcroft, Jon; Slater, Mel (Eurographics Association, 2001)
    We present Mayhem, which is a prototype of a Massive Online Role Playing Game (MORPG), where novel research in the field of Virtual Environments (VEs) is combined with the requirements of online games. This results in a ...
  • Complexity Reduction of Catmull-Clark/Loop Subdivision Surfaces 

    Steenberg, Eskil (Eurographics Association, 2001)
    By applying a filter this algorithm can reduce the number of polygons generated by subdividing a mesh dynamically. This algorithm is designed especially for real-time engines where the geometrical complexity is critical. ...
  • Animating cuts with on-the-fly re-meshing 

    Ganovelli, Fabio; O’Sullivan, C. (Eurographics Association, 2001)
    The problem of defining a model for deformable objects which allows the user to perform cuts is still open. Generally speaking, the reason is that such a task affects the connectivity and the topology of the mesh, while ...
  • Individualising Human Animation Models 

    Ju, Xiangyang; Siebert, J. Paul (Eurographics Association, 2001)
    Realistic human body animation requires accurate body geometry, realistic textures and believable behaviours. Existing human animation models provide excellent tools to control articulated motion and body surface deformations ...
  • Artist Driven Expressive Graphics 

    Mason, Kaye; Carpendale, Sheelagh (Eurographics Association, 2001)
    Current methods in non-photorealistic graphics can place a heavy emphasis on the algorithm, as opposed to the artist. In this paper, we analyse these trends, and present a conceptual framework for putting control back in ...
  • Real-Time Procedural Animation of Trees 

    Barron, Jeremy T.; Sorge, Brian P.; Davis, Timothy A. (Eurographics Association, 2001)
    Creating models of living flora, such as trees and grass, has been a challenge in computer graphics for many years. Animating these objects to move realistically in reaction to natural phenomena, such as wind and rain, ...
  • Redirected Walking 

    Razzaque, Sharif; Kohn, Zachariah; Whitton, Mary C. (Eurographics Association, 2001)
    Redirected Walking, a new interactive locomotion technique for virtual environments (VEs), captures the benefits of real walking while extending the possible size of the VE. Real walking, although natural and producing a ...
  • Improvement of the printing model in multi-colored and multi-woodblock virtual printing 

    Mizuno, Shinji; Ushida, Akihide; Okada, Minoru; Toriwaki, Jun-ichiro; Yamamoto, Shinji (Eurographics Association, 2001)
    In this paper, we propose a physically based model for the printing process in the virtual woodblock printing for improvement of printing quality. Virtual printing is a simulation of real printing using “woodblocks”, “a ...
  • Metaprogramming for the Generation of Nonparametric Curves 

    Boyer, Vincent (Eurographics Association, 2001)
    One of the most important functions of paintboxes is drawing curves. These primitives have been programmed and the user can never add a new program which computes the discrete points of a given function. Using metaprogramming ...
  • A Visualization System for the Clinical Evaluation of Cerebral Aneurysms from MRA Data 

    Perrin, James S.; Lacey, A.; Laitt, R.; Jackson, A.; John, Nigel W. (Eurographics Association, 2001)
    This paper details a work-in-progress application under development as part of a clinical visualization project. The software has been designed to meet the specific needs of interventional neuro-radiologists evaluating the ...
  • Data driven motion transitions for interactive games 

    Mizuguchi, Mark; Buchanan, John; Calvert, Tom (Eurographics Association, 2001)
    In 3D video games that employ human characters, a series of animations is required to display a character’s motion. The current approach is to use stored animation sequences, either motion captured or hand animated, and ...
  • Proxy Simulations for Efficient Dynamics 

    Chenney, Stephen; Arikan, Okan; Forsyth, D. A. (Eurographics Association, 2001)
    Proxy simulations reduce the cost of simulation in large virtual worlds, such as those used in training simulations or computer games. A proxy takes the place of an accurate simulation for objects that are out of view, ...
  • Free-Form Deformation of Solid Models in CSR 

    Hui, K. C.; Lai, C.F. (Eurographics Association, 2001)
    Existing free-form deformation (FFD) techniques deform an object by deforming the space enclosing the object. Points on the object are thus deformed relative to the undeformed space (or world space). The deformed object ...
  • Improved Rendering with Dégradé 

    Boyer, Vincent; Sobczyk, Dominique; Bourdin, Jean-Jacques (Eurographics Association, 2001)
    In most paintboxes drawing (and filling) the picture and render the picture are two different steps and tools. Dégradé presents an efficient filling rendering tool: an efficient collection of effect filling. In Dégradé the ...
  • An On-line Occlusio-Culling Algorithm for FastWalkthrough in Urban Areas 

    Wang, Yusu; Agarwal, Pankaj K.; Har-Peled, Sariel (Eurographics Association, 2001)
    We describe a fast algorithm to speed up rendering of scenes for walkthroughs in urban environments. Our occlusion culling algorithm takes advantage of temporal coherence in image space. As such, occlusion calculation is ...
  • Simplification of implicit skeletal models 

    Lucas, Laurent; Prevost, Stephanie (Eurographics Association, 2001)
    In this paper, we describe a hierarchical representation of unions of balls (UoB) applied to volume graphics. We present an algorithm that generates stable implicit volumes at different levels of resolution in the form of ...
  • Automatic Animated Face Modeling Using Multiview Video 

    Wu, Fu-Che; Murphy, Chien-Chang Ho; Ouhyoung, Ming (Eurographics Association, 2001)
    An image-based 3-D modeling system is presented in this paper. Our modeling system consists of three main stages: camera calibration, depth estimation and 3-D geometry reconstruction. All of these steps are executed ...
  • Fractal approximation of surfaces based on projected IFS attractors 

    Guerin, Eric; Tosan, Eric; Baskurt, Atilla (Eurographics Association, 2001)
    A method for approximating smooth or rough surfaces defined in R3 is introduced. A fractal model called projected IFS model allows the extension of the iteration space to a barycentric space Rn2 by enriching the classical ...
