Feature Sensitive Remeshing
(Blackwell Publishers Ltd and the Eurographics Association, 2001)Remeshing artifacts are a fundamental problem when converting a given geometry into a triangle mesh. We propose a new remeshing technique that is sensitive to features. First, the resolution of the mesh is iteratively ... -
Visualization of Isosurfaces with Parametric Cubes
(Blackwell Publishers Ltd and the Eurographics Association, 2001)To render images from volume datasets, an interpolation method also called reconstruction is needed. The level of details of the resultant image closely depends on the filter used for reconstruction. We propose here a new ... -
Detection of Salient Curvature Features on Polygonal Surfaces
(Blackwell Publishers Ltd and the Eurographics Association, 2001)We develop an approach for stable detection of perceptually salient curvature features on surfaces approximated by dense triangle meshes. The approach explores an "area degenerating" effect of the focal surface near its ... -
Generalized Stochastic Sampling Method for Visualization and Investigation of Implicit Surfaces
(Blackwell Publishers Ltd and the Eurographics Association, 2001)Recently we proposed the stochastic sampling method (SSM), which can numerically generate sample points on complicated implicit surfaces quickly and uniformly. In this paper we generalize the method in two aspects: (1) We ... -
Mesh Optimization for Polygonized Isosurfaces
(Blackwell Publishers Ltd and the Eurographics Association, 2001)In this paper, we propose a method for improvement of isosurface polygonizations. Given an initial polygonization of an isosurface, we introduce a mesh evolution process initialized by the polygonization. The evolving mesh ... -
Adaptive Nonlinear Finite Elements for Deformable Body Simulation Using Dynamic Progressive Meshes
(Blackwell Publishers Ltd and the Eurographics Association, 2001)Realistic behavior of deformable objects is essential for many applications such as simulation for surgical training. Existing techniques of deformable modeling for real time simulation have either used approximate methods ... -
Modeling Dynamic Hair as a Continuum
(Blackwell Publishers Ltd and the Eurographics Association, 2001)In this paper we address the difficult problem of hair dynamics, particularly hair-hair and hair-air interactions. To model these interactions, we propose to consider hair volume as a continuum. Subsequently, we treat the ... -
Modeling Stochastic Dynamical Systems for Interactive Simulation
(Blackwell Publishers Ltd and the Eurographics Association, 2001)We present techniques for constructing approximate stochastic models of complicated dynamical systems for applications in interactive computer graphics. The models are designed to produce realistic interaction at low cost.We ... -
A High Performance Solver for the Animation of Deformable Objects using Advanced Numerical Methods
(Blackwell Publishers Ltd and the Eurographics Association, 2001)Physically based modelling of deformable objects has become the most popular technique to model textiles, skin or human tissue. The crucial problem in the animation of deformable objects is the solution of the resulting ... -
Integrating Behavioural Animation Techniques
(Blackwell Publishers Ltd and the Eurographics Association, 2001)Our research focuses on animating autonomous virtual humans which are able to take decisions by themselves. We especially address in this paper the technical problem of integrating altogether the physical simulation of ... -
A low cost 3D scanner based on structured light
(Blackwell Publishers Ltd and the Eurographics Association, 2001)Automatic 3D acquisition devices (often called 3D scanners) allow to build highly accurate models of real 3D objects in a cost- and time-effective manner. We have experimented this technology in a particular application ... -
Global Illumination as a Combination of Continuous Random Walk and Finite-Element Based Iteration
(Blackwell Publishers Ltd and the Eurographics Association, 2001)The paper introduces a global illumination method that combines continuous and finite-element approaches, pre-serving the speed of finite-element based iteration and the accuracy of continuous random walks. The basic idea ... -
Incremental Updates for Rapid Glossy Global Illumination
(Blackwell Publishers Ltd and the Eurographics Association, 2001)We present an integrated global illumination algorithm including non-diffuse light transport which can handle complex scenes and enables rapid incremental updates. We build on a unified algorithm which uses hierarchical ... -
An Adaptive Method for Indirect Illumination Using Light Vectors
(Blackwell Publishers Ltd and the Eurographics Association, 2001)In computer graphics, several phenomema need to be taken into account when it comes to the field of photo-realism. One of the most relevant is obviously the notion of global, and more precisely indirect, illumination. In ... -
Fast Cloth Animation on Walking Avatars
(Blackwell Publishers Ltd and the Eurographics Association, 2001)This paper describes a fast technique for animating clothing on walking humans. It exploits a mass-spring cloth model but applies a new velocity directional modification approach to overcome its super-elasticity. The ... -
Interactive Computer Animation of Hand Gestures using Status Estimation with Multiple Regression Analysis
(Blackwell Publishers Ltd and the Eurographics Association, 2001)This paper presents a method of interactively generating natural hand gesture animation using reduced dimensionality from multiple captured data sequences of finger motions conducting specific tasks. This method is achieved ... -
Artist-Directed Inverse-Kinematics Using Radial Basis Function Interpolation
(Blackwell Publishers Ltd and the Eurographics Association, 2001)One of the most common tasks in computer animation is inverse-kinematics, or determining a joint configuration required to place a particular part of an articulated character at a particular location in global space. ... -
Rendering Pearlescent Appearance Based On Paint-Composition Modelling
(Blackwell Publishers Ltd and the Eurographics Association, 2001)We describe a new approach to modelling pearlescent paints based on decomposing paint layers into stacks of imaginary thin sublayers. The sublayers are chosen so thin that multiple scattering can be considered across ... -
Flexible Image-Based Photometric Reconstruction using Virtual Light Sources
(Blackwell Publishers Ltd and the Eurographics Association, 2001)Photometric reconstruction is the process of estimating the illumination and surface reflectance properties of an environment, given a geometric model of the scene and a set of photographs of its surfaces. For mixed-reality ... -
Automatic Lighting Design using a Perceptual Quality Metric
(Blackwell Publishers Ltd and the Eurographics Association, 2001)Lighting has a crucial impact on the appearance of 3D objects and on the ability of an image to communicate information about a 3D scene to a human observer. This paper presents a new automatic lighting design approach for ...
